SPECIFICATION
GEOMETRY TABLE
TI-XC EVOLUTION
More progressive seat and head tube angles. The seat tube angle varies from 75 on the small frame to 76 degrees on the large frame. This keeps the saddle above the cranks more for the longer legged riders. Head tube angle is 68 degrees on a 100mm fork and drops closer to 66 on a 120mm fork. This keeps the handling nice and sharp with the latest 44mm offset XC forks and 2.4" tyres.
Stem length 40-60mm (was 80mm).
The seat tube is now straight to allow for longer drop droppers, and still 31.6mm internal dropper compatible.
The BB is slightly lower at 60mm to improve handling, but not so low as to pedal strike too easily.
The chainstay/BB still uses a machined yoke. 3 benefits - increased lateral stiffness, increased tyre/chainring clearance and shorter chainstays.
The machined 44mm headtube with external lower headset cup maintains the traditional Torus style
The seat stays still extended in front of the seat tube to increase lateral stiffness.
Single chainring only for 1x drivetrains.
Laser etched headtube and - stealthy blasted down tube logo.
BB Yoke.
