TREK 2021 Rail 9.8 XT

The Rail 9.8 is a long-travel carbon electric mountain bike that rips just as hard as our beefiest trail rigs and powers you straight back up the mountain. It features amazing upgrades to the suspension, drive train and brakes for exceptional performance on the gnarliest runs.

You're looking for a long-travel carbon e-MTB with high-performance parts. You crave the responsiveness of carbon, the plush feel of high-end suspension, and would rather get all the good stuff now than have to upgrade down the line.

An OCLV Mountain Carbon frame that fully encases a 625 Wh battery, a super responsive RockShox ZEB Select+ fork with extra-burly 38 mm stanchions and loads of adjustability, a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a Bosch Performance Line CX 250 W motor that assists up to 20 mph (25 km/h in Europe) and a Kiox controller. A smooth-shifting Shimano XT drive train, 4-piston brakes for confident descents and Bontrager Line Comp 30 29er wheels with robust SE5 Team Issue tyres that come completely tubeless-ready, including sealant.

This bike features across-the-board upgrades that make it a serious ripper - especially the suspension package. It's built for hammering gnarly descents, then flying right back up again thanks to the powerful Bosch drive system.
- The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you're pedalling, and has less drag when you're not
- The full-colour 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
- 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)
- 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
- Smaller frames (S) have a top tube that dips down as it approaches the seat tube

New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller and quieter than previous versions, for cleaner integration and more nimble handling. It's also more efficient so you can go further on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.

Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.

Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It's the most convenient way to remove your battery for transport, security or just easier charging.



Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.



OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.



RockShox Super Deluxe Thru Shaft damper
With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control and the support you need for ripping rough descents all day.
