Absorbent by JRS Racing
Greater comfort, grip and control for your mountain bike suspension
A new approach to MTB suspension
Absorbent is a major innovation in the world of mountain bike suspension. Absorbent replaces rigid tokens with variable-density elastomeric foam.
Thanks to its air-permeable cells, the suspension becomes more progressive and significantly more comfortable.
- Compatible with leading suspension brands (RockShox, Fox, etc.)
- Adjustable on the track using JRS to suit your riding style
- 30% better performance, without changing your current suspension
- Price: between €120 and €160, depending on the model

How does it work?
Absorbent replaces the rigid spacers usually found in suspension systems.
Instead, a smart foam is fitted which allows air to pass through its cells. The result is that the suspension responds more gradually and absorbs shocks more effectively.
Installation is simple: the system is screwed or clipped onto the inner tube valve cap. The foam remains suspended, without ever touching the piston, which prevents any unnecessary friction. The plastic bracket, meanwhile, was designed in the laboratory to improve airflow during compression. It is the central component of the ABSORBENT system.
Damping effect: the suspension remains sensitive and responsive
Quick, controlled rebound for better absorption of successive impacts
Adjustable resistance depending on the foam pads selected
Compatible with existing systems — no need to change everything
How it works
Who is Absorbent meant for?
Don’t be mistaken: Absorbent isn’t just for competitors. It’s designed for all riders looking for comfort and enjoyment.
Whether you ride an e-bike or practise another discipline, whether you’re an amateur or one of the world’s top competitors — that’s the real strength of Absorbent.
A well-tuned suspension means less fatigue, fewer punctures… and a lower risk of falling.
So, are you ready to give it a go?
Use and maintenance
Installation is quick and easy:
- A plastic part is attached to the fork cap
- The foam cylinders, selected according to the desired level of progression, are then inserted and held in place by a plastic clip at the end
Maintenance
- It is recommended that the foam pads be replaced once a year
- Over time, the air pockets and repeated deformation of the foam can affect performance
Durability: Our foam pads are designed to last, but replacing them regularly ensures they continue to perform at their best
How it works
The History of Absorbent
Our goal
To create a high-performance system that is easy to install and accessible to everyone.
Development
Absorbent was developed over several years, with extensive testing carried out on all types of terrain.
Observation
An idea born out of a real need on the ground: greater sensitivity, without making the suspension any more complicated.
Result
An innovative system that makes a difference from the very first time you use it.
