Trek Rail 9.9 XTR
Rail 9.9 is a long-travel electric mountain bike built for ultimate trail performance. The light OCLV Mountain Carbon frame features an awesome RockShox suspension setup, a full Shimano XTR drivetrain, and the best e-MTB drive system on the market. It'll shred right alongside the enduro crowd, but the best part is that you'll always beat them up the climbs and get in the most runs.
It's right for you if...
You're looking for a seriously capable long-travel carbon e-MTB and you want nothing but the best. Your bike better have a top-of-the-line drivetrain, a high-end suspension setup, and a powerful Bosch system that'll fly up grinders in a flash.
The tech you get
A light and durable OCLV Mountain Carbon main frame with alloy stays that fully encases a 625Wh battery for sleek looks and protection on the trail, a 160mm RockShox Lyrik Ultimate fork with Charger 2.1 RC2 damper, 150mm of rear travel with a RockShox Deluxe RT3 shock with Trek's RE:aktiv with Thru Shaft damper, a powerful new Bosch Performance Line CX 250W motor that assists up to 20 mph, and a Kiox controller. A 1x12 Shimano XTR drivetrain, Bontrager Line Elite dropper post, 4-piston brakes, a carbon handlebar, and Bontrager Line Carbon 30 29er wheels with Bontrager SE5 Team Issue tires.
The final word
Rail 9.9 is all about top performance tech. RockShox's best enduro fork, Bosch's most powerful battery, latest motor, and full-color controller. Plus, the light OCLV Mountain carbon frame is trimmed with lots of carbon parts, including the wheels and handlebar.
Why you'll love it
- The new, better-than-ever Bosch motor is smaller, lighter, and more efficient. It feels more natural while you're pedaling, and has less drag when you're not
- The full-color Kiox controller displays ride info, connects with your Bluetooth-enabled devices, and has a built-in theft prevention feature
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- 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
- Made with the same exclusive frame tech as Remedy and Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
