Shimano, Front Chainwheel, Fc-Ty501-2, 7/8-Speed, 170Mm, 46-30T W/O Chain Guard, Chain Case Not Compatible, Black

The Shimano FC-TY501-2 is a durable 46-30T double chainwheel from the Tourney line, designed for 7/8-speed mountain, hybrid, and touring drivetrains. It uses Shimano's Hyperdrive chain-control design, pairing purpose-shaped tooth profiles and chain pickup ramps with a wide-link front derailleur and HG chain for smooth, precise indexed front shifting even under demanding conditions. This 170mm crank arm variant has a square-taper spindle interface and is built without a chain guard, making it a reliable, affordable replacement or upgrade part for entry-level bike setups.
