One and done.
The SRAM Force 1 Hydraulic Left Brake Lever/Caliper is the perfect accompaniment to 11-speed Force 1x groupsets. It has the same ergonomics and carbon lever as the Force 1 hydraulic front shifter but deletes the shifting mechanism for a sleek, lightweight design. It's paired with a post-mount Force brake caliper with easy-access bleed port and steel-backed organic pads for easy service and confident stopping power.
Claimed weight is 471 g (including 160 mm rotor, sold separately). Caliper is compatible with both post and flat mount adaptors. Rotor not included.
