BOX one Chain tensioners

Manufactured in a very resistant 7075 aluminum, the BOX One chain tensioners are designed for wheels with 10mm axles 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.
