Galfer Lightweight Aluminum Flatmount Caliper Adapters (for Road & Gravel Disc Brakes)

In today’s road and gravel scene, marginal gains matter. The Galfer SB006 and SB007 aluminum Flatmount caliper adapters are engineered for riders who demand precision, weight savings, and uncompromised braking alignment in disc-specific setups.

The front SB006 introduces an innovative axial caliper adjustment system — a rare feature in the market — allowing millimetric positioning of your brake caliper. Once dialed in, the alignment remains consistent even after removal and reinstallation. For mechanics and performance-focused riders, this means faster service time and perfectly centered braking every time.

Both models are CNC-perforated to reduce excess material while maintaining structural integrity. Whether you're upgrading to a 160 mm rotor or optimizing a lightweight race build, these adapters deliver reliable stopping power without unnecessary grams.
