The 52mm rise is designed to bring the bar up to meet your hands rather than forcing them flat, reducing strain on long efforts and making it easier to hold an aero position for extended periods. Machined from aluminium, these extensions give you a solid, reliable platform without the weight penalty of steel.\u003c\/p\u003e\n\n\u003cp\u003eThe Race Bend profile keeps your hands oriented to avoid the wrist torque that leads to fatigue on sustained rides — whether that's a triathlon, a time trial, or a long training block.
