Its probably the daily blast down 55th ave. Its 5% grade, so i hit around 35-40mph, and it has pot holes, that I don't always miss. I think the other problem is the cranking powe rI have. I've been bmx racing since I was 12 years old, and that sport is all about cranking power. I snap chains, i crush bottom brackets, and explode free hubs.
