Those that ride, Know!

CLASSIN’ IT UP SINCE 1991 Since 1991, we have been designing, handcrafting, and most importantly, RIDING bikes. Mountain bikes, road bikes, commuter bikes - you name it, we create it AND ride it. Ellsworth Handcrafted Bicycles are unique, award winning and the American craftsmanship has been compared to a work of art. Although very flattering (we must say), we just design and handcraft bikes to create the ULTIMATE rider experience. From the moment the first sketch is drawn, to the final product arriving at our Independent Bike Dealers, we always have three key design imperatives driving the end result: Energy Efficiency—for climbing, speed and acceleration; Ride Quality—incredible handling, traction and control; and Reduced Rider Fatigue—for sustained physical performance. Ellsworth riders simply go further, faster, using less energy. Who wouldn’t want that? In addition to our obsession with anything that pedals, we are also dedicated to social responsibility and environmental stewardship. Headquartered in a sustainable building that is powered by the sun and the wind, we also donate proceeds from specific frame sales to forest conservation efforts and the fight against cancer. We celebrate our 20th Anniversary in 2011 and look forward to many years to come of innovation, dedication and last but certainly not least, RIDING inspirational bikes.

Instant Center Tracking™ (ICT)

Asymmetrical Void Hollow Chain Stay

Shaped, Swaged and Tapered Tube Set (SST)

Circumferential Tube-to-Tube Welding

Ellsworth Factory Tuned Fox Front Fork and Rear Shock

Optimized ChainLine

NEW Semi-Integrated Tapered Head Tube

CNC Machined Derailleur Hanger

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.

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.

With 20 years in the business of suspension tuning, Fox painstakingly custom tunes Ellsworth’s rear shocks with our specific original equipment forks to create the ultimate matched ride characteristics. Utilizing Fox’s tapered steer tubes; we maximize the stiffness and weight advantages on our frames with our new semi-integrated, tapered head tubes. The suspension performance advantages are showcased by the Ellsworth Frames unparalleled pedal-ability.

The tapered head tube provides superlative strength for razor sharp handling and increased front end stiffness. It improves the overall stack height and allows for an increased bearing surface. This triangulated design, coupled with a lightweight semi-integrated headset, provides the utmost in steering control and handling technology.

NEW Super-formed Pivot Integrated Seat Tube

By utilizing heat to prepare the aluminum in the mold, we better control the flow characteristics of the material over conventional hydro-forming, thus maintaining control of the wall thickness in the shapes. New super-formed seat tubes are lighter and stronger than ever.

CNC Machined Rockers

MASTERS OF THE CRAFT

So often we’re asked what’s better: carbon, aluminum, Ti, magnesium, steel, bamboo…? Our answer is always the same. It’s not the material, it’s what’s done with it. At Ellsworth, we call this Material Management. Whether we are crafting our U.S. frames or working with our carbon manufacturer on design specifics, we manage each material we use from start to finish. Exploiting the material’s unique strengths and eradicating its weaknesses with specific design solutions.

Optimized for precision, free-moving linkage performance, Ellsworth’s CNC Machined Rockers also contribute to increase overall stiffness. Critical measurements are robotically monitored, assuring the lightest, strongest and incredibly precise machined parts.

Custom 12mm Sex Pins

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.

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.

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.

By working closely with component manufacturers and using aerospace technology in our pivot joints, Ellsworth Handcrafted Bicycles are designed to align our chain to Shimano or SRAM’s exact specifications. Each component of the rear triangle is designed in mind of this critical alignment which reduces drivetrain drag, improves shifting, and overall rider efficiency.

Even the most cautious riders know that accidents happen, and on a bicycle that usually means a bent or broken derailleur hanger. Each Ellsworth model is designed with the capability to replace the derailleur hanger. Our Enlightenment models also offer alternate dropouts, for single speed or fixed configurations, in addition to running the latest conventional drive trains.

Anodized FinishING

Carried out under Portland, Oregon’s strict environmental control regulations, the anodized finish protects the frame, inside and out, from condensation and other factors, while preventing detrimental fatigue corrosion. Anodizing is done by hand and creates a unique, one-off finish that is durable and less prone to scratching and wear than paint. Our anodizing process also showcases the flawless craftsmanship of an Ellsworth frame, without covering up flaws and imperfections.

Rare Earth Carbon™ Fiber Processing

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.

Force Vector Anisotropic Design™

(Carbon Composite Frames) Carbon fibers are stranded in a single orientation that creates an anisotropic property (a material with different strength characteristics in different directions). This material attribute can be detrimental to the finished product if not characterized in design, engineering and production. Ellsworth has extensively tested and analyzed force-vectors in bike frames for over 20 years of cutting-edge frame production. The result is an enhanced life and feel of the finished bike frame. Utilizing the unique character of anisotropic material management, Ellsworth creates astounding performance from its Rare Earth Carbon Composite frames.

SPECIFICATIONS XCR XC TR AM SS 4X FR DH The legendary performance of the 100mm travel Truth sst.2 has been enhanced through fine tuning and tweaking over countless seasons of XC and endurance racing, in every condition imaginable. With Ellsworth’s proprietary ICT suspension, SST tubing, a NEW lighter and stronger pivot integrated seat tube and a NEW semi-integrated tapered head tube - this is the fastest Truth ever created. From the Costa Rican mud and rainforest jungle of the La Ruta de los Conquistadores race, to the sands of the Mohave Dessert, this bike is the number one choice of privateer racers. While factory folks are paid to ride what they have to, privateers choose their equipment carefully and it must make them their best. The Truth has done just that for almost two decades—and this year’s Truth is better then ever. There are lots of bold claims out there, but how many of those have held up to two decades of consistently delivering on those claims? Truth—the name says it all.
