Sponsorships are a big misty cloud covering like 90% of content, that and shitty videos from big mtb channels claiming components making them go 5 second faster/slower down a trail they ride twice for comparison. Lol... cough'cough gmbn cough
Hahaha, well thank you for the praise, although I will point out that our "Sprag" character is a parody of The Top Gear's "The Stig." Nothing new under the sun! We're big fans though, figured it would be fun to do an homage to that. Cheers, Dan P.
Love it. Can't say I am as surprised: faster engagement means more pawl surface area, usually. This will always (?) increase drag. Or so it seemed to me. Still, I love this kind of thing and I appreciate all the work to test!
Pretty much what I expected, the drag from a hub is so insignificant compared to the drag from wind resistance, tyres would make much more difference than a hub.
There's a shop in England that knows a great mod for the Hope hub engagement to give it even more than originally comes with! His videos on UA-cam showing some of how he does it for us! Loads go to him to get it done to make the hubs even better! The engagement springs are stiffened up and 2 of the tabs are cut down so it's 2 and 2 first 2 fins grips then the next 2 grip so all 4 don't grip at same time this gives it alot more points of engagement. And proved it's not the size of the spring but the tension of the spring that makes it better! And why we all go to him with our hope hubs
is it possible that the tires rolling resistance could affect the results ... also the tire temp affecting the firmness of the knobs from morning to evening
Good question. Someone else also mentioned the temperature and therefore hardness of the asphalt. I'm sure those would make a difference, I have no idea how much though. Probably not enough to become apparent when you're only doing three trials of each hub. - Dan P.
I think you must mean The Stig's trail shredding cousin. Great video, with good info. I bought some Pro 5 hubs in silver, just waiting for DT Swiss FR541 in 28 hole format to become available before I build them up. If you could do a cost conscious build your own wheel video, that would be great. Including for example, which wheel stand represents the best value for money. Thanks anyway for the fun video, new sub.
I would have liked to seen another test where the chain was removed for both wheel combos- this would have taken a look at whether the larger bearings in the hope 5 made the difference. I suspect that the combo of the larger bearings (with more drag) and the new seals (less drag) the net result is basically the same.
OK. Stopping to comment at 11:41. Similar distances but one is faster.... The tires (tyres) have a fixed amount of rolling resistance on that surface. The fact that the speeds vary would indicate a faster variable somewhere - if the hub is the only change, that has to be it. So - Hope 5 is faster than Hope 4, BUT that is not more impactful than a tire that rolls with less resistance per surface. I'd like to have seen a test with a tubeless wheel at the same inflation. Good tubeless plus Hope 5 = dangerously fast and sexy sounding.
Front rotor could be the one dragging (if at all) but it’s a wash at result time. As you mentioned, this isn’t science per say, but scientific enough to apply to average trail riding and if/how long hub drag is affecting wheel rotation. Spend the majority of your time single speeding on trails and this is practical information. You coast and carry speed more and no matter who argues that you’re imagining it, drag is perceptible in this exact manner of coasting.
When it comes to racing 6ft in seconds is a massive margin! Thats a Massive difference you should have timed them aswell but as I said the new engagement is rusting fast and seizing up just now
I have Hope Pro 4/ XM481 on one bike and Hyrday/Trail 270 on another bike... One wheelset is heavier and less drag, less engagement... and the other is the opposite at 1650 g and 690 POE.... I love the test completed here... I wonder if it could have been better or more pronounced if the bike was up to a higher speed for longer.... maybe that's when drag really starts trimming time via summation of high speed revolutions and incremental inputs of drag added up
I think a electric pressure gauge is crucial in this kind of test. even 1psi - 2psi will midigate any measureble difference in hub drag. Also, the results are so close and the sample size is very low...could've easily been caused by slightly different rider positions and hence aerodynamic drag
@@trentvlak there is no contact when coasting, it does not have poles rather wedges than engage when you pedal. the only contact there is comes from the bearing 9i think) they use which you cant really beat
I appreciate what you did here. However, Im amazed when a sponsor's product doesn't perform, or at least doesn't perform better suddenly the test you performed is under question. "The results weren't what we would have expected ... So here's 10 things wrong with what we did". In actuality I'm sure hope hubs are perfectly good hubs, new version or old. I also suspect that the drag from a quality hub has about zero impact on a typical mountain bike.
Good call, we wondered about that. One thing I learned a while back is that asphalt can actually creep down a steep enough slope over time, which is why really steep roads tend to be made of concrete. Wild. - Dan P.
My suspicion is that you'd be fine, but I'd say shoot Hope a message with a description of your situation (bike model, body weight, usage) and see what they think. You can reach them at service@hopetech.com Cheers, Dan P.
The best way to reduce drag in a rear hub (or other moving parts) is to remove all the bearing seals and flush out all the grease. Don't put the seals back on again, just ride it like that. IRL however, unless you have a race mechanic at your disposal who'll rebuild your bike every ride, its nice to have seals and grease in fact I'd rather have well sealed bearings than tiny improvements in rolling resistance that you won't notice as soon as your tyres are dirty, let alone if the wind blows!!!.
yep, pop off the seals, put in a light lube. for mountain biking though you may not even make it 1 ride before it ends up slower. good trick for a road TT though
@@JackMott You're 100% correct for XC and enduro racing but the bigger downhill teams certainly do it for the final race run,(s), usually about 4 minutes long, probably not for training or practice though.
Hope 5 pro hubs are rusting up quick in the engagement teeth! One my mates cassette is seized on to the outter casing! Something in the metals been changed I've ran hope for donkies years never seen this!
Fancy bearings vs regular bearings are less than 1 watt difference when under load. And the fancy ones require more maintenance as that 0.3 watts is gained by having less sealy seals and or lighter lubricants. Impossible to measure outside of a velodrome.
The new, wider bearing on the Pro 5 driver is just an Enduro bearing #15267. The one on the Pro 4 is #6803. They are, respectively, 5x26x7mm in the Pro 5, 17x26x5mm in the Pro 4. You should be able to find both of them easily. - Dan P.
@@janeblogs324 Right you are, sorry for my naiveté. Those are bearings that we around the shop, so in my head I wasn't thinking of them as hard-to-find. Now that I look though, I realize we don't even have them listed online. I'll see if we can get them up. - Dan P.
Have been running pro 4 hubs for almost five years and there good but not great the company is great , best things are easy to work on and good bearings ie skf are available the hope bearings are just shit chinese stainless crap , The other shit thing is that green thing they call a seal i file mine out and sand it thinner so there is no drag thats how you make them faster . And sorry sram but the xd driver idea is just plain dumb i will be sticking with hg freehub bodies and lastly the alloy freehub body is as strong as firm butter from the fridge go steel or stay home so i will still be using my pro 4 for while longer oh lastly they need to make the drive ring in the hub body replaceable . Still like them hope .
I got some of the cheapest hubs ever. They don’t roll more than 3 turns when I spin my wheel slightly and also some of the balls of one of the rear hub bearings literally got cut in half
No one's rolling hill and looking for distance. I myself are a fan of hydras, but looking at the onyx vespers. Not enough difference to make a legit decision on a brand.
In our country, we have an actor - Ondrej Brzobohaty - and he is Drag Queen. And like a lot, you can google it, its completely twisted even he keeps saying it has no influence on his sexuality. Anyway, do you think it makes him slower then? Thanks for reply!
Who? Most bikers are already at their minimum weight. If they're talking about making their bike lighter then they obviously can't make their body any lighter.
I used to work in a bike shop in Redding, California called Sports LTD, and us bike mechanics would weigh ourselves before we went and took a dump. We lost around 4 or 5 pounds just by dropping a deuce in the porcelain bowl.
I enjoy how this takes a different approach to bike videos. I'm so over vloggers saying "yo this sponsored product is sick"

You did a great job 👍 nothing is perfect going for a cycle.
Have definitely taken the place off pinkbike since Levy has been missing.
well done video. great explanation of the hubs.
Great vlog very interesting.
Just had new hope headset fitted to cheap bike & very happy 😊 hope legendary quality 👌 👏 😊
Bike Nerdery, heart you.
If it want loud pawls just take all the grease out of the pawl area. It's simple and doesn't hurt anything.
I prefer a loud hub, it's a natural bell.
Top Gear would like a word lol

Yes but then the free hub wouldn’t be held in place anymore if you removed the chain. There by negating any affect the Pawls have on drag.
time to compare drag of all hubs (onyx, Chris King, Hydra)
: )
I have hydras, and while it's impossible for me to test. In my mind, they seam like a very draggy hub
Onyx will win

Have you compared the Onyx Classic MTB hub ... sprag clutch and better bearings ? Supposedly less drag ! Would be interesting
I own the Pro 4 SS/T hubs and was wondering if the new Pro 5 Trial rear hub has wider spaced flanges, longer hub shell?
When it comes to racing 6ft in seconds is a massive margin! Thats a Massive difference you should have timed them aswell but as I said the new engagement is rusting fast and seizing up just now

Load can change drag. Seals, bearings, etc.

No. I think the silence gives the illusion of low drag.

Great video however hubs are not the only concern IMO for resistance, I would mention caliper alignment and rotors.
8:59 I don't understand the math here. If 2 at a time engage and the total is 6, then there must be 3 pairs. If 3 pairs engage 3x54 = 162 ?
Ooo yep good catch, I misspoke. Three at a time, so two "phases." Then the rest adds up if you correct that, 2x54=108.
Sorry, and thanks!

You also need to consider rider weight decreasing throughout the test.

That's a Transition Patrol, and that is The Sprag!

You'd probably find more with road tires. Very likely the rolling resistance of those tires are covering up any gains from the hub
Fancy bearings vs regular bearings are less than 1 watt difference when under load. And the fancy ones require more maintenance as that 0.3 watts is gained by having less sealy seals and or lighter lubricants. Impossible to measure outside of a velodrome.
No Onyx eh? Amusing no inter brand comparison? Love to see Onyx vs Shimano vs Industry Nine
Seriously. Onyx is being slept on.
Love my onyx. And the silence.
this video is isolating essentially just drag. The onyx is a completely different hub, wheres as the pro 5 is more like just a new iteration
More sprag
Regardless of the HUB & its pawl engagement, I have found Kogel ceramic bearings improve speed, reduce drag, and make most wheels better.
Of course, you paid for it. How much faster are you now? 0,00…kph?
High precision hubs make more sense on a HT.
❤
as an owner of the new pro5 they are smooth and rolls very long compared to my DT.
Like others have said, now compare to Onyx. Especially when you're test rider is named "Sprag".
Good catch on the test rider's name ;)
Drag is something Onyx does tout. Might have to make that happen!
