Technical Q&A with Lennard Zinn: Component sizing; pedal overlap, wheelbuilding; aero’ lids; and crank design
Will a 31.7mm bar fit a 31.8mm stem?Dear Lennard,What do you think of using a 31.7 diameter road bar with a 31.8 stem? I'm under the impression that it is widely accepted to be okay. to use 25.8 diameter bars with 26.0 stems, and I do this on three of my bikes as I really like Deda bars, but prefer other stems. I would like to change one bike to a Thomson X4 stem and Deda oversize bars.Shane Dear Shane,The oversized handlebar diameter is done on an inch standard, namely 1-1/4”.
