i'm having issues with my Brooks. I did some longer rides in LA and after about an hour it started getting uncomofortable. What i want to know is how long does it take to break this thing in? I've had it for a while and have put at least a thousand miles on this beast. Mostly frequent short rides, but what gives? Should i ditch it and call it quits? or should i expect to have something else for longer rides? It's the B17, it's made for long rides!
