Thats what im thinking right now, current 26.4 post is pretty loose, needs alot of tightening and falls freely into the tube when u give it freedom
capiler shows 26.5mm but slot is still pinched a bit, id assume 26.6 will fit perfectly
And yes u are absolutely right about CROMOR, the butting is on the bottom bracket side, thanks for help T-Mar!
