Brembo GR-PRO Brakes: Three Adjustments, One Big Tradeoff
Brembo's GR-PRO brakes offer three independent adjustments and World Cup pedigree. Here's what €1,200 buys you—and who should care.
Brembo just opened pre-orders for their GR-PRO mountain bike brakes—the same red calipers Specialized Factory Racing ran to three World Cup wins last year. They're not cheap (€900 for the kit, rotors sold separately), and they only come in one color. But the adjustability here is legitimately different.
Most brakes give you reach adjustment and maybe a bite-point dial. The GR-PRO has three independent levers: reach (40 clicks), dead stroke (7 positions), and a ratio adjustment that changes the mechanical advantage between your lever pull and the master cylinder. That last one—S/M/H settings—alters how the brake fundamentally behaves. Soft gives you a long stroke with lower force. Hard gives you a short stroke with higher force. It's a non-concentric socket on the lever ball, so rotating it physically repositions the pivot point.
Here's the catch: this level of tunability assumes you want to tinker. If you just want to bolt brakes on and ride, you're paying for features you won't use. The tester who rode these back-to-back in Italy ended up fastest in medium-front/soft-rear—a combo he wouldn't have guessed without multiple laps. That's the promise: dial in power and modulation independently, maybe even swap settings between dry hardpack and wet loam. But it also means you need the time (and the trail access) to iterate.
The hardware is solid. Four 18mm pistons, insulated to manage heat. Braided stainless lines with a PTFE core to limit expansion under load. 2.3mm rotors in 200 or 220mm, one-piece construction with a trailing-spoke pattern borrowed from MotoGP. One semi-metallic pad compound for now—high initial bite, claimed thermal stability. Mineral oil instead of DOT, formulated in-house for low viscosity across temperature swings.
Pricing is the other constraint. €900 gets you the brake kit (two levers, two calipers, hoses, bleed kit, and a spare set of pads). Add €144 for rotors, another €21–30 for caliper mounts or shifter adapters. You're looking at €1,100–1,200 all-in. That's more than SRAM Code RSC or Shimano Saint territory, and those have years of field data. Brembo's pedigree is motorsports, not mountain bikes—I can't verify how these hold up after a season of wet grit and frame flex. Europe-only launch in July, broader markets later if demand supports it.
