The Structure Cycleworks SCW1 is a 27.5" wheeled, full carbon, full suspension, enduro bike built on the most advanced mountain bike chassis in the world. The SCW1 has 150mm of travel at both front and rear. However, due to reduced brake dive - which leaves more suspension travel available for bump handling - the SCW1’s Without Telescoping Fork (WTF) linkage suspension system rides as though it has travel in excess of 180mm.
The WTF front suspension platform solves performance issues inherent to all telescopic suspension forks.
Stability - Head angle slackens throughout travel, with 40% less brake dive, increased trail, and nearly constant front-center early in suspension travel.
Sensitivity - The WTF linkage rotates on 30 mm cartridge bearings and isolates the shock from bending loads, allowing the system to move with minimal friction over bumps large and small with unprecedented control at the contact patch.
Integrated Chassis - The SCW1 features matching leverage ratios and progressivity at the front and rear. Weight and strength are optimized by keeping hollow, carbon, double-crown fork and monocoque carbon control arms low and mounted to the strong core of the chassis.
Size Specific Kinematics - Structure is one of the very few companies that adjusts the location of the shocks and pivots to keep all kinematic properties consistent between chassis sizes.
Practicality - There are no special tools needed to adjust and service the SCW1. Using standard 30mm bearings, anyone who can service a rear shock can service the SCW1.
