The Trek Fuel EX 9.8 XT Di2 Gen 7 2027 pairs the same OCLV Mountain Carbon frame as the range-topping 9.9 with Shimano's electronic XT Di2 drivetrain — precise, automatic shifting without the SRAM AXS price tag.
WHO THIS BIKE SUITS
- You want a carbon Fuel EX frame without going all the way to the 9.9's price point.
- You prefer Shimano's shift feel and want Di2's electronic precision.
- You're covering serious mileage and want a drivetrain that shifts consistently, ride after ride.
- You want Fox Factory-level suspension performance — this isn't a cut-down spec.
IF YOU'RE LOOKING FOR SOMETHING DIFFERENT
If you'd rather have SRAM's wireless AXS system, the 9.9 X0 AXS is the equivalent tier.
If mechanical shifting suits you fine and you want to spend less, the Fuel EX 9.8 XT (non-Di2) gets you the same frame and suspension for less money.
WHERE IT SITS IN THE RANGE
The Fuel EX 9.8 XT Di2 sits just below the 9.9, sharing the same full-carbon frame and Fox Factory 36 fork, with Shimano's electronic XT Di2 drivetrain in place of SRAM's wireless AXS.
Same tier, other Fuel platforms: Fuel LX 9.8 XT Di2 — Fuel MX 9.8 XT Di2
HOW IT RIDES
Suspension
Fox Factory 36 fork with GRIP X2 damper, paired with a matched Fox rear shock — top-tier suspension performance, well short of the 9.9's price.
Drivetrain
Shimano XT M8250 Di2 shifts electronically at the press of a button — consistent, precise, and low-maintenance.
Brakes
Shimano XT M8220 four-piston brakes give you strong, modulated stopping power.
THE FINAL WORD
The Fuel EX 9.8 XT Di2 is for riders who want carbon-frame performance and premium electronic shifting without stepping up to SRAM AXS pricing. Come in and we'll help you compare it against the 9.9 and the mechanical 9.8 XT.
