Sinter Model 020 Hope

Hope's Tech V4 caliper is the newest four-piston design in the British brand's catalog, with a refreshed pad pocket and a larger piston area than the Tech 3 generation it sits above. The Sinter Model 020 is the organic-compound pad specifically built for the Tech V4. One pad shape; one caliper family.

What's in the kit

One caliper's worth of pads (2 pads, left and right) for the Hope Tech V4 pocket. The kit ships with the spring, pin, and bedding-in instructions. Order two kits if you're replacing front and rear pads on the same service.

Fits

Hope Tech V4 pad shape:

• Hope Tech V4 (the current four-piston generation)

The Tech V4 has a different pad geometry from the older Tech 3 E4 / M4 family; if your Hope caliper is Tech 3-era, the Model 016 is the correct Sinter fitment. The Hope RX2 takes the Model 043. The V4 is identifiable by the newer-generation caliper body shape and the larger pad-pocket aperture compared to the Tech 3 calipers it replaced.

Compound and feel

Sinter's organic ceramic-loaded compound is calibrated for the Tech V4's larger piston area and the more aggressive pad-to-rotor contact pattern it generates. The compound holds its bite at higher pad-surface temperatures than a standard organic, which matters on the V4 because the new caliper design is targeted at enduro and aggressive trail use where pad temperature climbs faster than on the Tech 3 platform. The resin matrix runs quiet on dry rotors, modulates linearly through the Tech 4 lever's progressive feel, and bites cleanly from the first pull.

Sinter's Ljubljana metallurgy, Unior's Zreče forge

Both brands trace back to Slovenian manufacturing: Sinter has been making friction materials in Ljubljana since 1969, and developed the first disc brake pads in the former Yugoslavia in 1972. Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. Euro Toolworks distributes both brands in North America. The Hope Tech V4 is Hope's first new four-piston design in over a decade, and the Model 020 is the pad that fits it.

Pro tip from our mechanics

The Tech V4's larger piston area means a longer pad-bedding window than the Tech 3 calipers most Hope owners are used to. Sinter's bedding instructions cover the standard sequence; on the V4 specifically, expect an extra five or six bedding cycles before the pad seats fully against the rotor. The first ride feels under-bedded; by the third or fourth ride, the brake settles into the bite-and-modulate pattern that's the V4's design intent.
