it would be for a bridgestone mb-4. I need more hand position, flat bars are hurting my wrists. also I think it would give me the ability to stretch out more. I was looking at drop bars, but that requires a big investment and id have to change too much stuff, and I dont really like the butterfly bars since it looks like it would cramp me even more and they look goofy. I like the gary bars, but it looks like itd have the same expenses as normal drop bars would have.
