I have a set of Nitto track bars that are 25.4mm diameter and need a stem to go with them.... I have been scoping old quill stems on Ebay and there are very few in that clamp size. Could I use a 3ttt stem with the 25.8mm clamp diameter? .4mm doesn't seem like it would be a problem but I don't want to buy one and be disappointed. My other options are to just go for a Nitto stem although they are expensive or get a 26mm stem and a Nitto shim.
Any help would be appreciated!
