Thinner than many other chain tensioners on the market, Velobike have 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.

Two colours available - black or silver grey (dubbed champagne money).

Hard anodized finish, 7000 series alumnium.

Suits 10mm axles.

Dual axle holes for greatest adjustability.

Surface grooves for axle nut bite.

Fits almost all horizontal dropouts including BT, Felt, Koga, Argon18, Cervelo, Dolan, Avanti, etc.
