Quad QHD-1 Sting review£90.00

An excellent sub-£100 disc brake option

BikeRadar score4/5

The Sting is an excellent sub-£100 option and bodes well for Quad's upcoming Axis and Dime brakes.

It’s not the pimpiest brake, looking extremely similar to Diatech’s cheaper Anchor, just without the plastic logo panels. However, like the Diatech it’s proving very reliable, and the chunky lever is well shaped to flatter the decent levels of modulation and power. Dyno results last year proved it actually handled heat better than any other brake we tried too, so its Alpine brake credentials are excellent.

Split lever clamp and slotted Hayes style makes it very easy to fit, and new compound pads seem to be lasting better than ever. A different rotor also makes it noticeably lighter than the £20 cheaper Diatech, although performance is otherwise very similar.

The ‘Pro’ gets bite point adjustment, braided metal hose and wavey pulse rotor upgrades for only £20 more. Basically, here you get highly dependable and controlled brake for under £100.

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.
