Technology Highlights

Unidirectional Carbon Fibre Frame

The Alpine Trail Carbon models feature high modulus carbon fibre construction and monocoque manufacturing to create a lightweight, stiff, and extremely durable frame designed for demanding trail and enduro riding.

Series 4 Aluminium Rear Triangle

The Series 4 aluminium rear frame uses advanced forging techniques, optimized tubing, and full internal cable routing to provide a strong and reliable platform with premium performance characteristics.

One-Piece Forged Rocker Link

The heart of the MultiTrac suspension system is the forged one-piece rocker link. Its increased stiffness keeps the rear wheel tracking accurately while providing smooth and controlled suspension performance under heavy loads.

Bridgeless Seatstay Design

The stiff one-piece rocker design allows for a bridgeless seatstay construction, improving tyre clearance while maintaining excellent frame stiffness and durability.

Modern Enduro Geometry

The Alpine Trail features a slack 63.5° head tube angle combined with a steep 78° seat tube angle and long reach measurements. This geometry improves climbing efficiency while providing maximum confidence and stability on steep technical descents.

Sizing & Selection

Choosing the correct bike size is essential for comfort, control, and performance. The Alpine Trail’s modern geometry is designed to provide a balanced riding position for aggressive trail and enduro riding.

Use the geometry chart above to compare reach, stack, and frame dimensions. Riders between sizes can choose based on their preferred handling characteristics:

• Smaller size: More agile and playful handling
• Larger size: More stability and confidence at higher speeds
