For years, SRAM's Code brakes were the go-to for everyone from recreational shuttle lappers to competitive gravity nuts. The latest generation of Code R Disc Brakes doesn't change the reason why; instead, it reinforces it by adopting the same cam mechanism that made the Guide models such big hits among the all-mountain crowd. The cam's excellent modulation is paired with a larger reservoir and pistons in order to increase stopping power for applications that need it--think gravity rigs, e-bikes, and anything else where weight isn't a consideration. The reworked Code R is a big brake for big rigs.
