These are Hope replacement disc brake pads in the HBSP323 shape, which fits Hope E4 calipers along with RX4+, RX4-SH, and Mono M4.

What it's for

Brake pads are a wear item. Replace them when the pad material is nearly gone or when they have been contaminated with oil. These are Hope's own pads for its four piston E4 caliper.

Compatibility

• Fits: Hope E4, RX4+, RX4-SH, and Mono M4 calipers
• Other Hope calipers: use different pad shapes. Check Hope's brake pad guide for your model.
• How to check yours: The caliper model is marked on the caliper body. You can also compare the backing plate shape of your old pads.

How it works

Hope's compounds: Hope color codes its pads. Green is Racing, a resin compound made for more power, a short bed in time, and fade resistance. Red is All Conditions, made to hold up in very wet and muddy terrain. Gold is Sintered, a full metallic compound with fade resistance at high temperature and consistent feel in all weather. Purple is E-Bike, made for the extra weight and speed of electric bikes. Blue is Road.

• Service: OMG's bike shop can fit pads and check your rotors.
