Shimano Ultegra R8010 Brake Caliper

Direct mount means the caliper bolts directly to the frame or fork rather than using a single central bolt. This design increases stiffness and improves braking modulation, but you must ensure your bike frame is specifically designed to accept direct-mount brakes.

These calipers are only compatible with frames specifically engineered for direct-mount brakes. They will not fit on a standard frame that requires a traditional single-bolt center mount.

The Ultegra R8010 series uses higher-grade materials and tighter tolerances compared to the 105 series. This results in a slightly lighter weight and a more refined, responsive feel at the lever.

The R8010 series is generally optimized for standard road tire widths up to 28mm. If you are running wider tires, you should verify your frame's specific clearance, as the brake caliper itself is not the only limiting factor.

The R8010 series includes specific versions for both front and rear placement. Ensure you select the correct version for your bike's mounting location, as the bolt spacing and cable routing differ between the two.
