AeroCoach TT front light mounts

AeroCoach TT front light mounts come in three versions:

1. For Ascalons, an integrated computer/light mount which bolts to the side of the left hand Ascalon and replaces a normal Ascalon computer mount.

2. For Angles extensions or 22.2mm round extensions, an integrated computer/light mount which uses two zip ties to attach to the left hand extension. This mount comes with adapters for use with either Angles extensions (as the main body of the an Angles extension is elliptical) or 22.2mm round pole extensions, as well as wedges to change the angle of the mount.

3. For Angles extensions or 22.2mm round extensions, a standalone mount (without computer fitting) which can be placed anywhere on a 22.2mm round extension, or on the lower horizontal section of the Angles extension, which is 22.2mm round.

The mounts are made from sintered nylon, feature a round section 31.8mm in diameter and are compatible with a light which can be fitted to a standard road handlebar which uses a 31.8mm clamp. Please note there is a weight limit of 100g for a light fitted to the TT front light mount. Lights are not included.

When fitted with a bike computer and with rider on board, the integrated mounts give no aero penalty as long as the light does not extend below the mount. The standalone 22.2mm mount fitted with a light that does not extend below the mount results in a ~1w penalty. Having a light which extends below the mount results in a ~1.5w penalty depending on the shape of the light.

Light recommendations

Please note the dimensions of the light mount to ensure your light will fit. We recommend using a USB rechargeable light with a rubber band strap. The clamp section is ~23mm wide.
