Well, I have never actually had a major crash like that. However, the fastest that I was rolling that I ALMOST had a crash was 89km/h. This also happens to be my fastest speed ever. I had a 30km tail wind and I was going down a 24% hill. I was more scared of frying the bearings in my hubs at 90km/h. Luckily, I had just greased them 24hours prior to the ride. BIking back up the hill was a b****.
