Rimpact Tire Insert and Valve

Rimpact is a foam insert that hugs your wheels and absorbs square edge hits so your rims don't have to.

Rimpact is made from a high density, closed-cell, cross-linked polyethylene foam used in both the electronics and medical fields.

Suitable for rims with an inner diameter of 23mm - 35mm and tire widths 2.3"-2.6". 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. The 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 tire.

Weight: Approx. 95g per insert for 29", 90g approx for 27.5"

Why Use Rimpact’s?

Increased Tire Stability

By acting as a support for the tire sidewalls as well as a dampener system, Rimpact improves tire stability over conventional undamped air.

Reduce Tire Roll

Typically riders struggle to find the balance between grip and tire stability. With Rimpact there is no longer a trade-off thanks to the support it provides.

Make Lower Pressures Viable

Historically running lower pressures required the rider to ride smooth or risk flatting, burping or rolling the tire. Think of Rimpact as a ‘volume token’ and ‘bottom out bumper’ combined. Increased ramp up with added bottom-out resistance makes those lower pressures viable again.

Reduce Trail Chatter

The best reason to run Rimpact? Reduced trail chatter. Rimpact acts as a deadening device for your highly-strung rims, making the ride smoother. When you ride smooth, you go fast!
