For anyone who's looking at buying a power meter for the first time: (1) do it; if you're at all serious about biking, it's the most important upgrade you can get for your bike and (2) be aware that Shimano's meters (feature in this video) leave a lot to be desired. There are several better and cheaper meters out there. DC Rainmaker has some very good reviews that you probably should go through first before making a purchase.
Best piece of advice I’ve gotten is don’t look at the power when you’re out with friends. Keep the numbers for your solo and structured training sessions. Best of both: fun and improving
riding with friends is when you hit your PRs, as you desperately hold onto the wheels, while they surge up kickers at 40k an hour at least in my experience lol
Video idea suggestion: A comparison of the speeds of different kinds of bike when you put in the same power. E.g. how fast is a race bike at 250W vs how fast is a mountainbike with the same power, how much faster is a lighter bike, how much influence does tire pressure have, and so on.
It'd be nice if it included other types of bikes too that aren't performance oriented but instead are more commonly used by commuters and casual riders, like folding bikes, cruisers, dutch bikes, etc.
I ride with a power meter, Stages left crank arm. They're a useful tool for pacing and climbing. Do an FTP to find your zones and then on your head unit work to power zones 1-6. You then have "gears of effort" to ride in. Just like HR zones but more accurate. I climb in 3-4 and 2-3 in endrance. It's like cheating
@@Markhypnosis1 it's as opposed to someone who isn't using one at all or not using zones but fluctuating watts. Zones take away the guessing of effort needed. So on climb you can sit in zone 2 or 3 gear of effort and know the time and pace you will need to cover the climb without say burning out at the bottom. You can pre plan knowing which zone to apply on a particular route or race too.
@@parenthlete HR is great for steady efforts, but the lag makes it useless for short intense intervals. Using both is the key, because you can hit the same numbers at a lower HR and know your body is adapting (or, if a higher HR, maybe you need more recovery)

I have a left crank power meter, but dont really use it for training by power. I use it more for pacing, so i dont overdo in the beginning of a climb or for a strava sector PR. It works really well and by time you just know how hard you can go. All my PRs improved by a lot, on climbs and flats! Can very much recommend to get a power meter if you are into data and numbers.
i don't have a power meter and typically just go by vertical ascent speed for pacing climbs. is a power meter somehow better for that? (i get that it is better for pacing also for doing sprints on the flats)
@@sbjf it's absolutely better for that. Given how inaccurate some altimeters are, your VAM isn't going to give you a great idea of your exertion. Also, consider that a punchy climb is easily going to put you over 500W--are you going to trust an altimeter to tell you when you're about to blow up when that effort is likely only sustainable for around a minute? Another nice thing a power meter will do is let you accurately calculate your FTP, so you'll know that you can climb at at least that figure without exploding. Accurate FTP calculation can also give you a W' (W prime) calculation, which lets you know how much anaerobic "burst" power you have at a given time. It's like a battery gauge for your body! All of these cool metrics are only available with power meters, and the great news is that you can get one for under $400 these days.

I am trying to lose weight, to have a device that is able to track almost exactly how much calories you burned during a session is insanely valuable for people who care about weight loss, which I imagine is a MASSIVE amount of people. If someone can make a cheap cheap pedal power meter for the masses, and now with the ability to connect power meters to apple watches, that would be a very good selling product in my opinion. I don't think people in the cycling community see the value of this outside of their own training needs. Really really hope a product comes out soon like this.

As to Si's first point, I don't know about other brands of power meters, but you do not have to zero out Assioma power pedals. One of the benefits of those pedals, as well as their cost. Also, while no power meter is perfect, as long as whatever power meter you're using gives you consistent results, it doesn't matter. One last thing, Si references polarized training, which only has three zones, and the methodology is that you spend 80-90 percent of your time in zone 1 (base), and the rest in zone 3 (intervals), spending as little time as possible in zone 2. He says zone 2 base training during the video, which is probably because most people do a 5 or more zone training program, and zone 2 usually means base training effort.
Not sure which gospel you quote to say that polarized training has three zones. Afaik it's just a term. A synonym would be barbell training. The idea being you avoid the middle and you focus on the extremities of a barbell / poles of a sphere.

What speed can you hold up the hill? 8mph? 11mph? Whatever, doesn't matter. Let's use 8mph as what you were able to hold. Now every week go back and try and hold 'just a bit more speed'. Once you hold 8.5mph, move up to trying for 9mph. Then 9.5mph etc etc. Cheap, easy, free, effective. This also works on your flat speedwork. Mark off a quarter mile section of road, see how fast you can hold. Then come back and work on going just a bit faster every week. Done...

So that ur wahoo for instance will get cadence data from the power meter and also show that on the screen? Or u need a diffrent thing for that. (Sorry for possibly a dumb question, but is pretty new to road cycling myself and data. Been watching ur channel for years and also diffrent tours. But never thought/cared abour data) Also sorry if my English might be a bit of, its my second language 😅
Don’t have a power meter, yet with the type and amount of riding I do , I really don’t need one. But if I was truthful to myself, I would like one just to see what actual numbers I can put out. I am a bit of a stats geek/ nerd.
I was thinking about doing clubrides during racing season and threating them as C races (A being the most important, C being the least) and also sometimes during base/build season threating them as an unprecise but hard intervall training ride. Most of them happen of Saturdays and on Sunday I can go out for my long endurance ride.
Excellent job explaining using the power meter. I was hoping you would have a bit deeper, and explain the benefits of having two vs one power meter (other than the significant cost difference)? I have gone back and forth on Whether to install just one in the beginning and later install a second, or do I really need to have two? Any advise?
Just got a left sided Dura Ace 4iiii power meter and it’s not connecting well to Zwift or my watch. I have been using Garmin speed and cadence meter but I wanted accurate power reading. I downloaded the 4iiii app and calibrated the pm but it did only connected a bit to zwift but didn’t read. Do I need to remove the speedmeter or what could be the problem? All the reviews are saying that it easy too install and connect with zwift, not for me
Yes, the Bike+ power numbers are extremely accurate. DC Rainmaker's video showed they matched data from the power meter pedals he put on the bike almost perfectly. I've been doing Powerzone training inside on my Bike+ for over a year and it has improved my outdoor cycling immensely.
As a triathlete I really love the data. At some point you really get a feeling for the different pace zones which really helps not getting to fast. Also it's important if you do polarized training, as most people just naturally go too fast and too slow most of the time. Especially if you coming from a HIIT background, the numbers really help going slow.
One thing my coach emphasised is to not just track the numbers but also use them to try to feel what a particular effort feels like, so like what does zone 4 feel like and can you run/cycle in zone 4 by feel, for example. The more you can do that the better in tune with your body you can be as to how an effort should feel and whether you're out of your normal range and may need to alter your race Strat a little.
Correction, your power is not force multiplied by rpm, it is torque multiplied by cadence in radians-per-second. Which means your power = force X crank length X radians-per-second. There are 2*pi radians in one revolution and 60 seconds in a minute, so your power (watts) is force (newtons) multiplied by (crank length in metres*rpm*2*3.141)/60 or approximately: force multiplied by (crank length*rpm)/10. With a bit of mathematics and this correct formula, one can calculate how much force they put on the crank. It turns out you can't put much more force than your own body weight (newtons) due to the need for gravity to keep you planted. A little more force can be gained by bracing against the handlebars. To get more power past the maximum possible force you need to raise the other variable, the cadence.
Not all us are big-shot GCN presenters, and can't afford Dura-Ace. However, I did just buy the SRAM Rival crank based power meter. How are those "zero'd out?"
I am glad I'm retired and don't have to worry about riding by numbers. Maths was never my best subject anyway. I'm old school and just ride my bike on feeling ;)
Don't you have these "oh, this feels really hard today" moments? Then I see the watts and know if it IS really hard or if I'm just lazy today. If lazy: Get yourself together and do your watts! ^^
Can't ride to power when racing, learn how to listen to your body so I totally agree. started racing in 1976. still no power meter on my bike. Also can't use one on the track
I rode on feeling but when I got a power meter it showed I'd been using the wrong cadence. Even though the cadence felt the best, the power meter showed that I made the same power with less fatigue if I raised the cadence 15 rpm. It felt odd at first but the numbers do not lie, and now this is my preferred cadence.
how about riding because you enjoy it. Does every ride have to be a workout for the next tour de france? Enjoy your rides and stop tracking everything you do you will enjoy it more and you can check any stats later when the ride is over or dont. Just have fun with riding you will get more out of it.
Or we can all do ourselves and be happy 😃 I personally love data. I still enjoy my rides with my friends or solo, but I like seeing my data after my rides.
I cycle to visit places, shop, and just enjoy the views on a mamachari. That said, I've been interested in getting a power meter just because I'm curious about those various values I've heard about and think it'd be interesting to see more stats regarding my trips other than just distance and speed. It's a bit of a shame though, since my bike is probably cheaper than the cheapest power meters out there, so I'll probably just hold out for a while instead.
me too, I'm curious about all these kilowatt shanenigans, but the price is just WAY too much for a non-competitive cyclist like me. I'd rather buy a second-hand fine bike than a power meter
Just done my first ride with 4iiiiiiiiiiiiiii left crank power meter. The wildly fluctuating numbers frustrated me. Are all power meters like that? And what setting is best for an accurate reading - 10 sec avg, 30 sec?
Things I wish I’d known, don’t buy a garmin one……garbage. Struggles connecting, eventually a new door came out changed the battery door as per garmin, won’t connect at all now, also the pedal body wore out inside two years, which garmin wouldn’t warranty. Took me a lot of time and money to work that out, spread the word.
Fellas at Garmin have become way too comfortable in their office chairs as they think simply because they built up a famous brand they will be able to sell only crap in the future for fortunes lol.
Something interesting from the recent Giro was a poll amongst riders about their computer. Most said they only really check distance remaining and that the power meter can be quite disheartening for them ;)
It's really interesting, Tadej Pogacar famously climbed La Planche des Belle Filles without a computer during his Tour de France Winning Final TT in 2020
@@gcn Makes total sense in a TT though, but Pog is another animal entirely - oh that constant lone struggle to get the right balance between effort and pace. PS: The final showdown between Pogacar and Roglic was one of the best I've ever seen.
@@BikePappy tbh, I currently struggle to find out which cleats i have :D Just started 7 months ago, only used my roadbike with a smart trainer at home the first 5 month and I've never been on a group ride yet. I googled the Look/KEO cleats and found mine advertised as SPD. I google for SPD and they look like the MTB cleats (I use 3 point roadbike cleats/shoes). That got me confused :(
Thanks for viddeo, just what i needed! But do i ride with 3 seconds average power or do i just set the zones. And do you use average normalized power after you are done training to find the zone you have trained in?
You ride with 3 sec average, raw numbers fluctuate way too much. You do not find the zone you have trained in by taking the average or anything else from an entire ride, for seeing in which zone you are training the same 3 sec average is the best measure too. On Strava for example you can then see for an entire ride how much time you have spent in which zone.
@@MrLEGONATHAN Assuming you apply high torque as well as high rpm. Most people struggle to do this, the ability to do it is what separates the pros from everyone else.
@@Ed.R it’s like driving a car really: diesels produce more torque (force) than a petrol but at less RPMs for the same power. Petrols produce less torque but higher RPMS to produce the same power
I would love a power metre just to see if the feeling of getting fitter actually translates to real number improvements. Unfortunately they are too expensive for my budget.
Crank if you can get one that fits. More protected from the road, and mechanically it is a better place for a strain gauge to take an accurate reading - reviews tend to say that crank is more accurate than pedal.
@@BC-wj8fx i should wait until i get a new bike i guess and do a bike fit before buying a power meter? Because it might be possible i need another crank length?
@@mikewow yes or you can replace just the crank set. There was no exact match for my power meter crank so I used the one with the nearest Q-factor and used some washers to shim the pedal out.
As a regular 59 year old rider using a 2011 Specialized Allez, a Power Meter is a NICE TO HAVE and expensive add-on to your machine. Since I only ride just for the sheer joy of riding (100 kms in 4 hours), I can put the cost of that add-on to something else....just my 2 cents....
Is there any word from shimano regarding the extensive crank failures on modern cranks? #askGCNtech Also shimano has never been able to produce an accurate dual sided crank PM, is this generation any better? #askGCNtech
I just noticed that I always zeroed my PM in horizontal and not vertical haha When he zeroed it, I was like: Is he doing it wrong or me the whole time?
My spider power meter (Quarq DZero) specifically said to zero it in the vertical position (drive-side crank at 6 o’clock). But fortunately it also auto-calibrates so I don’t do that often!
I would really like it if people on "social" group rides would just put their head units in their jersey pockets and download stuff when they get home. Between power obsessions and strava segments, I don't know how many friendly group rides have been ruined by " I've got to watch my numbers" or " sorry, I have to try for a PB on this segment."
Do you ride with a power meter?
No but I have been saving to buy one

Don’t have a power meter, yet with the type and amount of riding I do , I really don’t need one. But if I was truthful to myself, I would like one just to see what actual numbers I can put out. I am a bit of a stats geek/ nerd.
I was thinking about doing clubrides during racing season and threating them as C races (A being the most important, C being the least) and also sometimes during base/build season threating them as an unprecise but hard intervall training ride. Most of them happen of Saturdays and on Sunday I can go out for my long endurance ride.
Warren buffet doesn't agree with YOU.
He says we must stay home and make some money just like him.
Excellent job explaining using the power meter. I was hoping you would have a bit deeper, and explain the benefits of having two vs one power meter (other than the significant cost difference)? I have gone back and forth on Whether to install just one in the beginning and later install a second, or do I really need to have two? Any advise?
Nice knock against the peloton bike!😂
Fantastic concise vid from Si !
But some one should have told him those horizontal patterns on his GCN socks don't do his ankles any favours , 😂😱😂
The Canyon bike that Simon rides look amazing!! Could someone please tell me the model of the bike? Thank you!
It literally looks like my dream byke.
Canyon Aeroad Cf SLX older model
@@xXxLegendZoneTVxXx thank you!!
Aeroad CFR not CFslx
Just got a left sided Dura Ace 4iiii power meter and it’s not connecting well to Zwift or my watch.
I have been using Garmin speed and cadence meter but I wanted accurate power reading. I downloaded the 4iiii app and calibrated the pm but it did only connected a bit to zwift but didn’t read.
Do I need to remove the speedmeter or what could be the problem?
All the reviews are saying that it easy too install and connect with zwift, not for me
Please see Dr Stephen Seiler for videos on the 80/20 approach to cycling, where most of your sessions will be in zone 2
Yup, his video was enlightening.
Love the little dig at Peloton Bikes.
Just FYI the peloton bike (at least the + version) does have the ability to calibrate it's power meter.
Yes, the Bike+ power numbers are extremely accurate. DC Rainmaker's video showed they matched data from the power meter pedals he put on the bike almost perfectly. I've been doing Powerzone training inside on my Bike+ for over a year and it has improved my outdoor cycling immensely.
@@davidfry3912 DCR just got lucky with his purchase. Read Peloton's documentation. It is +/- 10% accuracy for the Bike+.
As a triathlete I really love the data. At some point you really get a feeling for the different pace zones which really helps not getting to fast. Also it's important if you do polarized training, as most people just naturally go too fast and too slow most of the time. Especially if you coming from a HIIT background, the numbers really help going slow.
One thing my coach emphasised is to not just track the numbers but also use them to try to feel what a particular effort feels like, so like what does zone 4 feel like and can you run/cycle in zone 4 by feel, for example.
The more you can do that the better in tune with your body you can be as to how an effort should feel and whether you're out of your normal range and may need to alter your race Strat a little.
Correction, your power is not force multiplied by rpm, it is torque multiplied by cadence in radians-per-second. Which means your power = force X crank length X radians-per-second. There are 2*pi radians in one revolution and 60 seconds in a minute, so your power (watts) is force (newtons) multiplied by (crank length in metres*rpm*2*3.141)/60 or approximately: force multiplied by (crank length*rpm)/10. With a bit of mathematics and this correct formula, one can calculate how much force they put on the crank. It turns out you can't put much more force than your own body weight (newtons) due to the need for gravity to keep you planted. A little more force can be gained by bracing against the handlebars. To get more power past the maximum possible force you need to raise the other variable, the cadence.
Not all us are big-shot GCN presenters, and can't afford Dura-Ace. However, I did just buy the SRAM Rival crank based power meter. How are those "zero'd out?"
I have the same power meter. Use the AXS app or a headunit like in the video.
great videos, very informative and entertaining (new sub)
Yes, Rotor 2inpower on Supersix EVO.
I am glad I'm retired and don't have to worry about riding by numbers. Maths was never my best subject anyway. I'm old school and just ride my bike on feeling ;)
Don't you have these "oh, this feels really hard today" moments? Then I see the watts and know if it IS really hard or if I'm just lazy today. If lazy: Get yourself together and do your watts! ^^
Can't ride to power when racing, learn how to listen to your body so I totally agree. started racing in 1976. still no power meter on my bike. Also can't use one on the track
I rode on feeling but when I got a power meter it showed I'd been using the wrong cadence. Even though the cadence felt the best, the power meter showed that I made the same power with less fatigue if I raised the cadence 15 rpm. It felt odd at first but the numbers do not lie, and now this is my preferred cadence.
Very informative filum :) once I’d re watched the first bit twice but then I am dyslexic 🙂
The lap button works great for intervals and holding a specific power output.
But you'll get more praise from making wealth than from cycling.
Do you have to buy tires separately or they come in with a bike
What's the tyre pressure Simon. Seems a lot of rubber flat on the road
I thought I am the only one who noticed that.
This guy is smashing the pedals, and he is able to talk normally .
Do favero pedels need to be calibreted for every ride?
how about riding because you enjoy it. Does every ride have to be a workout for the next tour de france? Enjoy your rides and stop tracking everything you do you will enjoy it more and you can check any stats later when the ride is over or dont. Just have fun with riding you will get more out of it.
Or we can all do ourselves and be happy 😃
I personally love data. I still enjoy my rides with my friends or solo, but I like seeing my data after my rides.
@@Darsithis I love data too: HR, power, cadence, total gradient etc. I don’t race triathlons anymore but I do just love graphs and numbers 😅
It’s almost like you didn’t watch the end of the video. 😉
What kind of watts did you produce on your Penny Farthing?
Great information. 🤟😎
Force X distance X cadence = power. Si left out the crankarm length.
2:32 Okay that 'gym workout' made me laugh, I know people like that, but you forgot to *take selfies.* That would make the workout complete
This has got to be the first time Simon ever been in a weight Room!
I cycle to visit places, shop, and just enjoy the views on a mamachari. That said, I've been interested in getting a power meter just because I'm curious about those various values I've heard about and think it'd be interesting to see more stats regarding my trips other than just distance and speed. It's a bit of a shame though, since my bike is probably cheaper than the cheapest power meters out there, so I'll probably just hold out for a while instead.
me too, I'm curious about all these kilowatt shanenigans, but the price is just WAY too much for a non-competitive cyclist like me.
I'd rather buy a second-hand fine bike than a power meter
Yes, pricing is a shame. Hard to believe the little wire in there costs more than a Cent.
Just done my first ride with 4iiiiiiiiiiiiiii left crank power meter. The wildly fluctuating numbers frustrated me. Are all power meters like that? And what setting is best for an accurate reading - 10 sec avg, 30 sec?
If you have it set to show instantaneous power then numbers will jump about, try 3 second power or higher
Things I wish I’d known, don’t buy a garmin one……garbage. Struggles connecting, eventually a new door came out changed the battery door as per garmin, won’t connect at all now, also the pedal body wore out inside two years, which garmin wouldn’t warranty. Took me a lot of time and money to work that out, spread the word.
Fellas at Garmin have become way too comfortable in their office chairs as they think simply because they built up a famous brand they will be able to sell only crap in the future for fortunes lol.
Don’t buy a garmin anything experience has told me …
Personally, I would go with the 4IIII left side crank. It has no parts to wear out. It is super reliable, and you can quickly transfer it to any bike.
Does the same 20 minute ride at a constant power level, and the same cadence, but with different bikes, feel the same?
Effort-wise, it does. But handling makes the experience a little different.
Something interesting from the recent Giro was a poll amongst riders about their computer. Most said they only really check distance remaining and that the power meter can be quite disheartening for them ;)
It's not uncommon for pros to train to power to get fitter, but ride entirely on feel during the race.
@@gcn Absolutely hear you. That was specifically for the race. I'm sure they all use power meters for training ;)
It's really interesting, Tadej Pogacar famously climbed La Planche des Belle Filles without a computer during his Tour de France Winning Final TT in 2020
@@gcn Makes total sense in a TT though, but Pog is another animal entirely - oh that constant lone struggle to get the right balance between effort and pace. PS: The final showdown between Pogacar and Roglic was one of the best I've ever seen.
just wondering where did you put the wahoo speed meter?
(didn't see it on any of the wheels)
the wahoo head unit can still measure speed through GPS data albeit not as accurate when a speed sensor is available
@@kriscythe aah okay, thanks! I bought a bundle with everything in it so that's why I wondered
Great shoes!!!!
Unfortunately impossible to find in that color 😒
Currently I am actively looking for a powermeter pedal. So nice timing :) and good video!
Favero Assiomas unless you hate look keo style cleats.
@@talonlan funny enough that you should recommend those. They are my current favorite :)
Agreed. Assiomas are solid. They now have pedal spindles that you can fit your Shimano bodies to - if that is what you prefer.
@@BikePappy tbh, I currently struggle to find out which cleats i have :D
Just started 7 months ago, only used my roadbike with a smart trainer at home the first 5 month and I've never been on a group ride yet.
I googled the Look/KEO cleats and found mine advertised as SPD. I google for SPD and they look like the MTB cleats (I use 3 point roadbike cleats/shoes). That got me confused :(
Very nice looking bike 🤩🤩
That was a pretty big slam of Peloton you made there and frankly they deserve it.
That Canyon tho 👌
Thanks for viddeo, just what i needed!
But do i ride with 3 seconds average power or do i just set the zones. And do you use average normalized power after you are done training to find the zone you have trained in?
You ride with 3 sec average, raw numbers fluctuate way too much. You do not find the zone you have trained in by taking the average or anything else from an entire ride, for seeing in which zone you are training the same 3 sec average is the best measure too. On Strava for example you can then see for an entire ride how much time you have spent in which zone.
I suggest trying training peaks or todays plan as I find todays plan gives me more data
I usually ride a high cadence. I was mortified 😱. The first time I saw my power numbers.
In a good way or a bad way
@@gqh007 They were much lower than I thought it would be. I usually spun the 53-17 or 53-15 at 90rpm. I still do but I mix it up a lil more now.
High cadence wouldn’t lower power, it would lower torque. Riding at a high cadence is a good way to efficiently produce more power
@@MrLEGONATHAN Assuming you apply high torque as well as high rpm. Most people struggle to do this, the ability to do it is what separates the pros from everyone else.
@@Ed.R it’s like driving a car really: diesels produce more torque (force) than a petrol but at less RPMs for the same power. Petrols produce less torque but higher RPMS to produce the same power
Si is great at these
I would love a power metre just to see if the feeling of getting fitter actually translates to real number improvements. Unfortunately they are too expensive for my budget.
How do you like the Canyon bike?
I cant decide to buy a pedal or crank based powermeter :(
Crank if you can get one that fits. More protected from the road, and mechanically it is a better place for a strain gauge to take an accurate reading - reviews tend to say that crank is more accurate than pedal.
@@BC-wj8fx i should wait until i get a new bike i guess and do a bike fit before buying a power meter? Because it might be possible i need another crank length?
@@mikewow yes or you can replace just the crank set. There was no exact match for my power meter crank so I used the one with the nearest Q-factor and used some washers to shim the pedal out.
As a regular 59 year old rider using a 2011 Specialized Allez, a Power Meter is a NICE TO HAVE and expensive add-on to your machine. Since I only ride just for the sheer joy of riding (100 kms in 4 hours), I can put the cost of that add-on to something else....just my 2 cents....
Interesting title choice
I was just looking at power meter bundles. Specifically Garmin 850 bundle vs Wahoo. Great video!
Don’t get the garmin power pedals. Having those and nothing is about the same thing, they’re really inaccurate
Shoes look fast and powerful
I think we have to get a video about Si's gym routine 😂👏
which bike is he riding ? canyon aeroad ?
Gibt's sich Power Zentimeter?
Is there any word from shimano regarding the extensive crank failures on modern cranks? #askGCNtech
Also shimano has never been able to produce an accurate dual sided crank PM, is this generation any better? #askGCNtech
New generation cranks are symmetric which should have fixed the accuracy issues
Si will do anything to show off those bulging biceps😆. Great video by the way.
I just noticed that I always zeroed my PM in horizontal and not vertical haha
When he zeroed it, I was like: Is he doing it wrong or me the whole time?
My spider power meter (Quarq DZero) specifically said to zero it in the vertical position (drive-side crank at 6 o’clock). But fortunately it also auto-calibrates so I don’t do that often!
I would really like it if people on "social" group rides would just put their head units in their jersey pockets and download stuff when they get home. Between power obsessions and strava segments, I don't know how many friendly group rides have been ruined by " I've got to watch my numbers" or " sorry, I have to try for a PB on this segment."
So canyon gave that aeroad to gcn. Interesting
Nice to see a road bike again on GCN. It was turning into GGCN or something.
This one slipped through. Apologies - it won't happen again.
I love your eyebrows Si. Do you shape them?
1:48
Ouch.
Nice shoes!
it's all great ..great info video...but I certainly don't need a power meter to tell I'm getting dropped. 🤣
I find a power meter useful in stopping you getting dropped
If your pedal bearings are worn out or rough, will this affect your power meter readings?
no it will not affect the reading
