Shave weight, go fast. BMX racing is easy. This Tangent Pivotal Seat and Post Combo is super lightweight and has absolutely no foam, no covering, and no comfort!. This bad boy ain't the seat to do the Tour de France on that's for sure, but you're not sitting down round the track are you? Hope not coz your mum is yelling PEDAL at you and if you don't, she's going to make you ride home. With no cool down seat!
