Tubeless inserts reduce wheel damage and improve the feel of your bike. For a long time Cushcore ruled the insert market and none of the cheaper options had decent performance, but Rimpact has changed that. Rimpact are simply a well-performing product at a better price-point than the alternatives.

This listing is for a set (two) of inserts with valves. Please consult the rim width diagram at the end of this listing to determine whether this particular product is appropriate for your bike.

Rimpact Tubeless Inserts help in the following ways:

1. They minimise the impact force on your rim. We’ve had far less rim dings since riding them.
2. They help stabilise your tyre sidewall. The level of stabilisation will depend on the combination of rim and tyre that you are running.
3. They reduce trail chatter. The extent to which they do this surprised us but it was very welcome 😊
4. They reduce the chances of damaging your tyre.

In late 2022 Rimpact released an update to their inserts (hence V2) which changed the shape slightly to better fit modern rims. They also released some new insert models. We carry all Rimpact models and sell combinations of them so you can mix and match to get your ideal setup. If you're curious about other Rimpact models you can see all of our listings here.

Original, and gravel/xc, inserts are made of a single type of foam and provide great performance at a great price point. We ran Original inserts very happily for 6 months at the Christchurch Adventure Park and were very happy with their performance.

Pro, and cx, inserts are made from a dual-density foam which provides even more rim protection, tyre stability and tyre damage prevention than the original inserts.

EDH inserts also have a dual compound like the PRO model but the outer layer is even more supportive and protective. This is the highest protection model and is best suited for serious downhill riders and for heavy e-bikes. Note that installing the EDH in a 2.4” tyre is quite a strength and patience requiring process.

Our experience using Rimpact
After a number of years on Rimpact on our gravity bikes we’ve found our favourite front insert to be the Original model because it has the best vibration damping characteristics and lowest weight. On the rear we prefer the heaviest duty model we can afford/be bothered installing, whether that be a Pro or EDH model.

We’ve not tried the XC/Gravel model but have been running the CX model for years. We’ve been impressed by how much smoother it makes our gravel bikes ride and blown away by how much traction we can get at cyclocross races when we drop the tyre pressures to 25psi (and don’t have any issues!).

 Notes

A note about sealant: Tyre inserts will significantly increase the surface area inside your tyre so we suggest using 30% or so extra sealant than you would usually.

If you've got this far, we may also have some clearance stock of old V1 rimpact models. It would be worth having a look as they will be at a discount.
