Tektro R539 Road Caliper Set Front & Rear Silver 47-57mm QR

Shimano BR-R451 Road Brake Calipers

• Compatible with STI and brake levers that are Super SLR enabled (e.g. Dura Ace Di2 7970, Dura Ace 7900, Ultegra Di2 6770, Ultegra 6700, 105 5700, Tiagra 4600)
• Light action and accurate brake power
• Adjustable toe-in brake shoes
• Use of these calipers with standard SLR enabled STI and brake levers results in a "mushy" brake response

The eeBrake G4 is the fourth generation of the legendary eeBrake featuring 100% CNC machined parts, a wider design optimized for 22 – 28mm rims, stiffer black arch spring, a revised one-piece center adjuster with built in resistance for easier use and ghosted laser etching that will stand the test of time – all with the same extraordinary stopping power and light weight that you’ve come to rely on from eeBrakes.

• The eeBrake titanium cable adjuster pivots as the brake is applied, optimizing cable alignment during brake actuation
• The cross cable path aligns the brake cable over the center of the brake which provides a clean and aerodynamic line, moving the cables into the “wind shadow” of the frame
• Cable housing extends to lower tip of the cable adjustment screw eliminating added friction to provide even and friction-free braking power
• Tool-free caliper centering adjustability provides super-precision and pad motion consistency
• One simple flip of the lever on the Quick Strut release opens wide enough to easily clear a 31mm tire, allowing for easy wheel removal
• Optimized to work with Shimano, Campagnolo, and SRAM levers
• Hand-built in Fletcher, NC
