i have the short levers on my xt660x the cheap ones off ebay about �17 delivered from china. i have been using them on all my race bikes and have never had a problem with them at all and i ride hard on my bikes really late braking from high speeds on the race bikes. i use to by pazzo levers but as i change my bikes often it was cost an arm and a leg buy 3 or 4 sets a year.Anyway hope this helps.
