MTB Insert Size Guide

Head to our Size Guide page for an in-depth guide on selecting the correct Insert for your Bike. Below is a brief break down on how to choose your insert based on discipline.

Please note at present some sizes aren't available in the PRO model. All sizes are available in the ORIGINAL variation. If you can't find what you need, get in touch as we can make custom sets in the ORIGINAL design!



Or if you are light weight:

Rimpact ORIGINAL is the best option for you. The inserts' light weight and trail chatter absorbing characteristics make it the best choice. You may also want to choose this option if you are a particularly smooth rider who doesn't ever have issues with punctures but rides in more demanding disciplines. 


All Mountain/Enduro

Or If you are of average weight:

Rimpact ORIGINAL or PRO will work great for you. Both will protect you, but the PRO will give you more insurance when you roll the dice. If you don't suffer from Rim Dings or Flats and are only looking for the damping characteristics, go for the ORIGINAL. If you race against the clock or push the envelope, the PRO version is for you.


Enduro Race/DH

Or if you are a Heavy Weight:

Rimpact PRO is your poison.  Maximum protection against spontaneous tyre deflation. For those who close their eyes when they send it, zero compromises on performance. If you take the fastest line no matter the consequences and lay it all out on race day, or need to lay off the Christmas Dinners, Rimpact PRO should keep your rims circular.
