SRAM Rival GXP Double Chainset 53 / 39T - 170mm or 175mm
Open Core Technology sounds like something you would find on a spaceship, well SRAM are not far off producing something just as state of the art with their SRAM Rival Crankset (inc GXP cups) 53/39. A crankset that balances weight with stiffness. The Open Core Technology (OCT), compared to conventional solid-core aluminium cranksets, is both lighter and stronger. A standard chainring setup features a 53 outside ring and pairs it with a 39 inner. The addition of GPX cups saves weight and makes for a smoother spinning system.
