YES I think this is the first time I have seen someone actually do the sit bone measurement properly i.e. actually on the saddle! Why have so many people spent so many years telling people to do this on the stairs or on a chair?
I appreciate you and your channel. I started waxing my chain and really enjoy the process. The Connex Link is a MUST…a true game changer. Thanks for all the tips. Now my New Year’s Resolution is to find carbon wheels that won’t require a 2nd mortgage. Grace & Peace!
I have been watching cycling/fit videos for 7 years (including this channel on occasion). This is the first time I saw someone taking seat bone measurements. I will definitely try this out.
a tip. if you have more than one saddle or intend to do this test, get extra seatposts so all you do is change the SP without having to re-do the measurements. of course there is the cost factor. up to you lol
It'd be really handy to rig up an Excel spreadsheet that did the math for you on the fly as you wanted to change things like reach/angle/etc. They are all related for sure, it'd be helpful to see it in the moment as you say want a new bike, or have integrated bars on one bike vs the other and are determining if you can make it work. Great tips in this video.
Since the shape of the seat is affects tilt measurements, probably would be better to reference tilt based on sit bone location. If your saddle doesn't have marks, either a marker line for reference or adding a small tape marker will make it easy to make small accurate moves or return to original position if needed. Same for stem / seat post changes. adding a small mark makes it easy to return if needed.
My advice try a narrow saddle and try a wide one and figure which is better for you. Personally I ride narrow saddle and I’ve never found a wide one that doesn’t give me saddle sores. I like the way you figured out sit bone width in the video but for me I just tried different saddles until I realized I’m in the skinny bones gang
Hi, Great video once again! I measured my bike, and by pure chance, my measurements are within a tolerance of 0 to -5mm. My body shape is quite similar to yours, but I weigh 91kg and have a slightly bigger belly. I'm 184cm tall with a leg length of 88cm, and my crank length is 170mm. Could you share your body measurements so we can get a better sense of whether my (or our) bike adjustments are approximately correct? Greetings from Germany!
Try the extremely expensive yet comfiest 3D printed Specialized Power Saddle, they even come with a 30 day money back comfortable warranty. Comfiest saddle I’ve ever used.
Great video, thanks. Wondering why you are measuring from the BB centre to sit bone, wouldn't it be better to measure from the peddle centre to sit bone and then take into account peddle centre to shoe?. As crank lengths vary. Or am I missing something?. Cheers
If you get a professional bike fit and make sure to take a measurement from the BB center, then you can easily transfer that to any bike. It isn’t any less accurate as long as you’re consistent and provided you keep the crank length and pedal/cleat setup consistent across your bikes
If you want to get picky, neither is technically correct. The pelvis is actually 3 bones fused together: the pubis, ilium and ischium. Many people colloquially use “pelvis” to refer specifically to the pubis. “Sit bones” is the colloquial term for the ischial tuberosities. I dare you to record a video where you say ischial tuberosities repeatedly.
Seems like a revisit of the "Ass-o-meter" gimmick I remember from awhile back. Didn't the Big-S have this thing in their dealerships? After having some "undercarriage" work done I found I couldn't sit comfortably on saddles I'd used for years (after plenty of trial and error) so in a panic raced off to my LBS. Sat on their Ass-o-meter, tried the models suggested and hated 'em all. Went through a bunch of makes/models after that, in increasing prices. Only found relief when I got to SMP and even with those it still took trial and error. Back-in-the-day the shop I worked at loaned saddles...there were only 3 - Rolls, Turbo or Regal. SMP has test centers that offer the same idea...only trial-and-error really works IMHO. Start with the thing dead-level (women usually like a slight downward angle) and spend some time riding 'em before moving on to another. When I switched out my road bikes for gravel bikes, the slightly more upright position changed weight distribution enough that I needed yet another change in saddle shape. Still SMP, but a bit wider and more padded in the back. Happy pedaling!
@@stevenleffanueAlex at Cycling Deal in Dandenong pranked me in 2020 , with an empty envelope . I will now have nothing to do with his team or recommend them .
I ride a CX bike, quite often over some very rough terrain, on a saddle that is generally comfortable. I have found that since buying the Redshift Shockstop seatpost, almost all the tenderness has gone. I think with such a seatpost most riders could tolerate even a very cheap saddle.
I've never understood why we measure seat height from the center of the crank axle. This doesn't take into account crank arm length. I use 160mm so my measurement would need to be 10mm shorter than someone using 170mm.
So quick questions. 1. Weight bearing capacity of the saddle. Do the saddles have and reference to this? I bought a Colnago and the saddle lasted 12 months or so before it cracked over a bump. It was a flexible seat but I was 84kg and apparently too heavy. 2. You didn't mention anything about saddle width. Your S saddle, I assume S for Specialised? It was the largest of the group you tested and mayhap the others were not wide enough? They looked narrower than the original, which might have meant you were sitting lower on the sides of the saddle than your original. 3. On replacing my saddle when the original went on the Colnago I went with a Fizzik. More your traditional materials over carbon, but that was because carbon was not that common at the time. Does carbon wear out more quickly because of fatigue from the flexing under the rider's weight and road surface impact?
The methods of measurement shown are fairly inaccurate esp the bar method for handlebar drop, because you are lying it along the saddle even the slightest change in saddle angle will create significant changes in the bar measurement. This will also not be reproducible with different saddles that may have different shapes for the same reason. I also consider handlebar drop a secondary measurement, it's a result of the primary measurements you should be taking and thus is relatively immaterial. Using a self-leveling laser level with X and Y beams centered on the bb is far superior and less prone to human error. You create coordinates for the hand and sit bone contact points relative to the constant location of the BB axis. For example the sit bone contact point might be 350mm(X) and 500mm(Y). While it's a slight bit more work to set up and ensuring the frame is level (using the laser to level the front and rear axles whilst in a stand works best for me) you get far more precision and repeatability across bikes and individual components. But I love the Al foil method for getting an accurate sit bone location. Nicely done on that.
The super team fizik Argo copy may be better run with some extra nose down. I have Argos on all my bikes and run the nose down a little due to the kick at the back. I know this is going to mess with your measurements though, almost looks like the nose it up in your vids.
I couldn't get comfy on it at all , best was with nose slightly up but still no good for me. If Argos fits you , you would probably find the copy works for you too.
Shouldn't adjust reach by adjusting saddle setback/offset. Pulling up when pedalling is not recommended, it's been shown to be inefficient and unneccessary. You didn't allow for saddle padding density/compressibility Pretty much impossible to adjust tilt by 1mm with most saddle rail clamps.
Most modern road bikes have micro-adjustable seat clamps now. Yes , saddle foam compression will generally affect height, but it's difficult to measure...if you suspect significant difference in padding compression between saddles you can take an educated guess.

Best is to measure the distance between sitbones and the hoods.
In the UK we are getting caked with mud...and you are just getting caked lol. Great video.

I'm so glad I MTB bike and just enjoy riding my bike. NERRRDS!
Hand numbing can also be caused by the seat sloping down which puts more weight on your hands
Oh yes, the legendary rider Wang Yoeleo.
@oz cycle what do you think of that Yoeleo? Decent road bike?
Thanks, good video. One question what is the brand of the bikestand (for the aft wheel)?
Not sure what brand but bought from local hardware store.

Yes, you can measure from centre of pedal spindle provided the crank is in line with the seat tube angle. Much easier from bb centre.

@@danielakerman8241 Thank you
Any particular reason why you are using the term "sit bone" and not pelvic bone?
Sit bone is commonly known , pelvic bone usually refers to the "girdle".
If you want to get picky, neither is technically correct. The pelvis is actually 3 bones fused together: the pubis, ilium and ischium. Many people colloquially use “pelvis” to refer specifically to the pubis. “Sit bones” is the colloquial term for the ischial tuberosities. I dare you to record a video where you say ischial tuberosities repeatedly.
Who cares ? 🤷🏼♂️
Your but will thank you
Nearly all bikefitters say sit bone , no need to get all fancy pants.

84kg should be fine on the majority of saddles.
All about the same width...141-143mm.

Semasi "arse heaven "
Clamp on the toptube while putting pressure on the bars. Sorry, but I'm not taking any advice from you
Not clamped, just sitting there....never clamp on carbon...even seatposts
@stevenleffanue don't put pressure on the bike when it's resting like that. That's exactly what clamping does.
It's not clamped
@@stevenleffanue it doesn't have to be. You're putting compressive load in a stress riser
