upgrade your road bike with 31.8mm stem to use aerobar extensions.
Two clamps are placed either side of the stem on a 31.8mm round section of the handlebar, with the ability to increase stack in 10mm increments using optional spacers. Using our pole clamp on top you can mount Angles extensions and Align Wing arm rests, or an industry standard 22.2mm extension.
Extension angle can be adjusted by rotating the clamp around the 31.8mm handlebar - optional Angles extensions can also be purchased in 25deg, 35deg or 45deg.
The external width of each 31.8mm clamp is 17mm - you must ensure there is adequate 31.8mm round section either side of your stem for the clamps to fit. We recommend a minimum of 90mm width of 31.8mm round section including the stem clamp area.

ANGLES CARBON EXTENSIONS
The AeroCoach extension clamps are designed to work with any industry-standard 22.2mm diameter extensions, including our Angles carbon extensions. For details of Angles carbon extensions, please see HERE.
The AeroCoach Garmin or Wahoo computer mounts are designed to fit the elliptical cross section of our Angles carbon extensions, as well as coming with an adapter for use with normal round 22.2mm extensions. There is also an additional shim included to help tilt the GPS computer when using Angles extensions that have been adjusted inwards.
Each mount comes with a round adapter, tilt shim and two cable ties.
