Yeah I suspect you're right as I've had issues on a wide variety of tyre combinations and I get the same discomfort when abroad on much smoother roads ( I live in the UK)TobinHatesYou wrote:I very much doubt it's road vibration or bumpy terrain. The spring analogy I made earlier still applies. Your spine is like a damper everything attached to it. This is almost certainly a conditioning issue or fit issue, not overinflated tires or a hard saddle or anything like that.
Should I be aiming for a flat spine on a side profile?
It would be interesting to hear from anyone else that is a similar height and what size bike they ride too?
