Trek Supercaliber 9.8 GX AXS Mountain Bike 2021
Laced with some of the finest technology available, the Trek Supercaliber 9.8 GX AXS Mountain Bike delivers a potent combination of speed and efficiency, helping you propel your way to the top of the podium. At its core, the frame features the class-leading IsoStrut suspension technology, designed in conjunction with FOX to provide 60mm of lockable suspension travel, helping to take the sting out of technical terrain. This is paired with a 100mm FOX 32 Performance Step-Cast fork, which keeps the weight low and the comfort high.
Lightweight carbon Bontrager wheels feature a fast-rolling 29” format - the standard for cross country racing, allowing for rapid acceleration off the line and superlative climbing performance. XR2 Team Issue tyres split the difference between rolling resistance and grip, offering excellent performance on hardpack terrain, while the Bontrager Kovee cockpit optimises your control across all gradients. This model fully embraces technology and features a fully wireless SRAM GX AXS drivetrain, which is easy to set up and customise, issuing tactile shifts across the wide, 12-speed range.
- The Supercaliber is a World Cup-worthy bike that’s quick, capable of soaring through techy terrain and nearly as light as a hardtail
- Trek’s exclusive IsoStrut shock provides 60mm of tunable, damped suspension for a smooth and efficient ride
- Fully-wireless SRAM GX AXS drivetrain offers excellent customisation and tactile performance
- The pivotless seat stays save on weight and actively bend to help soak up trail chatter
- You'll never again have to wonder, "What's faster for this course, full-suspension or hardtail?"
- This specification is race-ready right out the box, featuring carbon GX Eagle cranks and a 12-speed drivetrain
- The FOX 32 Step-Cast fork is a premium choice for cross country performance
- 29” Bontrager Kovee Pro 30 wheels provide a lightning-quick response for rapid acceleration
