Sometimes you just can’t get enough bite on your axle nuts to stop the wheel from slipping. Velobike chain tensioners have been designed for best performance without compromising aerodynamics and performance.
Thinner than many other chain tensioners on the market, we developed these so that the axle nut maintains maximum thread engagement to limit axle thread damage. The low-profile design minimises aerodynamic losses around the nut and dropout area.
Two screws on the rear of the dropout can be tightened by hand or tightened with an allen key.
