Tubeless tyre inserts claim to offer additional protection for your mountain bike rim, so you can run lower tyre pressures for improved traction. The Rimpact Tyre Inserts are a relatively new option, so we got our local rim-dinger, David Hayward, to put them through the grinder as part of a tubeless insert group test. Over to David for the review.
We’re quite far into this tyre insert grouptest and I’m running out of things to say about foam. The smartly named Rimpact is another such foam tyre insert, with a bigger cross section than some, but a much lighter weight, coming in at just 89g per wheel. Plus 6g each end if you get Rimpact’s valves too.
Rimpact does a couple of different versions, and this is the downhill/enduro/trail option that’s designed for 2.3-2.6in wide tyres. Rimpact also does a wider version for plus tyres.
The inserts are only available in pairs, as Rimpact reckon you get maximum benefit from running them in both wheels at once due to the change in handling characteristics. They do however come in combos to suit pretty much every mountain bike, including mixed wheel sizes.

Why do you ask for registration to view some articles?
We get asked this a lot. The simple reason is that content is increasingly expensive to commission, create and publish and where once the cost of this process was mostly covered by advertising revenues, now that’s no longer the case. We increasingly rely on our paying members to keep Singletrack going and we’d love you to become one of our supporters. however, that’s not we are asking right now. You can read the rest of this feature simply by registering an account on our site.
How does being a free, registered user help you?
A good question and it’s a bit complicated. It’s NOT so we can sell your email details, or even to send you newsletters. Our last newsletter was sent out in early 2018 – we really should send out a few. It’s not so we can show you more ads either – in fact when you register we show you fewer ads. The reason is actually because registered users come back and look at more of our content. They start interacting with us and posting comments of their own and joining in forum discussion. That level of interaction is what eventually feeds our new subscriber numbers and so for us the journey to gaining new subscribers is to start by encouraging you to simply register an account. We hope that the benefits that will bring to you will be the first step in you joining us as a paying Singletrack Premier supporter.
