Sometimes you just cant 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. The multi screw design allows for even loading and greater distribution of contact surface area on asymmetric or rounded dropouts such as those on BT's.
Two sizes are available - Standard or Large. Depending on your frameset one or the other might be better suited to your dropouts. The main difference between the standard and large is the adjustment length. The Large is thicker for increased strength.
- Sold individually (1 piece)
- Ultra thin profile for maximum axle nut thread engagement and minimal aero losses
- 2nd Generation design with improved stiffness and geometry for longer dropouts.
- 7075-T6 aluminium
- Hard anodized finish
- Suits 10mm axles
- Duel axle holes for greatest adjustability
- Surface grooves for axle nut bite
- Designed to work well with Runwell Elite Hub Nuts

A true attention to detail in this product. Excellent fit and finish. You can truly dial in the wheel alignment and chain tension and no more worrying about the wheel moving under load. Highly recommend as must get for any track bike user.
I’ve been using the short version of this tensioner on my Koga Kimera for 2 years now and I’m super happy about it’s durability and design, it’s 2 holes allow optimal axle positions according to the gear ratio.
Excellent finish and low profile make this a must-have for intense efforts while giving you peace of mind!
The perfect combination of this product with the Tacx Neo 2T Fixed-Gear Adapter saves me a lot of effort before training
