We offer the Reverb AXS B1/B2 in three diameters (30.9mm, 31.6mm, and 34.9mm), with travel lengths ranging from 100mm to 250mm. Below are the relevant fitment dimensions for each diameter and travel option. Remember, Maximum Insertion Depth is specific to each frame; please ensure proper insertion depth and seat height before ordering. If you are between sizes, we strongly recommend the shorter travel option to make sure it's a good fit.
You can also check your work against the recommendation of our Reverb AXS B1/B2 calculator.
Measure twice, order once.
