The Dia-Compe BRS101 is a long-reach caliper brake built for bikes that need a little more depth between the brake arm pivot and the rim — think vintage road bikes, city bikes, and anything running larger tyres or wider clearances.
With a reach of 43–57mm, the BRS101 goes deeper than a standard caliper while keeping things tidy with a dual-pivot design for consistent, even braking power. The arms are cold-forged aluminium, which keeps weight down without sacrificing strength, and the BRS index quick release makes wheel removal straightforward.
