Tech YOU GET
An updated OCLV Mountain Carbon frame for optimal strength, featuring a longer reach and larger head tube and seat tube. RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock, and SRAM XX1 AXS drivetrain are all highly adjustable. The battery has an extra-long range of 750 Wh. With the new Bluetooth® LED remote for simple connectivity, the eBike Flow app’s all-in-one navigation and activity tracking, as well as TyreWiz and AirWiz pressure monitoring, you get Bosch’s new smart system Performance Line CX.
THE LAST WORD
High-end tech is the focus of The Rail 9.9. The greatest enduro fork from RockShox, the largest battery from Bosch, XX1 AXS’s smooth shifting, an updated frame, pressure monitoring from TyreWiz and AirWiz, and the newest tech from Bosch with a smart system.
Why You Will Enjoy It
With a new Bluetooth-connected LED remote and the eBike Flow app that allows you, even more, control and customizability, Bosch’s new smart system give you the same power and responsiveness.
With the aid of TyreWiz and AirWiz, you can quickly determine whether the pressure in your tires, fork, and shock is appropriate. No need to remove the pump or gauge to check anything
Because RE: aktiv with a Thru Shaft operates more quickly than a typical shock, it tracks the ground better and maintains control.
A 34.9 mm seat tube on the new framework allows for more sturdy dropper posts, and an enlarged head tube pairs with extra eMTB-optimized forks for less flex and more precise steering.
The Trek Removable Integrated Battery (RIB) system is incredibly user-friendly and stylish. It protects the battery by completely encasing it in the frame, makes it simple to remove the battery without any tools, and allows you to mount a water bottle cage.
