Overview
Hope EVO GR4: four-piston gravity and e-bike brake with the EVO lever and a stiffer one-piece caliper with larger pistons, £240 UK RRP per end.
The EVO GR4 is Hope's four-piston gravity brake for the most demanding applications, described by Hope as the benchmark brake for gravity and e-bike use. It delivers maximum power, and a super-smooth lever action and premium construction make that power feel natural to control.
The EVO lever adds an increased lever hook, a dimpled blade, a new cam that shortens free stroke while keeping modulation, a roller bearing main pivot, two guide bushes and a bleed port on the master cylinder body. The one-piece caliper uses larger pistons for more power and a slimmer bore cap design for better frame compatibility.
