Scroll to witness the transformation
01: The Origin
Rubber pushed to its absolute limit on circuits that demand perfection. This is where our compound begins its life.
02: The Rebirth
What others discard, we transform. Hand-processed in Japan: the same rubber, reborn with purpose.
Three compounds. All born from the same Grand Prix racing slick: reclaimed, hand-processed, and ready to perform on rock, wall, and everything in between.
The softest rubber in the GP line. Flows into surface texture with a high sensitivity: offers unmatched smearing and friction performance.
The same racing-slick DNA as GP1 Soft, with added firmness. High grip meets improved rigidity and stiffness: the most versatile compound in the lineup for climbers who want everything.
Built for all-round climbing without compromise. Firm enough for edging, grippy enough for everything else. The workhorse of the GP line.
We supply professional resole workshops across Europe with GP Rubber sheets. Join our growing network of partners.
The conventional way
Natural and synthetic rubber sourced globally, including natural latex from Southeast Asia and petrochemical-based polymers.
Raw materials transported internationally to industrial compounding facilities before processing.
Energy-intensive sulphur-based vulcanisation using heat, pressure, and chemical accelerators to create new rubber compounds.
Finished rubber sheets distributed through multi-stage global supply chains before reaching workshops.
The RATOM way
Grand Prix racing slicks reach the end of their race life. The compound has already been pushed to its absolute limit, and perfected under conditions most materials never survive.
Collected instead of discarded, these slicks are sent to our workshop in Japan. No new raw materials. No virgin rubber required.
Hand-processed by craftsmen in Japan. The compound is already exceptional. We don't reinvent it. We reclaim it.
GP Rubber sheets distributed across Europe, to resole workshops. The same rubber that survived the circuit, now under your feet on the rock.
Given a second life.
Built to send.
Handcrafted in Japan
Every sheet of GP Rubber is hand-processed in Japan by craftsmen who treat material like an art form. This isn't mass production: it's the kind of care and precision that the Japanese have applied to their craft for generations. The result is a rubber sheet with consistency, character, and performance that no automated factory line can replicate.
