You may think im joking..................... http://www.pinkbike.com/photo/122082/ Mine lasted me 2 full years of hard riding, then i got my 1st orange zero which lasted me 51 weeks, just inside warranty Theyre worth nothing, impossible to dent, and when i switched to a zero i hardly felt any difference,So theyre really good for the bmx'y type street riding, they really arent worth much nowdays if you can find one, £20's a fair price for an ok one.
