Onza has a new, super sticky rubber compound developed by Visco Lab in Switzerland.
It’s starting with the new GRP 40 DH compound made to performance in the gravity disciplines, which includes enduro these days. The compound has a slower rebound, which makes for a more consistent feel and better traction since the rubber stays in contact just a little bit better. It’s a bit softer than the 45 and 55 Shore-A rubber used in their other casings, equivalent to about a 40a.

The video compares a higher durometer (first clip) to the new GRP 40 DH compound, which bounces substantially less. In person and with multiple drops of each, it was very evident.
It’s used as a single compound because it makes for more precise manufacturing process so the quality of each tire is better and more consistent than if they were trying to blend compounds.
It’ll come on the Ibex, Citius and Greina tread patterns, all 2.4″ wide for 27.5″ and 26″ tires.
Pricing will be the same as their standard compound tires, around $90-$105 depending on model. All of those have their DH casing when you opt for the GRP 40 rubber. Available in mid-May. Eventually the new rubber compounding will make its way to trail and XC, too.
