What are SRAM Titanium Flat Mount caliper bolts used for?

The SRAM Flat Mount Titanium Disc Caliper Bracket Bolts at 37mm are T25 Torx titanium bolts used to mount flat mount disc brake calipers to frame and fork flat mount interfaces. Titanium hardware at the brake caliper is a meaningful weight savings over the standard stainless steel bolts on a part that sees significant torque and vibration loading. Titanium provides the necessary strength with lower mass and natural corrosion resistance that makes it well suited to a structural fastener exposed to weather and road spray. The 37mm length is the correct spec for specific flat mount configurations where additional bolt length is needed, typically rear caliper mounting with certain adapter or frame geometries.

Compatible with SRAM flat mount calipers including the full eTap AXS road hydraulic disc lineup, covering RED, Force, and Rival, as well as any flat mount caliper using the standard T25 Torx interface. Use a torque wrench and follow the caliper manufacturer's specified torque value to seat these bolts correctly. Under-torquing flat mount caliper bolts leads to caliper movement and pad rub under braking load. If your mounting configuration requires 32mm bolts, the 32mm titanium version is also available. These are caliper bracket mounting bolts and are not to be confused with disc brake banjo fitting bolts or rotor mounting hardware.
