XC/Gravel Tyre Insert Kit with Valves

Designed for Gravel Riding or XC Racing. Rimpact Gravel/XC will solve the issue of having to run thin and light tyres at lower pressure whilst also trying to maintain rolling speed and puncture resistance. By allowing you to run lower pressures to gain more traction whilst retaining bottom out resistance you can push as hard as you can on the track or in the back country without fear.

Suitable for but compatible with any rim with an inner diameter between 20mm - 30mm and tyre widths 40c -55c or 1.5"-2.35". (Keep in mind that the difficulty of fitting increases dramatically the narrower your rims and tyres are). Insert is available in 27.5"/650b, 700c/29".

Rimpact inserts are an engineered bike tyre insert manufactured from high density, closed cell and cross-linked polyethylene foam used in the aerospace industry. The result is a lightweight, highly impact absorbent foam insert for tubeless Gravel/XC bike tyres that provide the following benefits:

- Dissipates force away from the rim
- Controls rebound increasing traction
- Stabilises sidewalls – reduced tyre roll/burping
- Makes Lower pressures viable
- Dramatically reduces trail chatter

The kit comes with two un-blockable presta valves made of CNC'd aluminium with horizontal air ports. This design ensures the valve will not block even if the insert shifts. They work with sealant injectors, have removable cores and can be run in a regular tubeless setup.

Hookless Rims are compatible but if you run close to min or max pressures recommended by the rim and tyre manufacturer, the rim will struggle to hold the tyre in place due to the hookless design. For more info please get in touch.

Weight: approx. 70g per insert

To install Rimpact Inserts you will have to convert the the tyre to a tubeless system if you have not already done so.  We recommend Stans NoTubes sealant and rim tape.
