I HATE JEFFSY
THE NEXT LEVEL When it comes to the world of gravity mountain biking we have definitely put our skills to the test and left a mark that nobody can ignore. The TUES, CAPRA and DIRT LOVE have stirred up the gravity-scene and convinced mountain bikers from all around the world. I LIKE IT WHAT IS IT? CTO Stefan Willared and his team put in three years of work to develop JEFFSY. Their mission: Building a trail-rocket which is comfortable and smooth to ride on, lightweight, ready to shred and still has looks to kill for. Our philosophy: A YT is always the most aggressive bike on the market. A YT pushes the limits. With this principle in mind, we now attack the all-mountain sector. And shake up every prejudice about it. Not shy to try out various concepts and ideas, they came back with an unexpected result: Not even we were able to deny the potential benefits of 29ers, even if this meant we had to break with old conventions to provide the basis for a YT trail bike. We couldn t predict that the characteristics of the larger wheel size would mix brilliantly with YT s It was not even our intention to develop a 29er but the questions we asked ourselves were: what do we see when we think about the perfect trailbike? What is all-mountain riding, and how do we still gravity genes. The outcome is crystal clear and only one explanation really puts the nail in the coffin: no other wheel size puts you in the sweet spot of the bike so well. keep it the YT way? We envisioned a bike which helps you reach the most remote places, a bike which gets up the mountain smoothly, that is playful and agile, a bike that is unique, fast and sexy - and a beast when it is time to go downhill. With JEFFSY we have met our high standards. Whether you re enjoying your local trail, surfin on single trails, moshin through alpine terrain or owning an enduro race - JEFFSY won t leave you hanging.
29 THE YT WAY Being a YT, JEFFSY s mission is to be the most gravity-ready bike of the entire all-mountain segment. Therefore, we equipped it up with our award-winning Virtual 4 Link suspension technology and hooked the frame up with a downhill-like geometry: Thanks to the flip chip, JEFFSY can be set-up in either a high or low position, with the latter being responsible for a sweet BB drop and surely one of the most aggressive headtube angles to be found in any all-mountain bike today. The low standover height, the wide riser handlebar and the compact chainstays ensure an optimal and completely atypical handling for a 29er. At YT we don t accept any compromises, therefore e the length of the rear triangle comes optimized for each frame size. TWENTY WHAT? Alright, it s time to get real: On a conventional 29er one looks like an ape riding an ostrich. Therefore, our designers were on a very personal mission, making the JEFFSY a subtly proportioned masterpiece. JEFFSY s voluminous but light frame and its compact silhouette already have some observers doubting whether they are actually looking at a 29er.
I AM JEFFSY FAR OUT OR NOTHING. Hometrail or alpinecross, it simply does not matter: JEFFSY s unbelievable traction and efficiency are going to get you up the steepest climbs. Uphill or downhill: JEFFSY is there to push you to the next level. DON T PUSH BOUNDARIES, DESTROY THEM. When it s time to go downhill you will feel as if riding an enduro bike. Hard banging in rough terrain, over nasty roots and rock gardens don t even sweat it because JEFFSY has got your back. It s got plenty of gravity potential and travel reserves. Just as you would expect it from a YT. HERE ONE SECOND. BOOM! GONE THE NEXT Because of JEFFSY s gravity-inspired geometry it does not lack any maneuverability and playfulness, even though that s what you would expect from a 29er. Thanks to the flip chip technology, the headtube angle and BB drop can be perfectly adapted to your style of riding. WITH JEFFSY I DRAW MORE ATTENTION THAN WITH MY GIRLFRIEND. JEFFSY is definitely a 10! The slick design gives its proportion one hell of an awesome and compact look. Looks like you and JEFFSY are going to turn quite some heads together. JEFFSY HAS MY BACK. The wide cockpit provides maximum control, the 29 wheels and the super-balanced geometry of the frame give you an absolute central position on the bike, so even the harshest sections will let you feel right at home on JEFFSY.
WITH JEFFSY I DRAW MORE ATTENTION THAN WITH MY GIRLFRIEND. JEFFSY is officially decked out. Our designers didn t rest until they came up with proportions that are completely unheard of for a 29er. The ridiculously beautiful, generously dimensioned frame and the compact silhouette result in a prime proportioned bike, that shouldn t even be in the same category with its gawky-looking fellows. JEFFSY is ready to be your new bro and wingman. You re going to be the new dream team. HERE ONE SECOND. BOOM! GONE THE NEXT In terms of agility and playfulness JEFFSY is the boss of all bosses. During its development we have placed great emphasis on a balanced geometry and optimal weight distribution. The larger radius of the 29 wheels results in a bigger BB drop which allows you to sit centrally in the bike where even the gnarliest sections won t be much of a bother. JEFFSY s low standover height lets you get away with the most wicked maneuvers, and we customize the rear end for each frame size to make sure riders of every size enjoy that perfect weight distribution. OVERCOME ALL OBSTACLES. Our award-winning Virtual Four Link technology has absolutely proven itself on our gravity bikes and now for the first time ever, it will be working its magic on a trailbike. It combines an extremely sensitive response with lots of mid-travel support: this does not only give you the confidence needed for big gaps and rugged terrain but also makes pedaling a lot more efficient.
JEFFSY HAS MY BACK. Safety insipires: Once again we gave JEFFSY some enduro genes, by choosing a wide cockpit so you have all the control and confidence you need to really let lose. Whatever happens out there, JEFFSY has your six. DON T PUSH BOUNDARIES, DESTROY THEM. The combination of an extreme slack 66.9 headtube angle, 140 millimeter of travel and 29 wheels makes JEFFSY the YT among all-mountain bikes. JEFFSY is the perfect buddy for anybody who wants to ride a tad faster, be more aggressive and more creative than the mainstream. JEFFSY IS FULL OF SURPRISES. The flip chip lets you precisely adapt JEFFSY s geometry to different terrains and to your style of riding. The low position gives you a more aggressive headtube angle and a larger BB drop perfect for quick and grimey downhill sections. The high position provides a smaller BB drop, so you can blast trails and tight berms with more ground clearance. FAR OUT OR NOTHING. The 29 wheels and their immense drive let you conquer the steepest mountains with ease. Obstacles are a piece of cake due to the larger wheel diameter uphill as well as downhill. And for the cherry on the cake: the Pro version comes swinging with carbon rims: You and JEFFSY are going to discover rad places, that are going to make you weep for joy.
