Hope Tech 4 Trial Zone Disc Brake Set

The all new Tech 4 Trial Zone 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.

Features

• 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
• Two huge 25mm aluminium pistons offer great power and stiffness
• Rigid CNC’d one piece caliper
• Designed to work with our Trial Zone rotors for optimum performance
• 30% pressure increase compared with the Tech 3 brake
• Hydraulic ratio improved by using a small diameter master cylinder bore
• Mechanical ratio increase for the best balance of increased power and modulation, resulting in usable lever feel
  throughout the full range of reach and bite point adjustment. The mechanical ratio has been fine-tuned using
  real
  riding data to provide its best efficiency at lever forces typically used during riding.
• Linear relationship between brake pressure and lever force making it easy and intuitive to control the braking
  power.
• Hinged clamp design to reduce weight and reservoir area increased to lower overall stack height. Shifter
  integration
  has been improved and now offers 30° of angle adjustment as well as neater packaging and compatibility with the
  latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range
  of
  lever position options.
• The Tech 4 retains the tool free bite point and reach adjustments from the Tech 3
• Only available with standard black hose
