The Hope Tech 4 EVO TR4 embodies the ultimate evolution of trail braking for demanding riders. With its stainless steel braided hose and Black/Silver finish, this 4-piston hydraulic brake for left hand (front position) delivers 6.5% greater braking power compared to the previous Tech 4 E4 model, while maintaining a firm, progressive and perfectly controlled feel on the most technical terrain.

Technical architecture and EVO innovations

The CNC-machined monoblock caliper in 2014 T6 aluminum guarantees optimal rigidity and exceptional power-to-weight ratio. The 16 and 17 mm hybrid pistons ensure remarkable thermal management and even pad wear (shared with the GR4 model). The new EVO master cylinder incorporates a floating cam system that reduces lever dead stroke while preserving feel and modulation in the braking zone. An integrated bleed port facilitates maintenance without removing the cover, while the piston benefits from a secondary guide bushing and ball bearing pivot for ultra-smooth action.

Technical highlights

• Trail power and control: designed for medium-duty use (trail, all-mountain, enduro), the TR4 delivers impressive power without excessive aggression, with fine modulation for absolute control.
• Ergonomic EVO lever: extended lever blade for greater security during aggressive riding, dimpled surface for firm grip in all conditions, and tool-free reach and bite point adjustments.
• Premium braided hose: superior resistance to expansion, consistent hydraulic pressure and increased durability compared to plastic hoses.
• Lightweight monoblock design: redesigned caliper with optimized cylinder plugs for improved frame clearance and reduced bulk (6% slimmer than V4).
• Complete British manufacturing: entirely designed, tested and manufactured in Barnoldswick (England) — guarantee of quality, traceability and world-renowned expertise.

Configuration and available variants

This model corresponds to the left hand version (L/H), typically mounted on the front. The supplied braided hose measures 1700 mm and can be cut to the desired length (olives and inserts included). The brake is delivered pre-bled with DOT 5.1 fluid, ready to install with Post Mount 74mm mounting. The EVO system is compatible with three interchangeable lever profiles (Standard, Power, Control) sold separately to customize feel according to your riding style.

Available variants

• Left hand (L/H - front): EAN 5056850913224 — Black/Silver finish, braided hose
• Right hand (R/H - rear): available in the same configuration (braided hose, various color combinations Black/Silver, Black/Purple, Black/Smoke, etc.)
• Color options: black or silver body, with colored accents (Silver, Black, Smoke, Blue, Red, Purple, Orange) to customize aesthetics
• Plastic hose version: referenced separately, with upgrade possible via HT-1050 kit (stainless steel braided hose)

Proven performance and reliability

With a measured weight of approximately 285 g (front brake with cut hose and accessories), the TR4 ranks among the best trail brakes on the market, rivaling references like SRAM Code Ultimate or Motive. The system uses shape 40 pads (compatible with Hope E4, RX4+, RX4-SH, Mono M4) available in organic or sintered compound. The manufacturer's 2-year warranty and Hope's commitment to supply spare parts for a minimum of 10 years after end of production demonstrate the durability and serviceability of this iconic product of British craftsmanship.
