Formula The One disc brake review£288.90

Fantastic fingertip control

BikeRadar score3.5/5

Formula have a new flagship mountain brake, the RO, but its predecessor still offers amazing power and control-to-weight ratio for those who can afford it and are prepared to look after it.

The R1 cross-country brake master cylinder helps The One come in under 400g, even with an oversized calliper, so it’s ideal for trail or enduro downhill use. The big pistons and pads give huge amounts of power. Rein it in though, and the softly-squeezed modulation gives fantastic fingertip control in the sketchiest traction conditions.

Bedding in with the sintered pads is quick and they last well in wet conditions, but the small bolts and internals need more TLC than most. Formula rotors and mounts are very expensive, but with modular selling, you can buy the brake alone for £229 and use your old hardware.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
