TRP DH-R EVO 4-piston hydraulic disc brakes, front and rear, with rotors

A complete 4-piston hydraulic disc brake upgrade for mountain biking: two pre-bled TRP DH-R EVO assembled sets (lever, hose and caliper DH-R EVO with pads fitted) plus a pair of TRP 2.3 mm rotors. Each side arrives assembled, filled and bled, so it bolts on without a bleed when the hose lengths suit your bike.

Kit includes

• Front: DH-R EVO 4-piston post-mount caliper with its lever, pre-bled (fitted on the right in Australia)
• Rear: DH-R EVO caliper with its lever, pre-bled (fitted on the left in Australia)
• 2 x TRP 2.3 mm 6-bolt rotors, 203 mm

Options

Rotor sizes: 6-bolt: TRP 2.3 mm 180, 203, 220 mm. The kit defaults to two 203 mm (TRP 2.3 mm); set that row to 0 and pick another size, or mix sizes (a larger rotor at the front is common). DH-R EVO takes 180 to 223 mm rotors (TRP figures).

Fit-up parts, sold separately (linked here and shown with this kit): TRP mineral oil, a bleed kit. Add what your bike needs to the cart alongside the kit.

This kit is the 6-bolt version - ask us for Centre Lock rotors if your hubs need them.

Already have rotors? Untick them and the price follows the parts you keep. Every part in this kit can be deselected, so a bike that only needs one end, or already has the right rotors, is not charged for the rest.

Fitting notes

Australian convention: the right-hand lever works the front brake and the left-hand lever the rear; the sets are built that way. Most post-mount forks and frames take a 160 mm rotor directly; check your fork or frame's native size - a larger rotor needs the matching TRP adapter only when the mount is smaller than the rotor (not part of this kit - reuse the bracket already on your bike, or ask us). 6-bolt rotors bolt straight to a 6-bolt hub. Service fluid: TRP mineral oil.

Tune Cycles supplies and fits these brakes. Choose your options above; if you are unsure what your fork, frame or hubs take, ask us before you order.
