I have just received my adapter kit, so I can finally install my Classified powershift hub on my road bike, together with a massive 58t ring for optimal speed efficiency
Hi Ronald, I love your videos but this one have the wrong title. The Ultimate In Efficiency, this unit lowers your efficiency - every review all over the internet states this. You should of just called it The Ultimate In Range which would be absolutely true. Good luck :)
Totally agree. It is definitely not the ultimate in efficiency. No mention of the extra weight either. Sure no chain drops, but who actually has a problem with chain drops anyway??? I ride 20k km every year and have maybe one chain drop per year....if that!
@ronykuba yep, lots of people in the comments are rightly calling BS on this one. If it was the ultimate in efficiency as you claim, then the world tour teams would be rapidly switching to Classified hubs. But they are not. Aside from a couple of riders trying it briefly last year, nobody in the WT is racing with it. NOBODY! So much for ultimate efficiency. If we all misunderstood your point, maybe you should have explained it better. You are the Classified sponsored guy, surely you should be able to give us proper explanations???
@@CG-99 yes because WT teams are known for their flexibility when it comes to adopting new technologies… As for the explanation - you are right, it probably needs more in that field. A topic for a future video for sure.
I didn't understand the gearing ratio. If the 58T gives you 40T with the decoupling, that's 1.45 ratio. Is that it? How to they communicate about that? It's basically the most important thing but you barely touched on it. Do we know how efficient it is? A 2x setup has worked forever, especially if you don't cross chain. You have a chain catcher so the aero benefits are questionable. A big ring is more efficient than a small one, but does that more than offset the losses of the hubs?
No, that’s wrong. The ratio is 0.67. 58x0.67 = 38.86 (so 39t virtual actually, my bad). Yes, there’s a lot of testing and a full white paper on the efficiency, as you would expect with such a product. It’s an aerocoach aero chain catcher - faster than a frame with the FD hanger just sticking out in the wind, and significantly faster than 2x. There’s no loss in the 1:1 ratio (used most of the time). For the rest, yes it does offset the difference.
I have the classified system and one thing I am sure is that it's not any slower than my 2x bikes. If anything I am probably faster on the descent and flats. I don't see the speed difference on a climb either. Sure you would lose the efficiency when you go 20mph on a climb and in the small gear ratio but when you are smart you shift your gears and not talk shit about things that you never used before.
It is a great idea and I can not understand why it is not widely used in the industry. I was riding Sturmey-Archer CS-RK3 (3 internal gears and HG Freehub Bodie) but in my opinion, 2 internal gears are the optimal solution. I hope that you will be satisfied with HOPE :).
Not yet, but they’re pushing for mass adoption. It will be difficult to compete with the pressure of the 2 drivetrain giants. Oh yes, I love the Hope rotors!
