YT Industries' downhill bike, the Tues, has been around for years now in its current guise, and with its sponsored athletes riding a covered-up frame, it comes as no surprise that the brand has been working hard behind the scenes on a new and improved version – the Tues MK4.

The Tues is a bike that's made its name on the downhill scene with the likes of Cam Zink riding it at the Red Bull Rampage several times and Vali Holl winning two World Championships and World Cup titles, just to highlight a sliver of the bike's prestige.

Now in its fourth iteration, the Tues features two main changes with the first being its geometry. The new model fits into the YT Industries current sizing concept and the reach figure stretches by 20mm from size to size, with the S frame getting a 430mm measurement and the XXL benefitting from a 510mm reach.

The bike then benefits from a 63.5-degree head tube angle, a 76.5-degree seat tube angle (on a large), and a 1,267mm wheelbase. However, within those figures is a whole host of adjustment opportunities.

First off, YT has kitted the Tues with a Flip Link, that allows the rider to ride either a mullet or full 29-inch wheel on every frame size. That head angle can then be slackened by a further 0.3 of a degree and there's another flip chip at the lower shock mount that allows for 5mm of bottom bracket height adjustment.

The chainstays are size specific but there's some adjustment there too as the Tues provides 5mm of adjustment. That's on top of the chainstay length changes that come as a result of changing the rear wheel size.

As for suspension, there's 200mm at both ends with the rear travel being delivered by YT's V4L linkage that's been designed to help gather speed while carrying the progression needed for big hits. The bike's been made to be friendlier to the mechanics too, coming equipped with replaceable shock hardware inserts, there's now a threaded bottom bracket, and the Tues is sorted with an EC49/ZS56 headtube that allows the frame to run reach adjustment headsets.

YT Industries is offering the Tues MK4 in two builds, the Core 4 and Core 2. The Core 4 gets a Fox Factory 40 fork and a Fox DHX2 coil shock for all of the suspension adjustments. Slowing the bike is a pair of TRP DH-R EVO brakes with 220mm rotors and there's SRAM's X01 DH groupset. The Crankbrothers Synthesis DH alloy rims are laced to Industry Nine 1/1 hubs and they're wrapped with a pair of Maxxis Assegai DH tyres with the mega sticky MaxxGrip compound.

The Tues MK4 Core 2 comes with a more budget-friendly build featuring RockShox's Boxxer Base fork paired with the Super Deluxe Select coil shock. Driving the bike is SRAM's GX DH groupset and braking duties are taken care of thanks to a pair of SRAM DB8 brakes with 220mm rotors. This build rolls on a set of SunRingle Duroc SD37 wheels with the same rubber as the top-tier rig.

Prices start at £4,000 for the Tues Core 2 and go up to £6,000 for the Core 4. Claimed weights are 17.2kg and 16.7kg respectively with a full 29-inch wheel setup.
