Shimano roller brake hub

anyone have any experience with this hub? is it pretty effective for stopping, does it create any
"drag" on the wheels efficiency, and what's cassette will it accept 8 speed? TIA

Shimano Nexave? I have them on my TE-clone. They are as effective as my mechanical discbrakes were
and less adjustment needed. A little more work if you want to take the wheel off. No drag to speak
of AFAIK. Mine uses an eight speed Megarange cassette.

thanks Mikael, i haven't seen one in person, is there something that "wears out" like a brake does?

Does it work on any frame, or do you need to weld some kind of mounting hardware to the frame? If it
works on any frame it would be a good option for people who change wheel sizes.

I haven't looked but I assume it has two large brakeshoes inside. The ones on my Sturmey Archer hub
looks very durable.

They do need a grease refill at some point but I havent noticed any fade in mine after 8 months
without one.

I didn't need to weld anything. The rear came with mounting hardware for attaching it to the
rearstay. In front theres usually a little bracket welded on the fork but you can just use a loose
one that normally holds the brakearm on a bike with pedalbrakes on. (I can snap a pic or two if the
previous sentence made no sense ;-) )

I'm using the T400-series btw. I see that they have a new C500 series with a snazzier look and a
9-speed option now.

I have a 9-sp Megarange 11-34 on my Presto. Only ~100 miles on it so far. No noticeable drag.
Good, well-modulated stopping power. It's called a roller brake because internally it has rollers
spaced around an expanding cone/wedge. The rollers are forced out against the inside of the drum
by the wedge.
