Please note we do not fit oval basebars.

If your basebars don’t match, please size up to the nearest half. i.e. if your bar measures 23.7mm, please select 24mm.

If your bike is not on that list, please measure your basebar with one of the following methods:

  1. Use a Vernier Calliper to measure the outside diameter of your base bars. Please check multiple points along the basebar grip area to ensure your basebars are not oval.
  2. If you do not have a vernier calliper, measure the outside circumference of the basebar with a tape measure, then use the table below to identify which grip you need.
Circumference of basebar: Base bar grip size:
71.3 mm 22.7 mm
75.4 mm 24 mm
78.5 mm 25 mm
