While 2016 brings updated aesthetics to the Ellsworth Epiphany 27. 5 Mountain Bike Frame, you can rest assured that it features the same suspension and geometry found in its much loved predecessor. The California based brand perfected its ideal suspension clear back in 1991, and has been ripping trails with its Instant Center Tracking ICT technology ever since. Ellsworth claims that the Epiphany's ICT suspension is the most advanced suspension platform in the world. As it moves through travel, ICT keeps the instant center or virtual pivot created by ICT's four bar suspension as close to the chain force line as possible. In on trail terms, it maintains a steady pedaling platform so your power is always transferring into forward motion instead of dissipating into unnecessary vertical sway. Furthermore, ICT doesn't require a lock out, so you can keep the FOX Float DPS shock's travel fully active, even while climbing. The addition of chain torque doesn't constrain the system's travel, the Achilles heel of so many otherwise efficient suspension designs, so pedaling and bump compliance aren't working against each other. The end result of ICT is a plush, less fatiguing ride with greater control and responsiveness over all terrain. Previous models of the Epiphany were available as XC or enduro models, with the difference being a few degrees of head tube angle. When paired with a 150mm fork, the current generation's 27. 5in carbon model splits the difference at 69. 5 degrees, which primes it for reckless abandon across moderately rocky trails without sacrificing nimble agility on climbs and while dicing lines across gnarlier terrain. The Carbon Torsion Arch connecting the CNC machined aluminum rockers and chainstays complements the Boost rear axle for an even stiffer rear triangle, and the single 12mm bolt needed for each pivot assemblage makes for a lighter, less complicated system.
