2016 sees Ellsworth celebrate 25 years of making mountain bikes, and its new carbon Rogue Sixty is as about as modern as it gets with a long, low and slack geometry, 27.5in wheels and 160mm of travel on both ends.

Ellsworth Rogue Sixty frame and equipment
27.5in wheels and 160mm of squish put the Rogue Sixty directly in the enduro market. The geometry sits long, low, and slack, and the single ring Shimano XT crankset is helped by an MRP chainguide held on by ISCG05 tabs.

Rear end suspension action is handled by Ellsworth’s Active Energy Efficient Suspension. It’s the latest iteration of Ellsworth’s ICT (Instant Center Tracking) design, which Tony Ellsworth has been refining for over 17 years.
The promise was of no anti-squat, just pure acceleration and forward momentum coupled with spot-on bump absorption
It’s a fully active, four-bar linkage that prizes traction and efficiency everywhere, especially over challenging, technical terrain where most riders typically coast.
Rear-end stiffness comes from the Hex Key ‘Rocker Locker’, which is a proprietary shock bolt and link interface to keep the bike tracking solidly. Aiding in the quest for overall rigidity is a hex-taper rear axle, dual row angular contact sealed bearings, and wide, machined threaded pivot bolts.
Shimano’s XT and Fox’s Factory suspension performed as expected, which of course means utterly brilliant.
Ellsworth Rogue Sixty ride impression
Before going out into Boulder City, Nevada’s harsh, ruggedly rocky desert singletrack, I spent some time talking with the man himself, Tony Ellsworth. He encouraged me to try pedaling through technical sections of trail where I would normally coast.
The promise was of no anti-squat, just pure acceleration and forward momentum coupled with spot-on bump absorption. Tall claims for any rear end to accomplish at the same time.

It took some time to readjust my riding style, fear of pedal strikes and years of jumping over and pumping through nasty terrain are hard to unlearn. But I forced myself to pedal through some gnar and was surprised to gain speed.
The rear end did its job incredibly well. I could feel the back end sucking up the hits and the bike scooting forward.

Through the rough stuff and through the bends, the frame’s stiffness was felt, it held a line very well and didn’t get out of shape when landing crooked. The updated geometry paired with a wide bar and stubby stem felt as a modern 160mm sled should feel, roomy, confident and controlled.
Ellsworth Rogue Sixty vs. the competition
A mere paragraph won’t do justice here, the Rogue Sixty is in what could be argued the most competitive product class in mountain biking. With that noted, I was impressed with the ride and the acceleration, and could feel its enduro racing ability.
