This item is currently not available.


E-Caliber 9.8 GX AXS is a lightweight carbon electric mountain bike that rides—and looks—like a traditional cross country bike. It's built with the same race-worthy tech as Supercaliber, including our exclusive IsoStrut integrated shock, and it has a sleek Fazua drive system that delivers a little boost when you want it most. You also get a GX Eagle AXS wireless electronic drivetrain for blazing-fast shifts.

It's right for you if...
You're an avid XC rider, and love the idea of an e-MTB that helps you push your limits without providing too much assistance. It's also great for those who want to get out and ride more, or keep pace with faster friends.

The tech you get
A lightweight OCLV Mountain Carbon frame with 60mm of travel, a 120mm RockShox SID Select+ fork, and Trek IsoStrut shock. A Fazua Evation motor and 250Wh battery that can assist up to 20mph when it's on and gives zero drag when it's off. A SRAM GX Eagle AXS wireless electronic drivetrain, Bontrager Line Elite dropper post, and wider Kovee Pro 30 carbon wheels with a 108-tooth Rapid Drive rear hub for instant engagement.

The final word
E-Caliber flies down singletrack like an XC MTB—because it's modeled after Supercaliber! The Fazua drive system provides a just-right amount of assist, and SRAM's newest wireless electronic drivetrain ensures every shift is crisp and ultra-fast.

Why you'll love it
- You get a helping hand from the motor on climbs and long rides, but it's a more natural-feeling assist that gives you an overall experience that's closer to riding an analog bike than a typical e-MTB
- The drive system, including the motor, is easily removable. Just take it out, pop on the included cover, and you'll have a standard mountain bike that weighs 2.9kg less than before
- The SRAM GX Eagle AXS drivetrain is smart, smooth, and completely wireless
- IsoStrut gives you just enough rear suspension for cross country traction and comfort with less weight and more efficiency
- Pivotless seat stays save on weight and actively bend to help soak up trail chatter
