Could I get some biopace feedback? Would be much appreciated! Particularly: climbing, standing & sprinting, and maybe acceleration (from stop /or general).
Many thanks!
Biopace came with the mountain bike I bought in 1989. I do not notice any advantage or disadvantage in climbing, standing, sprinting or acceleration. I think it is very well made componentry, so there is no justification for removing it. I can't think of any good reason for avoiding it either.
