Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
