Why shouldn't young riders benefit from the advances happening in adults mountain bikes? We're proud to introduce the Brood Bike Co. Styx Crank - an industry first for the smaller crowd. These two piece, through axle cranks are compatible with direct mount chainwheels with the common SRAM interface and GXP spacing. This opens up a new world of options from the more common 4-arm 104mm BCD cranks of the past which are typically limited to 32t chainwheels as a minimum. With these new cranks, any chainwheel with a SRAM GXP interface will work, meaning you can go anywhere from 26t to 36t and add narrow wide functionality with widely available aftermarket chainwheels. Cranks come complete with bottom bracket, spacers and fixing bolt to fit a 68/73mm bottom bracket shell. 49mm chainline.
