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.
KEY FEATURES
- Dot Fluid Calipers will have Bore Caps with a D etched.
- Mineral Oil Caliper will have Bore Caps with an M etched.
- Calipers to suit dropbar set ups - Flat Mount front & rear & Post Mount
- Calipers designed to fit 140, 160 & 180mm rotors
- Slimline 4 piston lightweight design
- Monobloc design creates a stiffer caliper reducing the fuzzy lever feel and brake pad rub
- Available in Black, Silver, Bronze, Red, Blue, Purple and Orange
- Top entry pad fitting
- CNC machined from 2014 T6 aluminium

The Tech 4 E4 builds on our 25+ years’ experience designing and manufacturing hydraulic brake systems. The Tech 4 uses all new internal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reduced. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and keeping our legendary feel and modulation.
The updated E4 caliper utilises hybrid style Stainless steel pistons with a phenolic insert allowing for smoother movement and less maintenance, while still able to manage high temperatures without heat transfer during extreme use. Increased power versus Tech 3. Lever shape updated to provide a more ergonomic shape orientated to provide the best mechanical advantage during braking. Hinged clamp reducing weight and ergonomics. Shifter integration improved for more adjustability. Tool free bite point and reach adjustments. Rigid CNC machining.

The Dura Type insert pad was originally developed as an aftermarket upgrade for high end Shimano brake systems. The Kool-Stop Dura pads are the same spec as Shimano pads and fit Shimano, SRAM, TRP and Tektro holders with a set screw.
Compounds:
- Black: Kool-Stop's standard compound which is great for all weather conditions, but designed for dry condition riding.
- Ceramic: This compound was designed for ceramic coated rims and is great in all weather conditions.
- Salmon: Kool-Stop's most famous Salmon compound is also one of the most aggressive compounds for extreme all weather conditions especially in the wet, but still superb in the dry.
- Carbon: Kool-Stop's original carbon compound which works great for most carbon wheels but will wear quicker on fast steep descents.
- Dual: A fusion of Kool-Stop's two finest compounds which will give superb braking in all weather conditions. This combination produces a more controlled smooth stop!
