TRP R970SL brake callipers



Lightweight brakes that pack a punch – but you'll have to dig deep to pay for them

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Mmmm! And again… Mmmm! What we’ve got here, ladies and gentlemen, are the brand spanking new dual pivot offerings from TRP. They’re made from forged magnesium that’s then machined, along with titanium hardware and SwissStop Flash cartridge pads. And they hit the scales at – wait for it – 215g the pair, including fixings. For the weight-obsessed out there, that’s getting on for 80g lighter than Shimano’s top-end Dura-Ace callipers.

Unlike some lightweight brakes that sacrifice power for grams, the good news is that these actually work properly. In terms of feel, you’d be hard pressed to tell the difference between these and Dura-Ace. They’re compatible with the different pull ratios of all the major lever brands so you can bang them straight on your bike without any worries.

There’s no quick release lever; instead, you push the brake shoes together, lift the barrel adjuster out of its housing and move it inward on the slotted brake arm. It works fine and saves a little weight.

Aside from that, the cable adjustment bolt is easy to operate on the fly, you get a centring and toe-in adjustment, and they look super cool. Love ’em.
