Brooks just came out with the B 68. It's the same size as the B 67, with no springs. I just ordered one from SpicerCycles.com. He said he didn't know the exact price yet, but would let me know Monday. He said it would be around a $100, but would give me a break on the price, so I said order it. It's pretty close to the same weight as the B 17. I'll update you on the price Monday
i got a b-68 from wallbike, it came just before christmas;
first put it on my winter/commuter bike (replacing a comfortable b-17) - a cross-check with albatross handlebars; rode it a 100km or so-couldn't find the right position. then i moved the b-68 to my mud bike - a trek 6500, seems to work well there or perhaps i'm just getting it broke in.
ps- my partner wants to put the b-68 on her bike, when she starts riding again after the temps get above freezing. we might have to get another b-68.
