I hop the Pinarello quite a bit. 25 year old Ultegra cranks are still fine. Wheels are doing well. Only rim I wasted while riding it was in a situation like caloso mentioned. I coulda saved it had I hopped that pothole. I didn't even see it, though I was getting sprayed my road mist from a passing 18-wheeler. Many road hazards don't even require an actual bunnyhop to get over, just a timely unweighting of the bike.
