Elegant internal cable management

Internal cable routing provides a clean look and effectively protects cables from external influences. It also reduces air resistance, allowing for a more aerodynamic and quieter ride.

27.5" wheels for confident off-road riding

Large 27.5" wheels easily overcome uneven terrain. Thanks to the larger contact area with the ground, the bike effortlessly overcomes obstacles like rocks and roots, minimizing shocks and preventing lateral slippage. The design effectively absorbs vibrations, providing greater comfort.

Locking front shock absorber for flexible adjustment

The mechanical locking front shock absorber with adjustable oil spring adapts to various surfaces. It provides greater stability on uneven terrain, and can be locked for flat trails to conserve energy if necessary.

Lightweight aluminum frame – durable and agile

The high-quality aluminum alloy frame combines low weight with high stability. It improves acceleration and climbing efficiency, which is noticeable both on hills and on long rides – without compromising durability.
