STR-40 Trophy caliper, 26/30mm pistons, natural anodized finish, 28mm wide rotors, trailing left.

IMPORTANT NOTE: This Gen5 caliper supersedes earlier calipers with 28/28mm pistons. The 4mm stagger between leading and trailing piston diameter helps eliminate tapered pad wear. The new piston sizing increases clamping force slightly, so these calipers must be used on both sides. Do not mix with earlier generation calipers.
