Trek E-caliber 9.8 Gx Gen 2 Mountain Bike
Fast and efficient
Fazua’s lightweight drive system adds a punch of power when you need it, but rides and feels like a traditional bike when you don’t. You won’t feel much drag or resistance when you turn it off or pass the max level of assist. The system is also compatible with a smartphone app to let you check battery status and customize your ride.
Smart software for the trail
E-Caliber is equipped with intelligent Fazua software called BLACK PEPPER, which allows the motor to respond immediately as you start to pedal, delivers more power over a wider cadence range, and lets you customize your user settings.
Removable drivepack
Remove the motor and drivepack to save 6.4 lbs./2.9 kg on days when you don’t need the boost. The included cover also turns the down tube into extra storage.
IsoStrut
E-Caliber has the same innovative IsoStrut rear suspension as World Cup-winning Supercaliber. You get 60mm of integrated rear travel—just the right amount of comfort and traction, without the weight or flex of traditional full suspension.
OCLV Mountain Carbon
Trek’s mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek’s advanced engineering, and a higher standard of testing.
