ZRACE BR-005 Cable Actuated Hydraulic Disc Brake Enlarge the Piston For Road Cyclo-cross CX Bike, CycloCross
Disc-Brakes
The reviewer discusses the ZRACE BR-005 Cable Actuated Hydraulic Disc Brake as part of their bike build. They mention that these brakes are cable-actuated hydraulic disc calipers, meaning they are controlled by a cable but have a small oil reservoir inside that triggers the pistons. The reviewer notes that this wouldn't be their first choice of brake setup now, but at the time of building the bike, fully hydraulic drop shifters and brakes weren't available on a budget. They highlight that the brakes have performed well overall, with no issues during emergency stops, though they acknowledge that fully hydraulic brakes would still be better.
AI Summary
Pros
- Performed well overall
- No issues during emergency stops
- Affordable option at the time of purchase
Cons
