RX4+ Caliper

The RX4+ caliper supersedes the RX4 caliper and builds on 25 years’ experience designing and manufacturing hydraulic disc brakes and transfers the knowledge and skills acquired into the world of Road and Cyclocross dropbar brakes. A precision CNC machined monobloc design results in a stiffer caliper to give unrivalled feel and modulation.

We are keeping with the current model of offering a Postmount caliper, Flat Mount Front Direct and Flat Mount Rear Direct calipers with the addition of a new Flat Mount caliper.
The following calipers will now be available. 

• RX4+ Postmount Not changing

• RX4+ Rear Flat Mount Direct FM +20mm  
• RX4+ Flat Mount: FM NEW!
