Rimpact CX Tyre Inserts

Contents Per Pack:
2 x CX Tyre Inserts
2 x 44mm Rimpact Unblockable Valves or Peaty's Valves (black)

Designed for Cyclo-Cross racing and Gravel Riding. Rimpact CX is Rimpact's lightest insert at 55 grams, under HALF the weight of the competition.

Just like the Rimpact PRO, it utilises an Energy Sensitive layer mated with Rimpact ORIGINAL Foam that hardens on impact and dissipates extreme forces across itself and the foam below rather than into the rim. The material remains supple and malleable meaning its easy to install and not harsh to ride on, yet when it counts, Rimpact steps it up to maximum protection mode and allows you to ride it out when there's no easy line choice! Read more about the PRO here.

Rimpact CX lets you run lower pressures on clincher tyres to gain more traction and level the playing field against tubular tyres!

Please Note: There is a 'No Valves Required' product option available in the drop down menu that ships without valves for those who are replacing a set of inserts and already own a pair of Rimpact Unblockable Valves. Rimpact must be used in conjunction to our valve design, or a Insert specific valves such as Peaty's MK2 valves. If Peaty's Valves are selected, please indicate your colour choice in the 'add notes' box at checkout. Colour choices are Bourbon, Turquoise, Violet, Mango, Silver, Navy, Matte Slate, Matte Emerald, Matte Punch, Red and Gold (not pictured).

Suitable for UCI regulation spec CX tyres (33c) but compatible with any rim with an inner diameter of 17mm - 25mm and tyre widths 33c to 45c. (Keep in mind that the difficulty of fitting increases dramatically the narrower your rims are). The diameter is 700c. Do not purchase if your rims are out side of this spec. Running 650b? Currently we don't have an insert for your wheels, but are looking to get one into production and very soon, keep an eye on our social media for more details for the launch! Hookless Rims may not be compatible if you run close to min or max pressures recommended by the rim and tyre manufacturer. For more info please get in touch.

Use about 25% more sealant than recommended on the bottle to ensure the extra surface area of the insert is coated with plenty of fluid to spare. Our inserts are closed cell and cannot absorb liquid however some sealant will cling to the outside of the insert requiring a slightly higher dosage. It can be injected through Rimpact Valves or poured directly into the tyre.

Weight: approx. 55g per insert.

Disclaimer: It is not advised to run air pressures outside that of the tyre manufacturers recommendations. Failure to do so may result in injury or the premature failure of the bicycle. Rimpact does not accept any responsibility for misuse of the Rimpact insert or improper installation. Rimpact Inserts are designed to work WITH Rimpact unblockable valves. Not included: Tyres, Wheelset.
