EVO GR4 Brakes Standard Hose
Maximum power, zero compromise. Engineered for gravity and E bike use, the one-piece GR4 caliper features a stiffer one-piece body, larger pistons (6% more power vs Tech 4 V4), and a slimmer profile for better frame compatibility. They are deliberately not compatible for vented rotors, to maximize caliper stiffness and performance.
EVO Master Cylinder: The Master cylinder features a new cam mechanism to reduce free stroke while maintaining the feel and modulation, a key feature of the much-loved Tech 4. The piston assembly—features a secondary guide bush and sliding guide—ensures ultra-smooth operation throughout the full lever stroke.
EVO GR4 Calipers: The caliper bodies have been refined for greater stiffness, improved hub/frame compatibility, and streamlined profiles. Bore cap designs are optimized to reduce width and improve fit across modern frame geometries. GR4 calipers are for gravity riders who need maximum power with no compromise. Super-smooth lever action and premium construction make controlling that power feel natural. The benchmark brake for gravity and e-bike use.

Key Updates
-
Optional Control and Power Lever Blades, shaped for riders who prefer their brakes to bite at the extremes of the lever adjustments.
- Control: For riders who run their bite point close to the bars.
- Power: Bite point further out.
- Redesigned lever with more pronounced hook and dimples for more confidence in wet or cold conditions.
- New cam design and piston provide a firmer bite point and more feel.
- Upgrades to the lever bearing and piston add to the T4's already incredible feel and consistency.
- Clean, simplified bleeding thanks to a new bleed port in the master cylinder.
- Caliper tweaks enhance the consistency of performance as the pads wear.
- Largest pistons in the EVO range for the most power - around 6% more than the V4.
- Improved caliper stiffness.
- Lower profile shape with new bore cap design for more clearance.
