Re: OK, i'm putting this out there, i'm likely to get toaste
I've run two generations of thumbies, one of gripshift and two or three of rapidfire. Ergonomically I love rapidfire. Shift up or down in a heartbeat. Finicky to get set up, but sometimes I think that's more due to the incessent need to add cogs to the rear. I love the simplicity and bombproofness of thumbshifters, but they are only really good at shifting in one direction. I loved the idea of gripshift ajnd its simplicity, but in practice I found the way it placed my wrist while riding uncomfortable. Having broken a wrist as a kid, it always made me leery while trail riding.
