Unicoi Endurance XC
Unparalleled performance, versatility and simplicity.
For those obsessed with speed, cross country riding demands are quite simple: traverse the terrain as fast as possible. The Unicoi will take you there.
Named after a trail-rich area of northeast Georgia, the Unicoi has an enviable cross country racing legacy, ridden at events ranging from the Olympics and UCI World Cup to stops to your local XC series—and it’s certainly no stranger to the podium.
The Unicoi’s proprietary Uni-Strut dual spring construction is its unique signature, delivering two bikes in one. Our 3AL/2.5V titanium construction has allowed our engineers to marry an agile titanium front triangle to brilliantly designed rear triangle with rear suspension damping. With 45mm (1 ¾ inches) of rear travel and a dual spring-controlled design that manages compression and rebound, the frame has just enough suspension to keep the rear tire firmly on the ground—and you in total control— on searing fast rocky or rootydescents. When paired with a 120 to 140mm fork, you have an XCbike that delivers the confident control of a full suspension ride. With all that capability, it’s no wonder some of the biggest brands in thebikeindustry haveadopted our design for their own XC range.
Despite that suspension capability,the Unicoi delivers the stiff performance and incredible weight savings expected in in a titanium hardtail. On climbs, the absence of a mechanical suspension helps keep theUnicoi light and nimble, with rear end stiffness for responsive punch and traction when scrambling up steep grades. A set of Litespeed carbon chainstays elegantly finishes the frame adding torsional stiffness, enhancing climbing performance.
Unicoi is versatile enough to manage speed of all types. With option to run 29” or 27.5+” wheels, pick your poison; bigger 29” wheels for all-out top-end speed, or go for the 27.5+” wheels that deliver surgical handling through even the gnarliest of rock gardens.
LiveChat with us to tailor you Unicoi into a machine with every whim addressed. We are happy to accommodate in making the bike of your dreams.

The Unicoi’s hardtail strut design helps keep the traction to the ground while climbing, flowing through singletrack and tackling descents. The simple design also saves weight when compared to full suspension models.
