We test ride Cotic\u2019s updated 140mm-travel trail bike <\/p>

Cotic\u2019s second-generation Jeht gets a range of updates, including a revised front triangle, built from UK steel in Scotland, as well as tweaks to the sizing and suspension.<\/p>\n

The Jeht is Cotic\u2019s do-it-all bike, featuring 140mm of travel<\/a> at the rear, controlled by the brand\u2019s droplink suspension, and 150mm travel at the front. The updated bike rolls on 29in wheels<\/a>.<\/p>\n

The development of the Jeht, Cotic\u2019s biggest-selling full-suspension bike, saw influences from Cotic\u2019s FlareMAX<\/a> and RocketMAX<\/a> bikes.<\/p>\n

Cotic has built the bike to be highly versatile, with nimble handling to help in tight trails and plenty of suspension and capability via the Longshot geometry to work well uphill, too.<\/p>\n

I rode the new Jeht for a day before its launch and you\u2019ll find my initial impressions later in this article.<\/p>\n

In essence, this feels like a marginal, but noticeable improvement over the previous-generation Jeht<\/a>, but I\u2019m looking forward to spending more time on the bike in due course.<\/p>\n

Joining Cotic\u2019s other droplink full-suspension bikes, the Jeht is now manufactured in the UK by frame builders Five Land Bikes, with Datatag security fitted from the factory.<\/p>\n

The new front triangle, which sees developments in the tube shapes, is constructed from Reynolds 853 steel. This frame material<\/a> is made in Birmingham, in the UK, from recycled metal. Cotic says this is about as environmentally friendly as frame production can get.<\/p>\n

Cotic publishes its sustainability statement<\/a>, while Reynolds has an impact report on its steel tube manufacturing<\/a>.<\/p>\n

In terms of frame tubes, there\u2019s a redesigned Ovalform HD down tube, built to be stiffer and stronger than the previous Jeht\u2019s, without increasing weight.<\/p>\n

There\u2019s also a new brace joining the down tube and seat tube, bolstering front-end stiffness and durability.<\/p>\n

The head tube has a standard form, with no cables routed through it. There are large Enduro MAX bearings sitting around 15mm main pivots, two bottle cage mounts, room for 2.5in tyres and a Syntace X-12 axle (non-Universal Derailleur Hanger<\/a>).<\/p>\n

The rear swingarm is shipped in from Asia, and is alloy, as per Cotic\u2019s other full-suspension bikes.<\/p>\n

Cotic uses its droplink suspension system on the Jeht to provide 140mm of travel.<\/p>\n

This is a linkage-driven single-pivot design<\/a>. The large main pivot sits behind the chainring. A rearward pivot on the seatstays and droplink connects the seatstays to the seat tube.<\/p>\n

Cotic has increased the progressivity of the suspension on this generation of the Jeht. This, it says, makes the bike more supple in its early stroke, increasing grip and comfort, before ramping up late in the stroke to give greater control on bigger hits.<\/p>\n

Progressivity is tuned depending on the bike\u2019s size, with the larger bikes and heavier riders getting more progressive suspension, ranging from 22 per cent to 28 per cent \u2013 these are relatively high figures for a trail bike<\/a>.<\/p>\n

Cotic hasn\u2019t changed anti-rise or anti-squat from the previous-generation bike \u2013 these figures relate to the impact of pedalling and braking, respectively, on the suspension.<\/p>\n

Cotic\u2019s Longshot geometry takes inspiration from Geometron\u2019s bikes.<\/p>\n

The concept is based around a short 35mm stem, with correspondingly longer reaches to give confident handling at speed that\u2019s still quick and nimble when it needs to be.<\/p>\n

Compared to the old Medium and Large sizes, the new C2, C3 and C4 bikes that fit within that older range have shorter seat tubes. This should enable riders to run longer-drop dropper posts<\/a>.<\/p>\n

The larger C3, C4 and C5 frames have a steeper seat angle than the C1 and C2, to improve fit for taller riders.<\/p>\n

Cotic has lowered the bottom bracket by 6mm compared to the previous-generation bike to improve cornering, increasing the frame\u2019s stack, but has kept the same head angle and rear centre.<\/p>\n
