SHIMANO – STRX400 GRX 2×10 speed Hydraulic ONLY

Shimano Index System: Every Shimano equipped multi-gear bicycle includes Shimano S.I.S – Shimano Indexed Shifting. It’s the technology behind that “click” you hear and feel every time you shift through your gears. That “click” captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It’s the sound of perfect gear changes, of levers directing derailleurs in harmony, and the feeling that resonates into your hand, letting you know that your commands are being answered.
