While Shimano introduced the flat mount standard for road bike disc brakes, it’s inevitable that SRAM would have to offer something once frame and fork manufacturers adopted it. And now they have, offering flat-mount options for all three of their hydraulic disc brake road groups.
Available for both 140mm and 160mm rotors thanks to a flip flop adapter, you’ll be able to pick from RED, Force or Rival setups come September. The front brake calipers are shown above, the rears, plus specs, weights and pricing, are below…
The calipers are the same front and rear, it’s just the adapters shown here that make the rears look like they sit lower. They’re shown here with the adapters in position for a 160mm rotor, which is SRAM’s recommended rotor size for road applications. Flip them around so the taller part is at the top and they’d be positioned for 140mm rotors.
Claimed weights are Rival 496g for Rival, 489g for Force and 459g for RED, the key differences being materials just like on the originals – bolt material goes from stainless to titanium for RED, but there are also brake lever material differences between the models that also contribute to the differences. All weights are for the front brake with 160mm rotor, 800mm hose, mounting bracket and hardware. Performance, bleed procedure and other technical details are the same as the standard mount versions.
Retail prices (VAT included for € and £) per wheel for the shift/brake lever and flat mount caliper are:
- SRAM RED 22 HRD: $493/ €514/ £394
- SRAM Force 22 HRD: $375/ €391/ £300
- SRAM Force 1 HRD: $315/ €329/ £252
- SRAM Rival 22 HRD: $355/ €370/ £284
- SRAM Rival 1 HRD: $284/ €296/ £227
All three will have aftermarket retail availability in September 2015.
