At Hope Technology, we’re renowned for making components that last for four years. Our test-winning brake, the Tech 4, was due for an update—not a reinvention, but a refinement.
Introducing the EVO: A step up in braking performance, with updates to both the master cylinder and calipers, EVO delivers improved control, power, and serviceability across cross-country, trail, and gravity disciplines. You’ll notice familiar names from our existing lineup—a deliberate move to make choosing the right brake easier than ever.
The Three Options:
EVO GR4 – 4 Piston Gravity Brake
Maximum power, zero compromise. Engineered for gravity and E bike use, the onepiece 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 designed not to be compatible with vented rotors, maximizing caliper stiffness and performance.
- One piece machined caliper for reduced weight and increased stiffness
- Four hybrid pistons allow smooth movement and excellent heat management
- The largest pistons for the greatest power
- The larger pistons increase the ratio of the brake by ≈ 6% when compared to the Tech 4 V4 brake system
- Improved caliper stiffness increases power and control
- Revised bore cap design reduces width for more frame clearance
- Choose this caliper for ultimate power in the most demanding applications
EVO TR4 – 4 Piston Trail Brake
Trail-proven power with balanced modulation. The one-piece TR4 caliper, featuring larger pistons and shared GR4 pads, delivers a 6.5% increase in braking ratio over the previous E4 system—ideal for trail and all-mountain use.
The ultimate trail-riding brake—impressive power balanced with a firm and consistent lever feel. Super-smooth lever actuation provides excellent braking feedback for absolute control.
- Four hybrid pistons allow smooth movement and excellent heat management
- Larger pistons for increased power
- The larger pistons increase the brake ratio by approximately ≈ 6.5% compared to the Tech 4 E4 brake system.
- Revised bore cap design reduces width for more frame clearance
- Larger pad improves lever feel and consistency
- Choose this caliper for power balanced with a firm lever feel and excellent braking control.
EVO X2 – 2 Piston XC Brake
Lightweight, smooth, and precise. The EVO X2 pairs the new EVO master cylinder with the X2 caliper for riders who prioritise lever feel and control over sheer power, making it ideal for cross-country and lighter-duty use.
The go-to brake for downcountry and XC use.
- One-piece machined caliper for reduced weight and increased stiffness
- Two lightweight phenolic pistons help maintain performance at high temperatures
- Post mount and flat mount versions
- Choose this caliper for light weight with excellent modulation and braking control
Engineered for the real world.
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, ensuring ultrasmooth operation throughout the full lever stroke.
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.
Key updates:
- 3 lever blade options: Standard, Control, and Power. (Control and Power are after-market purchases.
- Ergonomics: Redesigned lever with increased hook and new dimple texture for maximum grip and control in all conditions.
- Improved Modulation: New cam design and piston improvements deliver firmer bite point and improved feel throughout the braking zone.
- Smooth & Predictable Lever Feel: Upgraded internal piston mechanics and roller-bearing pivots ensure consistent performance and feel.
- Simplified Bleeding & Maintenance: A new master cylinder bleed port allows clean, tool-efficient bleeding without lid removal.
- Improved Pad Wear Consistency: Caliper tweaks to improve brake feel across the entire pad lifespan.
As with all our products, the EVO Brakes have been designed, tested, and manufactured in the UK. In keeping with the Tech 4 Brakes, they will be available in either black or silver, with coloured accents in the standard Hope colours.
