Rail 9.9 X0 AXS T-Type Gen 4

• Carbon Rail Gen 4 has the same enduro-inspired geometry and huge battery as the previous generation, but now it has a pocket in the top tube that makes Gen 4 compatible with Bosch’s integrated System Controller and Mini Remote
• Its clean cockpit is minimalist and sleek, and smart system makes it easy to add a display if you want more data
• Intelligent eMTB and Tour+ modes automatically adjust the assist based on your input to give you just the right amount of power for your ride
• SRAM's direct-mount T-Type wireless transmission delivers next level performance with precise shifts under load and unmatched durability
• Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools, and lets you mount a water bottle cage
