Which bike is the Session Rim Protector made for?

The Session rim protector can be used on Mountain Bike XC, XCM, Enduro or Downhill, E-bike or Gravel bikes, it does not matter, it will guarantee all the above safety of your rim and your tire. We'll explain later!

In addition, the rim protector allows you to ride with less air in the tire, that is, with less pressure. Only with a good rim protector you can guarantee that your tire does not leave the rim.

And why use a tire with less air?

Combined with the tubeless system and modern tires with a flexible side, the lower pressure will directly increase the grip of your tires when cornering, as well as greatly improve the traction on technical climbs avoiding those skidding that make you put your feet on the ground.


More tire in contact with the ground

The increase in grip and traction happens because with less air in the tire calibration of your bicycle you can significantly increase the area of ​​contact of the tires with the ground.

In mountain biking and Gravel, in general it has already been proven that an empty tire does not directly mean more drag. In fact, this can be beneficial, returning as less loss of power due to excessive shaking of some.

Literally, your tire bounces less and does not lose torque and traction, it is as if it absorbed small stones, branches and slight ground unevenness. And that makes it jump less and stay more on the ground, transmitting all the force of the pedal to push it faster forward.

In addition, this improvement in tire performance brings not only speed, but also safety and control on technical descents thanks to the increased braking power.

Now it’s easier to understand why I should use a rim protector

Now it's finally clearer and easier to understand what a rim protector is for and how your bike can be used. In addition to avoiding the famous snake bite (punctures on tire's side wall) that cuts the tires and crumples the rim - sometimes even condemning its rim sheet , it still provides you with more performance and more safety.


Who should use a rim guard?

Everyone who rides on trails, roads with many rocks, branches and urban obstacles, such as curbs and very rugged tracks.


Unlike what you can imagine, the rim protector is also recommended for beginners, especially on mountain biking. It is common for newbies to not yet know how to pass some obstacles.

This extra protection ensures that a beginner without much experience in overcoming obstacles will cut the tire or bend the wheel. But it can also help the beginner to gain confidence in turns and descents.

Athletes and Advanced Skills

For the same reasons as the beginners, but now the rim protector enters providing more security in maneuvers and ensuring that the athlete does not need to abandon a race due to a cut in the tire.

In addition, the extra seconds gained with faster turns, which consequently require less energy to resume speed, and even greater control of the bike are increments that every athlete seeks. With the Session rim protector you can achieved this.

Do only carbon rims need the Session Rim Protector?


Session Carbon Wheel C26 (coming soon)

This is a big myth, as both the carbon wheels and the aluminum wheels get the same benefits with the rim protection system.

However, there is a belief that the aluminum wheel does not need a rim protector, which is wrong, since aluminum is more easily bent than carbon.

The Session rim and tire protector will cushion impacts on the rims of your bike, ensuring integrity and avoiding dents and cuts in the tire. Whether your wheel is aluminum or carbon, it doesn't matter.

Is the Session rim protector compatible with my tire and wheel?

The Session rim protector works well on any rim or tire width,it is compatible with wheel sizes 27.5 ″ or 29 ″.

The Session protector is produced in five different sizes: X-Small, Small, Medium, Large and Extra Large (+sizes). Check the Size guide below to ensure that the product works well on your bike:

Available sizes: 

    • Extra Small / Gravel : 17 to 23 mm
    • Small: Rims from 21 to 26 mm, with tires 2.1 ″ to 2.4 ″;
    • Medium: Rims 25 to 35 mm, with tires 2.25 ″ to 2.5 ″;
    • Large: Rims from 34 to 45 mm, with tires 2.5 ″ to 2.8 ″;
    • Gravel: Rims size 650 or 700 up to 42mm tires.
    • Extra Large : 38 to 50 mm 

Although it does not absorb liquid, the sealant is highly adherent. This way, a small part of the liquid will settle throughout the product. Therefore, when installing it, it is necessary to add 3 to 5% more sealing liquid.

Is the installation of the Session rim protector complicated?

It is very easy to install your rim protector, there is no need to remove the sealant you were already using and it also helps in sealing tires with the first tubeless installation.

Just adjust the size of the rim protector on the wheel of your bicycle. If you need to cut it, no problem! This can be done easily with any common household scissors.

Then, we suggest adding a little more sealant, somewhere between 3 or 5% more. As we said, the new system does not absorb the liquid, however due to the sealant's own characteristics it may end up sticking a little to the protector.
