2020 was a challenging year for downhill mountain biking. However, despite the small sample size of pro racing this year, the YT Tues proved yet again that it is one of the greediest bikes out there, enabling Oisin O’Callaghan and David Trummer to ride to Gold and Silver during the World Champs. World-class athletes have secured several World Championships, World Cup Overalls, and Rampage titles on this bike in years passed – a success story that started back in 2008 and truly kicked off in 2010. Celebrating its tenth anniversary since the conception of the V4L suspension linkage, YT test rider Erik Irmisch sends it on the big rig through Germany. The 32-year-old has played an essential role in the evolution to develop the Tues into the beast it is today.
Erik ‘Irm’ Irmisch has been with YT since 2010 and is closely linked to the evolution of the Tues – YT’s ruthless and uncompromising downhill rig. The downhill racer is part of the product development team and gives valuable feedback from an athlete’s perspective to the engineers and developers. In the early days, the Tues' development was spearheaded by Stefan Willared, former CTO and today CIO of the company. Both Stefan and Erik have played a vital part when it comes to the evolution of YT’s downhill bike.
This year marks the 10th anniversary of the Tues with the V4L technology – a milestone in the history of the radical downhill bike that has carried many riders to podiums, medals, and titles. The bike has come a long way since 2008. Initial development took 12 months until the first aluminum Tues was ready to be brought to market in 2009. With 180mm travel and a Marzocchi 66, it was more a freeride bike than a downhill rig.
However, the former CTO Stefan Willared was not entirely satisfied, which resulted in a seamless transition and development of the Tues MKI.
This resulted in the evolution of the Tues from a freeride bike to a true downhill bike.
But innovation did not stop here. 2011 witnessed the release of the Tues MKI with improved V4L kinematics and an increased rear shock length from 222mm to 241mm, which unlocked even more potential and speed. Boundaries were tested yet again a year later with the release of the Tues MKII, the first hydroformed aluminum frame and even longer rear shock length (267mm).
After major developments four years running, time was spent the next three years working on the next major milestone for YT’s Tues. Stepping into a new world of mountain bike manufacturing the first carbon Tues frame (MKIII) was released in 2015 along with the ‘new’ big 650B wheel size.
The latest steps in its evolution followed in 2018 and 2019. The Tues MKIII received a redefined aluminum and carbon geometry and for the first time, YT was able to offer five different frame sizes
The inception of the 29’’ wheel size for the platform in 2019 was the latest major development for the time being. The Tues has changed considerably over the past decade and a team effort of passionate designers, engineers, and racers has created a downhill mountain bike capable of carrying the world’s best athletes to World Championship and World Cup title and Rampage glory.
