The hollow-construction crank arms deliver a stiff platform for efficient power transfer while keeping weight in check, and the finish is a clean matte black that holds up to the kind of riding gravel roads demand.\u003c\/p\u003e\n\n\u003cp\u003eAvailable in 38t and 40t chainring options, the RX610 crankset is designed to pair with wide-range cassettes — \u003cstrong\u003e10-45t or 10-51t\u003c\/strong\u003e — giving you the gear spread to climb steep gravel climbs and carry speed on open roads.
