Is the Trek Fuel EX 9.8 XT Di2 worth $4,488.88?

If you want a carbon trail bike with electronic shifting and 145 mm of travel, it is a fair price for that build. Riders on a budget can get similar travel with a mechanical drivetrain for less.

How does the Fuel EX compare with the previous generation?

Reviewers describe it as a big generational leap, with more modern geometry and capability. It is the better choice unless you find a steep discount on the older model.

Can I run mixed wheels on the Fuel EX?

Yes, it supports an MX setup, but you need additional hardware that is not part of the standard build. Budget for that if you want a smaller rear wheel.

What is included in the 9.8 XT Di2 build?

The build includes a carbon frame, 150 mm fork, 145 mm rear shock, Shimano XT Di2 12-speed drivetrain and hydraulic brakes. Confirm the exact spec with the store, since build parts can vary.
