Offering excellent value for money, chain tensioners are designed for wheels with 10mm axle and for classic frame dropouts. They prevent derailment during your acceleration during BMX races. The 2 fixing holes and the tension adjustment by screw allow you an even more precise adjustment of the chain tension thanks to the control marks.
