Presenting the scw1 Enduro carbon full linkage chassis

150+ travel front and rear.

The most significant evolution in mountain bike chassis design since rear suspension.

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. From enduro racers to weekend warriors a confidence inspiring bicycle that makes your ride faster and more enjoyable. Read on and discover how this design solves current suspension problems to increase your confidence and control in all conditions.

The WTF front suspension platform solves performance issues inherent to all telescopic suspension forks.

Design Features

Integrated Linkage Frame

Balance between front and rear suspension is vital to stable and confident handling. The SCW1 features matching leverage ratios and progressivity 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.

Friction Reduction

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 while offering unprecedented control at the contact patch.

Why

Telescoping forks come with compromises that negatively affect the performance of the whole bike. Structure’s WTF (Without Telescoping Fork) suspension system solves these problems and delivers massive improvements in ride, handling, and at-the-limit performance, with up to a 40% reduction in dive under braking. 

Increased stability

As the telescoping fork of a typical bike compresses, head angle becomes steeper and wheelbase and trail are reduced, resulting in decreased stability. Our WTF system does the opposite. During compression, the head angle slackens, trail increases, and there is less wheelbase reduction, resulting in a significantly more confidence-inspiring ride and a faster bike.

Geometry

Low standover, long dropper posts, and proper component selection and setup allow us to fit more riders than ever. Select your SCW1 frame size according to riding style rather than saddle height and reach.

The changing location of a rider’s centre of mass from one size to the next can create more of a 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.

In the same way you might choose the length of your skis or snowboard to reflect your preferred terrain and riding style, our short seat tubes allow you to tailor your SCW1 to your riding. We call this “Gravity Sizing”. Instead of sizing according to riders’ body sizes with Small, Medium, and Large, we give each chassis a Gravity rating (ex. G2) to denote the level of stability. Please refer to the geometry chart for full details and contact us for assistance with your selection.

Weight

“How much does it weigh?” We hear that question often. Depending upon component selection, we are working closely with our factory to keep weight to 32 pounds for the full-carbon SCW1, similar to the weight of our alloy bike.

Development

Our alloy test bike features adjustability at nearly every pivot, taking the place of several non-adjustable prototypes. We took lessons learned from years of hard riding and a data-driven design process to offer geometry and kinematics that are even more ahead of the curve than they appear.

PROOF OF CONCEPT: Structure’s alloy prototype starts with a head angle of 69.1° and becomes slacker throughout its travel, gaining 50% more trail. It is also adjustable for anti-dive, going from plush to racy with a flip of an eccentric.

PRE-PRODUCTION PROTOTYPE: Structure developed a rapid prototype to check the aesthetics and fit before finalizing the design. We obsess over the smallest details.
