The all-new Cotic Jeht (pronounced Jet) is the latest addition to Cotic’s steel full suspension mountain bike collection. The third 29er to grace the roster, the Jeht sits between the 132mm travel FlareMAX and the big-hitting Gen3 RocketMAX enduro bike.

Cy, founder of Cotic, describes the Jeht as more capable than the FlareMAX but “more of an all-rounder, a bike that’s easier to move around than the RocketMAX”. That’s its positioning; before we get into the all-important geometry and kinematics, check out this one-of-a-kind shreddit from the the Lake District’s Honister Slate Mine.

Cotic Jeht 29er trail bike

The all-new Cotic Jeht is a 140mm travel 29er trail bike with some very-capable looking geometry figures. A true Cotic, this new full suspension mountain bike is fabricated from Reynolds 853 steel tubing and features their proprietary ovalform top tube for added ride compliance.

That 140mm rear wheel travel is paired with a 150mm travel fork. The Jeht uses a new long link droplink kinematic which Cy says keeps the progression curve more consistent through it’s travel.

It also has the benefit of allowing for 15 – 20mm extra seat post insertion, meaning all riders should be able to run a minimum 150mm travel dropper seat post regardless of frame size (if they use a OneUp dropper).

The new kinematic has also changed the way Cotic set up the base tune on the Cane Creek and Rockshox shocks. The Jeht runs 2 volume spacers said to produce a lively and feedback-rich feel to the suspension. For riders looking for a little more comfort there is the option to drop a spacer out. To heavier riders, Cotic recommend dropping a spacer to combat the extra ramp up that higher pressures bring to the spring curve.

LongShot Geometry

The Cotic Jeht conforms to their LongShot geometry principles, built around a short 35mm stem for nimble handling. Out front, that 150mm fork sits at a head angle of 64.5°. That steepens to 65° if you opt to run a shorter 140mm fork for a sharper ride feel.cotic jeht afterburner frame color longshot geometry long reach trail bike mtb

Cotic have optimised the Jeht’s seat tube arrangement such that the rider’s chosen saddle height doesn’t have a huge influence over the angle relative to the bottom bracket. The seat angle sits at 75.8° at 720mm saddle height, and 75.5° at 815mm saddle height.

Reach is fairly generous, spanning a 444mm to 515mm range across the small to XL frame sizes. The chainstays are long at 447mm and consistent across the size range, with the BB dropping 27mm. 

Cotic purposely keep seat tube lengths shortish (425mm in medium) to allow riders to tailor their frame size to their local trails, rather than the standover height.
