Avid Rim Wrangler 2 Replacement Brake Pads with Holder
The Avid Rim Wrangler 2 Brake Shoes are for use on front or rear linear pull brakes. Rim Wrangler 2 inserts fit 2001 and newer Avid and other Shimano-compatible pad holders. Includes mounting hardware
These cartridges, paired with a good pair of XT or XTR camming V-brakes would be about the best modulated rim brake you could buy. The cartridge style pays for itself in the long run, once you've put a couple replacements in with almost no setup time and cheaper replacement cost.
Good value. for the money. Solid materials.
