In this testing sequence lasting 600s (10 min) and using a one-of-a-kind machine, we performed a simulation of a long descent on a road bike, with a constant force of 10N on the brake lever and slope angle of 12,5%. SRAM AXS pads fit any of their current 2-piston road calipers for RED, Force, Rival, etc.). All pads will fit any caliper with a compatible pad size and shape ( i.e. The 34/35 models use a performance road compound, while the others use an endurance mountain bike compound. GRAPHENpads for Shimano XTR mountain bike brakes. The absoluteBLACK GRAPHENpads brake pads will be offered in five versions, all prices are per wheel: These and the XTR pads below use straight cuts, not angled, so they look thin when viewed straight on. GRAPHENpad models & pricing GRAPHENpads for SRAM G2 mountain bike brakes. The shapes and designs of the fins vary by model and come on all versions except for Shimano Deore brakes.Īs they explain further down, air flow is key to temperature regulation, but they say graphene’s extremely high thermal conductivity is what pulls so much more heat away from the pads and up to the fins for quicker, more complete cooling. The graphene-coated steel backing plates use a patented angled cut on the finned radiators to pull heat up and away from the pads and calipers. absoluteBLACK GRAPHENpads disc brake pads for SRAM AXS road and gravel brake calipers. It’s also quiet.ĪbsoluteBLACK developed and is manufacturing their pads and compounds in Europe, drawing on automotive tech that’s already seeing graphene used as a higher-performance copper alternative.

And, it’s free of copper, which they note becomes dust during braking, and that dust is toxic to marine life and will be banned in California starting in 2025. The pad compound uses a “specially modified graphene” which offers good friction and durability while also transferring heat to the backing plates more efficiently. The angle of the cuts produces the illusion that they’re very thin when viewed from the right angle. GRAPHENpads for Shimano Dura-Ace brake calipers. Their research showed that heat buildup was the number one reason for reduced braking performance, so the combination of materials and design promise to keep initial bite and power modulation consistent even in heavy use. The new absoluteBLACK GRAPHENpads disc brake pads use an all-new combination of graphene-coated-and-finned back plates and graphene-infused pad compounds to reduce heat and prevent brake fade.Īfter three years of development and testing, they say these new brake pads offer up to 35% better braking performance by keeping them much cooler during prolonged descents.
