Question: How similar is this to the old Sachs version?  What RPM does it shift? Thinking of using this on a 20" folder.  The old hub could be tweaked inside.
Document: The shift point is controlled by the centrifugal force created by the rotational speed of the hub and it seems as if the hub I received was very well tuned for a 700c wheel. It DOES NOT shift too early for me! In fact, I have to crank my pedals pretty hard to activate the shift. By that time, this 57 year-old is getting a little winded.
I purchased this hub to keep my bike rolling with some gears and get rid of all the wires. I converted an old schwinn I bought for $20. The hub works great. It takes some getting used to, but once you do it's easy and fun to ride on. The hub shifts automatically when you reach a certain speed. I had to change out my chainring from a 54 to a 46t. It made a huge difference in being able to pedal.
The shift was perfect, very smooth and at the right speed for me and my setup. However, the brake still squeals as much as ever. I don't know if other hubs have this problem, or if there is something defective with mine. Maybe it the noise will stop once it's broken in. The noise while riding is very little, I can just barely hear the pawls ticking away.Overall this is a great hub and I might just get another one in case they stop making it.
The hub performs well, even without modification. However, I'm tired of manufactures selling unfinished products. There were no big surprises when I opened the box, however they should have included the strap for the brake arm and some technical info. The box contained the hub,dust cap, C-clip and 19t cog - nothing else. The strap was quickly acquired off an old kids bike I use for parts.
Not too big of a deal, and I already knew this from other reviews. SRAM help us out and give your customers what they need to turn this $75 hurricane-ready paper weight into something a bit more useful. Raise the price by a dollar to cover the extra expense of a sheet of paper and the strap kit.I built the hub up on a 26x1-3/8 rim, and put it all on a old 3-speed I rescued from the garbage.
Okay, first, it's noisy, the bearings are very loud, second, it auto-shifts TOO SOON, and there is no way to adjust it, there really is no reason for it to shift into the harder gear at 10mph, but since it does shift too soon and worse it shifts when I'm going UPHILL!
It's mooth, quiet, not too heavy, easy to build into a wheel and the brake is very effective and nicely progressive. Will try the non-brake version next.
No one who buys this hub cares about a few grams) and please publish some technical information.
Well, I ride a few times with this hub and I love it. Nothing bad to say about it. Like it a lot.
This hub was used successfully in a college project to design a four wheel motorised vehicle. The project received the fourth prize overall.
