OCLV Carbon Frame
When compared to metallic materials, a well-constructed carbon frame significantly saves weight while preserving the strength and stiffness required by high performance bicycles and the riders that ride them. This is where Trek’s OCLV Carbon process, which stands for “Optimum Compaction Low Void,” comes into play. Starting with the best material available, OCLV Carbon frames are made. Trek has perfected the manufacturing of numerous weights and types of carbon fibre over the course of countless development hours (cloth, unidirectional, etc.).
The new frame for the Trek Rail 9.8 models including GS AXS, maintains the company’s state-of-the-art OCLV Mountain Carbon fibre for the main frame, along with the company’s venerable rocker-driven single pivot suspension and ABP (Active Braking Pivot) to regulate braking characteristics. The F1-inspired thru-shaft rear shock technology is kept in place to provide reliable damping.
Bosch Performance Line CX motor
With up to 85Nm of torque and a sophisticated eMTB mode with Extended Boost that automatically varies the amount of assist according on the terrain, the Bosch Performance Line CX sets the bar for eMTB performance.
250 watts of power and 85 Nm of torque are claimed for the Bosch Performance CX motor. When you push the pedals, it reacts almost immediately and offers a decent range of assistance thanks to the four output levels of the system. The bike was simple to accelerate to its 20 mph top speed, and switching between output settings was straightforward.
The four modes, Eco, Tour, eMTB, and Turbo, provide 60, 140, 240, and 340% support, respectively.
Bosch Smart System
A very individualised eBike experience is made possible by the clever Bosch eBike Systems system, which consists of the eBike Flow app, control unit, display, rechargeable battery, and Drive Unit. The latest system generation, which combines technically superior eBike components with digital features, raises the bar for riding, whether for daily use or just for enjoyment.
The outstanding Performance Line CX motor with 85Nm maximum torque is complemented by the 2022 Trek Rail 9.8 GX AXS, extremely advanced Bosch Smart System. The fully networked, LED-lit control centre links everything together, automatically updating the software over-the-air, letting the user access a wide range of features and customize the assist mode settings from their phone, tracking activities automatically, and even providing theft protection capabilities. This software offers navigation so you don’t need to add an external cycle computer, and it integrates with third-party apps like Apple Health and Strava to provide them data from your rides.
SRAM Code R 4-piston hydraulic disc
Built to handle everything from electric bikes to enduro and downhill sleds, The Code is SRAM’s high duty brake. To boost power and heat dissipation, each Code brake is equipped with a 4-piston calliper and an extended piggyback reservoir.
These should let you to brake effectively in all weather conditions and offer you the assurance to tackle slick terrain and steep descents without worrying about slipping.
Removable Integrated Battery & Range
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.
The new Trek Rail’s 750Wh Bosch Powertube battery has a 20 percent increase in watt hours over previous models, allowing you to ride longer and harder. Trek Bicycles is still using its RIB (removable integrated battery) system, which makes it simple to remove the battery from the downtube while maintaining security while in operation. With a brand-new 4A charger, this battery can be fully charged in six hours and will reach 50% capacity in just two hours. Intelligent battery management prevents overloading and maintains good battery health.
Check out Bosch’s range calculator to determine how far you can travel on an electric mountain bike with one charge. You can make changes to achieve your most precise estimate even if we’ve pre-filled the data for this bike model and the typical rider. Calculate your range here.
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.
RockShox Super Deluxe with Thru Shaft
With the brand-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most sophisticated shock on the market, with an upgraded air spring and a special Thru Shaft damper that gives you tenacious grip, velvety control, and the support you need for ripping hard descents all day.
Custom eMTB Lite mode
Instead of a Tour mode, Trek eMTBs have a unique eMTB Lite mode. You get longer battery life and more natural-feeling power delivery.
Oh! What a feeling
With a new Bluetooth-connected LED remote and the eBike Flow app, Bosch’s updated smart system gives you the same amount of power and responsiveness while giving you even more control and customization options.
The redesigned frame is more durable, with a 34.9mm seat tube to accept dropper posts that are more robust and a bigger head tube that works with forks designed specifically for eMTBs to reduce flex and improve 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.
The full-color Kiox display provides ride information and may connect to Bluetooth®-enabled devices. It also has an integrated theft protection feature.
