25.4 mm butterfly handlebar on vintage 26mm single bolt quil stem
I have a vintage 94 Trek Antelope 820, I want to change the handlebar to put on the butterfly style as i can use the existing break and gear shifter....(i had wanted a bullhorn, but that turned out to be too much trouble)
There is about a quarter inch gap in the clamp when the current 26mm handlebar is installed, does that mean i should be able to tighten the bolt on the 25.4 mm bar?
Could i cut out a soda/beer can shim as the diff between 25.4 and 26 is not that great? Or is it better to do without the shim if it tightens?
(i know i should get a specialized shim but im not wanting to invest that on this beater bike)
Your input would be greatly appreciated, im adding a picture of my clamp to this post!
