I’m experiencing vibration somewhere in the rear half of the bicycle when descending at high speed (say more than 30 mph), and I haven’t been able to pinpoint the cause. Everything looks fine, everything I’ve tried wiggling seems solid, and nothing seems to be getting hot except the brakes and rim.
I’d like help figuring what, if anything is wrong.
I could try to describe my observations in more detail, though I hesitate to do so for two reasons. First, they are all fuzzy and potentially misleading, since it’s hard to examine the bicycle while it’s moving 30-40 mph, and it makes me nervous so I slow down and the vibration stops. Second, it seemed like it could be useful to have a checklist of things to look into when experiencing such vibration, that isn’t limited to my particular problem. (If it’s more appropriate for this community, I’ll edit this question to add my observations.)
