Trek Procaliber 6 Red Serpentine

Season:2027

Brand:Trek

Code:80310RED

Procaliber 6 is a cross-country mountain bike built for hot laps and fast singletrack.

It strikes the perfect balance between race-ready and budget-friendly with a modern alloy frame that handles tight corners and rough trail with ease—while still feeling snappy on the climbs. A 12-speed Shimano drivetrain and 120mm RockShox fork deliver all the gearing and comfort you need to keep pushing.

Starting in 2024, Trek began removing high-emission aluminium from manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike Trek makes—this one included—had made the switch, driving a major drop in the footprint.

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.

  • 12-speed Shimano drivetrain
