Internationally patented and quantifiably the most energy-efficient suspension design in the World, ICT tuned four-bar linkage design provides a true zero-energy loss to suspension function. By aligning the instant center on the chain torque line and continually tracking the chain torque throughout the range of travel, ICT is accomplished without the need of a lockout. This keeps the suspension fully active and always on, resulting in increased traction and control, and reduced rider fatigue. ICT suspension is internationally acclaimed and continues to set the bench mark for suspension performance.

One of the most highly engineered parts on Ellsworth full suspension bicycles, the asymmetrical, CNC machined chain stays have been scrutinized and minimized to provide an incredible strength-to-weight ratio. This section is precision aligned to maintain proper wheel tracking and strict, unencumbered suspension movement. The geometry, combined with ICT, moves the precision bearings further apart which acts to stiffen the tail section and
minimize bearing play.

Ellsworth's full suspension bikes utilize a carefully developed attachment system of oversize bearings with the seats and housings, resulting in only a SINGLE bolt-per-pivot assembly. In addition to ensuring accuracy and flawless articulation of the suspension without flex, slop, or binding, the sex pin reduces the need for multiple parts, keeping the Ellsworth full suspension bikes durable, easy to maintain and simple.

Our tubes have been optimized for strength, rigidity, weight, and tube joint interfaces. The tubes are tapered, swaged and shaped providing more control over the precise wall thickness that occurs when the tube takes its final shape. SST.2 tubes transmit all the possible torque a rider may dish out, while maintaining alignment of critical suspension points to ensure the best possible ride.

Prior to welding our frames, each tube is milled by hand to align exactly in position before welding. Each tube is then welded around the entire interface, without gaps, for maximum strength and to improve overall efficiency by eliminating unwanted frame flex. This meticulous practice eliminates creaks, extends the life of the frame and provides durability.

DMS (Dual Mono Stay) firm tail design, has the following benefits: smoother ride, having the capability of dampening the resonance characteristics of the road, through force direction carbon design and tube energy transfer and damping. It also has the versatility and strength capable of supporting single speed configurations, as well as multi-gear chain drive options, and gearless NuVinci. It’s more then just a pretty carbon frame—it has years of versatility, and strength built into it.

Ellsworth spent three years qualifying our carbon fiber manufacturing facility, material and technique. Our carbon material is certified and tracked from its creation and acquisition through the lay-up in our frame molds, preventing any substitution in material specification or deviation in production from the design specifications. Our state-of-the-art manufacturing facility exercises social responsibility and properly controls the dissipation of carbon particulate in the finishing process through near net molding technique.
