Hi,
I hope it's OK to ask a question in this thread with that many great conversions. I own a 1995 MTB with a 12cm (or even 14cm?) flat stem and a flat handle bar. I also have twist shifters and although I never liked them when I was young I'm now quite happy with them.
If I'm going to replace my current handle bar with one with a back sweep (15-30°) can I keep my twist shifters you do I need thumb or trigger shifters?
