I'm in the process of converting an old road bike to 1x7 and would like to shed my stem-mount shifter for a snazzy bar-mount one. The bulge on my bars is plenty wide enough to accommodate a shifter but I'm having trouble finding one that even comes close to having a 26mm clamp. Anyone here know of one or even a way to fabricate a clamp that will fit my bars? I'm aware of the Paul 'Thumbies' but they're so expensive......especially considering I'd only need one.
By the way, I'm using Shimano 7-speed indexed.
Thanks in advance!
