Improving upon Shimano’s lightest post-mount offering, the XTR XC BR-M9200 two-piston post-mount caliper is equally at home on the World Cup cross country circuit when paired with BL-M9200 lever, or on rougher, steeper trails with the BL-M9220 Enduro/trail lever (levers sold separately). Heat-resistant resin caliper pistons, metal pads, and new low viscosity mineral oil make the M9200 caliper the ideal option for any two-piston brake requirement
