SRAM DB8 Disc Brake positioned as a high-performance option for enduro and trail riding is a very impressive option for us thanks to its simplified design that delivers serious stopping power at an entry-level price. This is SRAM's first mineral oil brake system. which provides 90% of the stopping power of top-tier RSC code disc brakes at a fraction of the cost. Why mineral oil? Thanks to the SRAM fluid switch, the DB8 brakes only need to be bled every two years and all other SRAM brakes must be bled at least once a season.
