PRO CX Tyre Insert Kit 700C x 33c - 45c with Valves
Let every ride be Epic!
Rimpact Pro CX tyre inserts are designed for Cyclo-Cross racing and Gravel Riding giving you the confidence to ride hard all day without damaging your rims or getting a flat. At 55grams the Pro CX insert adds minimal weight to the wheel.
How is this possible? Rimpact is inserted into the inner core of the tyre, providing a cushioning layer that absorbs impacts to protect the rim, while stabilising the tyre sidewall minimising tyre roll and burping. Allowing you to run lower tyre pressures, permitting the tyre to efficiently conform to trail obstacles increasing traction, while dampening trail vibrations that lead to forearm pump, and reducing the ability for objects to penetrate the tyre causing a flat.
Rimpact inserts are an engineered bike tyre insert manufactured from high density, closed cell and cross-linked polyethylene foam coupled with an Energy Sensitive outer layer. The result is a lightweight, highly impact absorbent foam insert for tubeless gravel bike tyres providing the following benefits:
- Dissipates force away from the rim
- Controls rebound increasing traction
- Stabilises sidewalls – reduced tyre roll/burping
- Makes lower tyre pressures viable
- Dramatically reduces trail chatter
The Energy Sensitive layer hardens on impact and dissipates extreme forces across itself and the foam below rather than into the rim. Making this Rimpacts most protective insert, perfect for those that want to push the envelope on every ride.
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.
Suitable for UCI spec CX tyres (33c) but compatible with any rim with an inner diameter of 17mm - 25mm and tyre widths 33c to 45c. Do not purchase if your rims are outside of this spec. Not compatible with hook less rims.
