Bump Rubber STANDARD 13 ID & 16 ID x 32 OD x 15 H (mm)

Bump Rubbers meet the highest standards for repeatability and durability, indeed one of our prototypes successfully completed the LeMans 24hrs with minimal fretting or wear despite being compressed to its limit numerous times per lap..
KINETIC R COMPOUND

The Ultra Low Hysteresis ‘R’ compound is available in
50, 60, 70 and 80 Shore Hardness as standard.

R compound is the lowest hysteresis bump rubber currently available. During ‘on track’ and 7 post rig testing it has shown to significantly reduce tyre contact patch load fluctuation associated with higher hysteresis bump rubber compounds.

It also offers extremely low cycling sensitivity and stiffness reduction per degree of temperature change.
Reduced tyre contact patch load variation.
