Trek Procaliber 6 Mountain Bike 2020
The Trek Procaliber 6 Mountain Bike is a great way into cross-country racing or fast trail riding. The hardtail aluminium frame uses IsoSpeed technology to offer much more compliance than most hardtails without reducing the stiffness required for efficient power transfer, making it both comfortable and rapid. The RockShox Judy Gold fork has 100mm of travel but can be locked out completely from the handlebar switch for sprinting or smooth climbs.
The componentry is supplied by SRAM and Shimano, with SRAM’s 12-speed, single-ring drivetrain operated by an SX shifter and NX derailleur whilst the hydraulic brakes are Shimano MT400s. In order to provide more consistent handling across the size range, the smaller sizes use 27.5” wheels whilst the larger sizes have 29” wheels, but all are tubeless-ready for lower rolling resistance and greater puncture protection.
Highlights
- Alpha Platinum Aluminium frame, with internal cable routing and IsoSpeed
- RockShox Judy Gold fork with 100mm travel and remote lockout.
- SRAM SX/NX 12-speed groupset
- Shimano MT400 hydraulic disc brakes
- Smart Wheel Size, size S and M designed for 27.5”, larger sizes use 29”
