A 1x12 SRAM X01 Eagle AXS drivetrain, RockShox Reverb AXS dropper post, Shimano XT 4-piston brakes, a carbon handlebar, and Bontrager Line Carbon 30 29er wheels with Bontrager SE5 Team Issue tires.
The final word

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.
- The SRAM X01 Eagle AXS drivetrain is smart, smooth, and completely wireless.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
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.
