Product Details

The Structure SCW 1 is a 150mm travel, 27.5" wheeled, full carbon enduro bike built on the best-handling, most sophisticated mountain bike chassis in the world. The WTF front suspension platform solves performance issues inherent to all telescopic suspension forks. Be among the first to experience the enhanced stability, reduced dive, improved braking performance, and unparalleled bump handling of the SCW 1.

Stability
Head angle slackens throughout travel, with 40% less brake dive, increased trail, and nearly constant front-center.

Sensitivity
A telescoping fork is a stressed chassis element that is asked to slide while subjected to enormous bending loads.
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
Balance between the front and rear suspension is vital to stable and confident handling. The SCW 1 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
The changing location of a rider’s centre of mass from one size to the next can create more performance discrepancy between sizes, for a given model, than between brands. Structure is the only company that adjusts the location of the shocks and pivots to keep all kinematic properties consistent between chassis sizes.

The Foundation

The first 100 private owners (dealers excluded) per model are inducted into The Foundation. Members will enjoy exclusive features and benefits like custom colors and graphics, a numbered Foundation frameset, and much more.

(A) REACH	420	460	505
REACH EFFECTIVE, NORMALIZED FOR STACK When comparing bikes, reach is only meaningful when examined at a constant stack. Effective Reach is the reach value normalized to a stack height that is the average of all current AM/Enduro frames	431	474	522
(B) STACK	634	641	649
(C) SEAT TUBE ANGLE @ HEAD TUBE TOP "Effective seat tube angle" is typically measured level with the top of the head tube, not the rider's assumed seat height. Most seat tube angles become considerably slacker at true saddle height.	77°	77°	77°

SEAT TUBE LENGTH	360	410	465
(E) HEAD TUBE ANGLE	66°	66°	66°
HEAD TUBE ANGLE @ FULL COMPRESSION, COMPARED TO TELESCOPING Compared to a telescoping fork, the WTF linkage design becomes slacker when compressed. Exact value depends on the setting selected.	-7°	-7°	-7°
