That is a pretty one. Sounds promising.

Coaster brakes have have an arm that is attached to a band that wraps around the chainstay. A Carbon Fiber bike isn't designed to have anything exerting a load on the chainstay other than those found in normal riding. The band would cause a crack possibly resulting in a catastrophic frame failure. It's the same reason why you wouldn't install a kickstand on a CF bike. http://img6.exs.cx/img6/8897/doh.gif

Very cool, very cool indeed. As soon as things get rolling let me know if you want any pre-orders or anything to help defray the initial cost. I also think that coaster brakes are the wave of the future.

This thread has inspired me quite a bit. I'm going to get a road bike frame and build new 700c's for it with a drum brake front, and coaster rear, single speed, no derailer or tensioner if I can help it.

No shifters, only one brake handle, maybe none if i can try it w/o the front brake, just to see. Ultimate in simplicity and should be lighter too :D

This one weighs about a kilo. Having said that, my Steamroller still weighs only 20.5 lbs with one. I think that's pretty good.

Everything you say is true .... I guess it's time for those CF manufacturers to rethink their designs .... Yike!

Shimano's E-type coaster brake can take one hell of a beating. The failures I have with my rental fleet have more to do with exposure to salt water or a lack of grease at manufactuer.

I may be willing to pre-order one, too. What kind of price are you thinking of?

That's one of the things we haven't worked out yet. That is, one of their 'lost' emails may have had that information but as it stands ... I don't know. I'll let everyone know as soon as I do. I'm glad to hear the interest though ;-)
