It runs a 50x34 compact configuration — a versatile gearing spread that handles everything from punchy group rides to hilly training routes. At 165mm, this crank variant suits riders who prefer a shorter arm length for comfort or biomechanical fit.\u003c\/p\u003e\n\n\u003cp\u003eShimano builds the RS520 with the same design discipline that runs through their broader road lineup.
