Litespeed Unicoi XTR


Unicoi Endurance XC


The Unicoi provides unparalleled performance, versatility and simplicity.

Named after the trail-rich northeast region of Tennessee, the Unicoi has been ridden over the years in some of the most prominent cross country races, including the Olympics and UCI World Cup. The new Unicoi has evolved from a deep history of unmatched performance and attention to detail.

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

Litespeed's proprietary Uni-Strut dual spring system is designed to control the compression damping and reduces rapid rebound & top out, providing 45mm (1¾ in) of rear travel that is best combined with a 120mm travel fork. The Unicoi is built with Litespeed's carbon chainstays to stiffen the bike while still retaining its high performance.
