Letras griegas Renthal Handlebar 7 8 Playbike 50cc Silver. The 7 8in handlebar that started the legacy of Renthal, created out of the necessity to produce a (7 8in 22. 2mm) dirtbike handlebar that could meet the demands of the world's best riders, the all aluminium 7 8in handlebar was born. Undergoing a 15 step advanced manufacturing process, using the same 7010 T6 aluminium found in Twinwall and Fatbar to reduce vibration transferred to the rider's hands. Combined with a crossbrace to improve stiffness for rider control, and coupled with patented crossbrace clamps, Renthal 7 8in bars provide riders with the perfect amount of flex while maintaining the strength to resist bending in the event of a crash.
