Description

This CNC-machined aluminum alloy cycle chain tensioner features two pulley wheels. It is designed for riders seeking reliability in jumps, downhill tracks, and aggressive trail riding. Acting as a chain guide, it keeps the chain aligned and prevents drops on rough terrain. It allows conversion of a standard cycle frame with a derailleur hanger into a single-speed setup. The adjustable chainline and two pulley wheels ensure a fit. Compact dimensions: approximately 69 mm wide, 53 mm high, and 63 mm deep.
