I rode to work today in the snow. This is the first time I've ridden in temps below 20F and snow. My stem has been torqued to spec and I rechecked it, but it keeps spinning on the steerer tube. It is a Bonty XXX carbon stem on a steel steerer tube. What can I do to make it stop. I don't want to over tighten the bolts and strip the threads or crack the stem. Can I just add a little Loctite to the stem/steerer interface? It is a little scary when even a small snow drift makes the handlebars go off center.
Not Loctite. Instead get some TACX Carbon Prep (AKA Tacx Dynamic Carbon Bicycle Assembly Compound).
Great stuff for carbon parts. Stopped my seat post from sliding down.
