Aero Chain Catcher

Aero Chain Catcher is available in two sizes – for 39-54 and 52-62 teeth chain rings used in a single ring set-up.  The narrow/wide teeth of our chain rings significantly reduce the risk of dropping the chain; however, on bumpy roads, there is still a chance that the chain can come off.

The Aero Chain Catcher runs with a small gap between the inside of the guide and the chain to deflect a jumping chain and send it back on the chainring rather than falling off and landing in the gap between your frame and chainset. This product is 3D printed in the UK and weighs in at just 40 grams (for the catcher used for larger rings). The catcher has multiple planes of adjustment to ensure perfect alignment with the chain and chainring.

Fitting and setup are fairly simple, with just a single bolt used to attach to the frame through the front mech bracket, and another single bolt for sideways adjustment.

The design incorporates a deep-section mounting boss and cap that help reduce aerodynamic drag around the exposed FD hanger, making the overall drag of the component neutral.

An aero profiled support crosses from the boss to the chainring guides, thus minimising frontal area and flow separation in the exposed region between the frame and chainring. The lateral position of the chainring guides is adjusted on a slide mechanism, thus enabling the width between the outer and inner to be reduced in order to provide better control of the chain and to minimise drag.

*** Please note that a single-speed chain, such as the SRAM X1, is also strongly advised when using a single ring.

*** This chain catcher is designed only for round rings; whilst it can be used with oval rings, it will not be as effective.
