We’ve been big fans of the Guide brake since it’s launch in 2014,  and have been running two sets with zero problems, not including brake pad swaps and a replacement hose on one brake from crash damage. We’ve not had to go near them with a bleeding kit either, which is a huge bonus seeings as the predecessor – the Avid Elixir – was prone to ingesting air via the Taperbore system.

A 2014 SRAM Guide RSC brake – still being used with no issues to date

Brand new for 2015, is the new Guide Ultimate, which heads the range up as the all-singing and dancing model.

It uses a 4-piston S4 caliper; Swinglink lever cam and carbon lever blade and weighs just 360grams. There are new features for better heat dissipation and management, which help offer more consistent braking in a variety of conditions.

The new caliper incorporates a redesigned seal and aluminium piston interface for ease of set up, and improved consistency – and the new Bleeding Edge system simplifies the older time-consuming and somewhat messy bleeding method.

• Pistons diameter: two 14mm and two 16mm pistons for power and modulation

• New seals, gland geometry and piston coating for improved rollback, results in easier setup and improved consistency.
