GP1

Shore Hardness: ~55A (soft)

Pre-sanded and ready to use: Bring it to your resoling workshop, and they can take care of the rest.

Sheet Dimensions: Each sheet measures 15 cm wide × 70 cm long, providing ample material for multiple resoles or custom projects.

1. Feel & Performance: GP1 is the softest rubber in the RATOM line, designed to deform and “flow” into even the tiniest surface textures. That softness translates to unbeatable smearing performance and friction on low-angle or polished holds.

2. Best For: Cold or indoor conditions where rubber needs to stay pliable. Climbers who prefer sensitivity and a glove-like feel underfoot will love it.

3. Notes: Because of its softness, GP1 can wear faster under aggressive edging or outdoor granite, but its stickiness is unmatched when conditions demand maximum friction. We do not recommend using GP1 outdoors in extremely hot environments due to how soft the rubber becomes under heat.
