What Is the Shimano M70R2 BR-M770 Cartridge Shoe Set?

The M70R2 BR-M770 cartridge shoe set is the complete shoe-and-pad unit for Shimano's XT-grade V-brake caliper system, sold as a single pair. Unlike the replacement compound inserts sold separately, this listing includes the full cartridge-type aluminum shoe holder along with the M70R2 severe condition compound insert pre-installed. This makes it the correct option for riders who need to replace worn or damaged shoe holders entirely, not just swap the rubber compound. The aluminum holder mounts directly to the V-brake caliper arm via the standard threaded post and adjusts for toe-in alignment. The M70R2 severe condition compound is formulated for consistent grip on aluminum rims in wet, muddy, and gritty conditions.

This shoe set is compatible with Shimano BR-M770 XT V-brake calipers and other Shimano V-brake calipers that use the standard cartridge shoe post format. The M70R2 compound delivers reliable stopping power in all-weather commuting and trail conditions, where standard compounds can glaze or wear unevenly. Replacement is straightforward: remove the old shoe from the caliper post, install the new shoe unit, set toe-in and rim alignment, then tighten. The cartridge shoe design allows future pad replacement using M70R2 inserts without replacing the holder again. For riders running XT V-brake setups who need a complete shoe and pad replacement rather than just a compound swap, this is the correct complete unit.
