Big Yellow Insert

Rockstop Rim Protector is a removable, easy to fit, impact protection product for your MTB & EMTB

Technology

Tough & Flexible

Our Rim Protector is made from a tough Polyurethane blown Elastomer. In simple terms it's a tough, highly shock absorbing rubberised polymer. Polyurethane Elastomer is often used in shock absorbers in F1 cars and aerospace industries.

Low Profile

Using a high density shock absorbing material that takes up a fraction of the space in your tyre, lasts longer and doesn't affect the air pressure dynamics as much. The benefit of this is you can set up your tyres how you like them and you won't even notice they're in there!

Run Low PSI

You can be more confident in cornering under low pressure because the edges of the Rockstop Rim Protector push into the side walls of your tyre keeping it seated. It also gives a little more of a firm feeling on the side walls of the tyre in the bottom third as it approaches the rim. This stops the tyre feeling “squirrely” at lower pressures when you’re cornering.

Smart Geometry

The holes do 2 things, they allow the sealant to flow through the wheel quickly so it doesn't get blocked and become ineffective and it also keeps the weight of the insert down. The raised cross bridges either side of the holes give strength to the outer rails of the insert which in turn pushes against the side wall of your tyre for extra grip and stability.

Contoured Section

There are no proprietary valves needed, you can use any of the holes to loop over your valve and fit the insert around the rest of the wheel. No assembly is needed, we factory fit the components together so you have a secure well fitting product.

Fitting

27.5"
The Tyre Insert comes ready assembled. To start fitting, we suggest fixing the first bead of your tyre onto the rim, then position the insert so that any hole is placed over your valve and feed the rest of the insert onto the rim before putting on the second bead. Check the beads are seated and then inflate. This should take around 5 minutes.

Fitting

Will it Fit My Bike?

Rockstop rim protector is designed to fit MTB & EMTB with 27.5" and 29" wheels. If your rims are 24-34mm wide, a standard tyre insert will work for your bike. If you want to fit your EMTB wheels with a tyre insert and your rims are 34-44mm wide then a 29" WIDE rim protector is for you.

Reviews

We’ve personally tested them in big mountains, races and laps of the local woods and they’ve never let us down. That’s the sort of product we want to sell to our customers.

It survived a big hit from my local nemesis, and just carried on rolling.
