ENVE's IN-Route System is designed to hide hoses and wires from the wind, improving the bike's aero performance with a practical and user-friendly solution. This doesn't come at the expense of limiting drivetrain options - the RD, AR, and GRVL IN-Route forks, bars, stems, spacer, and headset options are compatible with most drivetrain brands, models, and configurations on the market. As a complete system, IN-Route provides a variety of headset, stem, fork, and one-piece bar/stem combos to get the right fit for any frame material or rider size. Similarly, the headset components and spacer design simplify stack adjustment. These features make IN-Route a complete top to bottom solution for cable/hose integration.
