Is the insert available as a single - I only want it in my rear wheel?

Rimpact is sold in both pairs and singles, however we strongly suggest you buy a set for the following reasons:

At Rimpact, we believe that our inserts are best experienced as a pair. Rimpact's key benefit is in it's vibration damping qualities. Most of the vibration felt through the bike comes from the front wheel, through the fork and into your hands. This makes running Rimpact in the front wheel a necessity and will significantly improve the feel of your bike over rough terrain. The difference cannot be understated! It will also reduce fatigue over longer descents making running an insert in the front a must! 

We also believe in balance. We want Rimpact to only add positive attributes to your bike. If you run Rimpact in the rear only, your front tyre will feel vague and unsupported in comparison to the superior feeling you'll get from the rear. Weight isn't really a factor at as little as just ~95g's per 29" insert.

Another reason is support. The front wheel is the steering wheel and supporting the tyre to retain shape and grip is key to not washing out or under steering. By running an insert in the front you will be able to run a lower pressure to find grip but also be confident that the tyre will hold its line when you drive it through the turns.


Not enough reasons to buy a set rather than a single? How about being able to run lower pressures in the front tyre for extra grip where it is truly needed. If you have a set already but the rear needs replacing or you are upgrading to Mullet, you can buy a single on it's own through our shop.

What size do I need?

We've got a handy size guide page to help you answer that, all you need to know is your wheel size, tyre size and rim internal width measurement. Usually this is denoted by the name or sticker on the rim. 

If you still need help, head to our contact page and let us know as much info about the set up you are running and we will do our best to point you in the right direction.

Do you sell mullet / mixed wheel sizes?

Yes. We have many options in our shop and if you really can't find the fringe size you need, get in contact, we can do custom sets in our Original, Pro, Gravel/Xc, and in some cases EDH and CX models.

Do you ship internationally / How do I get Rimpact in my country?

We ship to almost all countries! There are a few we can't ship to economically so if the shipping cost at checkout don't look right, get in touch and we can do you a custom quote. Delivery times vary country to country but on the rough breakdown is:

1-2 days UK

2-5 days European Continent

7-14 days - US

~14 days Canada and rest of world.

In some countries we have dealers situated to ship our products direct from the same country to save on extra taxes and time. 

We ship outside of the UK via tracked and signed  services for a super reasonable rate. Please note some countries cannot support a tracked service, such as Mexico, Chile and Argentina. For more info head to our Shipping page.

How much is shipping?

Shipping rates vary depending on country, product and quantity. By adding items to your basket and updating the shipping details you'll get an accurate breakdown of charges. 

We partially subsidise shipping internationally to ensure all our customers can get a set of inserts in their bike at a reasonable cost. We DO NOT make any profit on International shipping fees, in fact loose a fair chunk of the gross profit. Rimpact is happy to provide weights and measurements for fact checking purposes if you wish. We can also accommodate using your own shipping company if you have one and wish to use it. Please get in touch for more information on how to do this.

More info on shipping to your country on our Shipping page.

Why should I buy Rimpact, I never get punctures?

Makes lower pressures more viable.
Supports the tyre sidewall to reduce tyre roll.
Reduces burping by stabilising the tyre bead.
Significantly reduces vibration, trail chatter and trail feedback.
Increases the confidence you'll feel in the bike at higher speeds and over gnarlier terrain.
In terms of weight it is light enough to be practically or totally unnoticeable when pedalling.
Will get you out of a tight spot by acting as a run flat if you forget your tube when you inevitably do get a puncture or tear your tyre on something sharp miles from civilisation.

What tubeless sealant works with Rimpact?

Any on the market today. Rimpact Foam is inert and will not react with Latex, Ammonia or any of the other agents in the current range of sealants on the market as of January 2022 - that we know of.


That said we recommend Stans Sealant. We have worked extensively with Stans and many other sealants during testing and development and have found the OG to be the best option. As such we began stocking it in the shop so that our customers could have a one stop shop for new tubeless set ups. 

How long does Rimpact last before wearing out?

How long is a piece of string? We have heard from customers who have had theirs fitted for 4+ years and still going strong. Others wear theirs out in much less time.


Rimpact ORIGINAL will last, on average, 6-12 months, or more in a normal use case. 

Rimpact PRO is more burly by nature and as such will last longer on average thanks to its tougher layer. However both versions of the insert are designed to sacrifice themselves in favor of saving your rims and tyres. As a result, super low pressures, thin or worn tyres, riding on flat tyres can accelerate wear. The insert usually out lasts a tyre and the life can vary from user to user. For Ebike use, we'd recommend a PRO insert over an ORIGINAL as it's more heavy duty nature is much better at handling the heavier weight of Ebikes and the torque output from the motor.  

If I buy more than one set can I get a discount?

This used to be the case. However we've made significant improvement and efficiency changes to the products, packaging and couriers we use in order to squeeze every last penny and allow our customers to purchase the best insert on the market at one of the lowest prices. As such we can no longer offer a multi buy discount for only 2-5 sets.

If you have a requirement for 5+ sets we may be able to offer a better price on a case by case basis so get in touch!

Do my tyres need to be tubeless before installing Rimpact?

Yes. Rimpact only works with tubeless set ups. They cannot be used with tubes. If you don't have your tyres set up tubeless yet, you can purchase the gear you'll need from our shop at the same time as buying the Insert. You'll need:

  • Tubeless rim tape - to prevent air escaping through your spoke holes.

  • A tubeless compatible tyre - most are rated for tubeless nowadays (usually has 'TR' or 'Tubeless Ready' written on the sidewall).

  • Tubeless Valves - You'll need Rimpact Tubeless valves or another insert compatible valve to use a Rimpact Insert so make sure you pick them up when buying your inserts rather than purchasing expensive valves you won't need.

Do you have a distributor in my country/Can I buy for my shop? 

At present Rimpact is primarily a direct sale business, however we do have a B2B set up on this website where stores world wide can purchase Inserts for resale. Head to the menu at the top of the page and select B2B for more information. We have a small number of Distributors in certain regions world wide and are always looking to expand. 

What happens if I can't fit the inserts - can I have a refund?

99% of the time Rimpact is straightforward to fit for competent tyre fitters, however there are certain rim/tyre combos even the most proficient tyre fitters struggle to install. If you are struggling to get your inserts fitted, reach out to us and let us know the particular point you are stuck at, and we can troubleshoot from there.

In some cases, we may suggest taking your wheels to a workshop/professional that has experience in tubeless setup, as they should be able to assist you: as skilled as you might be, nothing quite beats the knowledge and expertise of someone who fits tyres day in and day out.  We offer a refund on a case by case basis, providing all the necessary steps to fit them have been taken, and the inserts/packaging are in suitable condition for resell.
