YT Announces the New Jeffsy 27

Not even one month after presenting the new 2017 bike range YT is at it again, rolling out another trail bike – the JEFFSY 27.

It was only last year that YT appeared in the all-mountain market, where they made quite an impression. This segment now sees further growth with the arrival of another model: The JEFFSY 27 is the right choice for those seeking an even more agile and playful bike than the JEFFSY 29 – already one of the most fun-loving 29ers on the market. When it comes to getting aggressive, JEFFSY 27 follows in the footsteps of its big brother, too: in giving it a little bit extra travel, the developers made sure this 27.5” bike won ‘t get hung up on rough terrain. It is available with 160mm of travel on the top of the range model, and 150mm on the rest of the line-up. When it comes to suspension travel, the 160mm JEFFSY CF Pro Race is most suited for racing applications, where in addition to pedaling efficiently the bike also needs to have a tad more gravity potential. YT team rider Bryan Regnier will use JEFFSY for several Enduro World Series races this season.

"When choosing the right wheel size for you, your personal preferences, your riding style, and of course also the terrain you ride all play an important role in the decision. Everybody should decide for themselves which wheel size is most appropriate for them. At the end of the day, it’s not about numbers but about how much fun you’re having on your bike. Everything is what you make of it.”
Markus Flossmann, CEO"

Technical Data

The carbon frame weighs in at a scant 2300 grams, while its aluminum counterpart tips the scales at 2900 grams. Just like on the JEFFSY 29, a Flip Chip lets you dial in your ride: in the low position, you get an aggressive, 66-degree head angle and a significant BB drop (15mm). Those who climb a lot might prefer the high position, which yields a 75.5-degree effective seat angle. Naturally, YT’s highly acclaimed V4L suspension layout is also used on JEFFSY 27; it provides great small-bump sensitivity, good mid-stroke support and significant end-stroke progressivity. The BOOST standard was used for the rear axle spacing and the crank in order to provide more space between the chain ring, chain stays, and tire. An E-Type mount makes sure you can always install a front derailleur, even on the single chain ring models. Last but not least, the protectors on the stays help keep drive train noise to a minimum, whilst the discretely integrated alloy “chain suck guides” protect from damage caused by a fallen chain.

The Carbon Models

The JEFFSY 27 is available in four carbon versions: CF Pro Race, CF Pro, CF One, and CF Two. The top of the line JEFFSY 27 CF Pro Race features only the very best parts, which makes it an ideal choice for racers and pro riders. It is also the only bike in the range that offers 160mm of travel, ready to get rowdy. The Kashima coated FOX Factory suspension components were designed for aggressive trail riding and serious enduro racing, and they are both ready to mix it up with the best. Drivetrain wise the choice felt to e*thirteen being a very reliable and robust cassette for racing with its perfect range of gears. Carbon wheels, crank, and handlebar help keep JEFFSY’s weight really low, this rocket weighs a mere 12.4 kg. The JEFFSY 27 CF Pro is also a convincing package with extraordinary specs: The FOX Performance Elite suspension shines with top-class responsiveness on aggressive downhill sections as it comes with exact the same damping cartridge as the big brother Factory Series. In fact, the only difference between the Performance Elite fork and the Factory Series are the hard-anodized stanchions. Another eye-catcher on the CF Pro: the SRAM Eagle transmission which with its twelve gears makes the front derailleur superfluous. Those who prefer RockShox suspension will find themselves in great company with the JEFFSY 27 CF One or CF Two. The CF One offers a crisp, 11-speed SRAM transmission while the CF Two provides 2x11 gears via Shimano’s XT group.

The Aluminum Models

When it comes to aluminum, YT offers a choice between the JEFFSY 27 AL One and AL Two. Neither have anything to envy their carbon colleagues, since they are both based on the same frame platform. The user-friendly suspension components are easy to set up and adjust, even for beginners. Both bikes offer 150mm of ready-to-rumble suspension travel front and rear: A RockShox Pike RC fork and Deluxe RT shock on the AL One, and a RockShox Pike RC and Deluxe R on the AL Two. The biggest difference between the two aluminum models is the drivetrain: the AL One features a SRAM X1 1x11 transmission while the AL Two goes 2x11 with SRAM GX.

All models come in S, M, L, and XL sizes and are available to order as of today on the website www.yt-industries.com. At the end of April YT’s Rolling Circus will once again head out with all the different JEFFSY models on a huge test tour of Europe’s trail centers and bike parks. The exact dates and places will be published in March.

JEFFSY 27 or JEFFSY 29: it doesn’t matter which wheel size you believe in, it’s what you do with it that counts. Size doesn’t matter. Ace Hayden and Bryan Regnier checked it out lately in Squamish. Now online on YouTube. Size doesn't matter – it’s what you do with it.

YT Presents Their 2017 Range

YT is proud to present its 2017 bike range – the new models are available on yt- industries.com as of today. Brand new specs, rich new graphics and new sizes are among the highlights.

For this year, the JEFFSY, CAPRA, and TUES will all be available in the very exclusive CF Pro Race version. Thanks to the new flagship “Liquid Metal” paintjob these high-end bikes will certainly turn some heads on the trail, while the killer builds and highly adjustable components will be high on every racer’s or pro-rider’s wish list.

Another highlight of the new range is the introduction of an XL size for both the CAPRA CF and the TUES CF – welcome news for any rider who enjoys a bike with longer reach. In general, the new range offers everything that YT has built its name on: from entry-level race rigs for Young Talents to the most exclusive premium builds, there is something here for every budget and every riding style.

 

JEFFSY

When it was released in 2016, JEFFSY dropped like a bomb. 2017 promises more of the same: YT’s aggressive 29er trail bike will for this year also be available in a CF Pro Race version, sporting a rad new paint job and the very finest components. With Kashima coated FOX Factory suspension, SRAM Guide Ultimate brakes, Renthal carbon handlebars, a carbon crank and wide range cassette from e*thirteen, this exclusive bike inspires maximum performance – and not only on the race track. Meanwhile, the JEFFSY CF Pro confidently holds its own line, with FOX suspension that casually smooths out the most uneven of trail surfaces. For those looking for a wider selection of gears, the JEFFSY CF Two and AL Two with their SRAM 2x drivetrains have plenty in reserve. And last but not least, the AL One is a perfect entry-level machine that scores extra bonus points thanks to reliable components and an unbeatable price.

Capra

The carbon version of this enduro legend is available with three different builds for 2017: CF Pro Race, CF Pro, and CF. The CF Pro Race is the flagship offering of the enduro range, once again ready to go into battle sporting Kashima coated FOX Factory suspension components. All new for 2017 are the e*thirteen carbon wheels on the CF Pro Race, as well as the Race Face and e*thirteen dropper posts that appear for the first time on the CF Pro and CF models. Those who prefer aluminum will find what they seek with the AL Comp or the AL. Both aluminum models come equipped with RockShox suspension components: the highly acclaimed Lyrik fork pairs up nicely with the Monarch+ RC3 and Monarch+ R, respectively. For ultimate shifting performance, all CAPRA models run SRAM 1x11 drivetrains this year.

YT Tues

Aaron Gwin successfully proved last year that the TUES is not only a World Cup worthy downhill bike, but that it has the pedigree to claim the top spot of the podium. Reason enough for us to build a CF Pro Race version! FOX’s 40 Float Factory fork and Float X2 Factory shock deliver World Cup vibes in the suspension department. Freshly introduced to the downhill game by Gwin himself, the TRP Quadiem G-Spec brakes are on stopper duty for the first time this year. Carbon wheels and cranks from e*thirteen and the carbon handlebar from Renthal help keep the weight down and the reliability high – just as you would expect on a purebred race machine.

At YT, it’s not only the flagship model that belongs on the racetrack. The TUES CF Pro and TUES CF were also born to compete: the CF Pro with its noble FOX suspension, or the CF with its easy-to-tune RockShox BoXXer Team and Vivid RC2 shock. Finally, the TUES AL is a fun and affordable way to get into the sport of downhill – offering outstanding components for smaller budgets.

YT Jeffsy Announced

With JEFFSY, the guys and gals out of Forchheim attack the Trail Bike category and get rid of prejudices regarding 29ers. YT’s latest bike is definitely the most gravity-capable Trail Bike on the market: a downhill-ready geometry, a voluminous but light frame and a compact silhouette with superb specs.

CTO Stefan Willared and his team put in the work of three years to develop JEFFSY. When they started the design for a new bike, it was not their goal to develop a 29er. Their main questions were: What does the perfect Trail Bike even look like? And what is Trail Biking, the YT way? At the beginning, nobody would have thought that they would come up with a 29” bike but they were open to all sorts of different concepts. The guys had one mission on their schedules: Developing a true trail-rocket which is comfortable and smooth to ride on, ready for you to shred hard and still has looks to kill for.
After countless tests and variations, they quickly realized that the larger wheels definitely fit in brilliantly with YT’s gravity genes. However, what does this actually mean?

The Virtual 4 Link suspension technology, which has already proven itself on the TUES and CAPRA is also equipped on JEFFSY’s rear end. The frame has a downhill-capable geometry and JEFFSY already had observers doubting if they are actually looking at a 29er.

The 66,8° head tube angle is one of the most aggressive ones of the Trail Bike category. The low bottom bracket lets you sit directly in the sweet spot of the bike. With the equipped Flip Chip technology, the rider has the option to either ride JEFFSY in a high or low position, the latter responsible for a bigger BB drop and a more aggressive head tube angle. The low stand over height, the wide riser handlebar and the compact chain stays ensure optimal and completely atypical handling for a 29er. YT doesn’t accept any compromises; therefore, the length of the rear triangle is optimized for each frame size. Sounds like JEFFSY is the perfect all-round bike out there.

JEFFSY’s voluminous but light full carbon frame and its compact silhouette already have some observers doubting whether they are actually looking at a 29er. With its aggressive headtube angle, low standover height and compact chainstays JEFFSY is a player among trail bikes, ready to go fast and get loose in the roughest of terrain. The length of the rear triangle comes optimized for each frame size and ensures a completely new and atypical handling for a 29er.

Thanks to the flip chip technology, JEFFSY’s geometry can be perfectly adapted to different terrain and to your style of riding. The low position gives you a more aggressive headtube angle and a bigger BB drop – perfect for quick and grimey downhill sections. The high position provides a smaller BB drop, so you can blast trails and tight turns with more ground clearance. Our prized Virtual 4 Link suspension technology is present on JEFFSY as well; sensitive, progressive, 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. The tube walls are thicker in critical areas to make sure the frame can handle the abuse, and integrated protectors keep the downtube and chainstays out of harm’s way when the action heats up.

YT Jeffsy CF Pro Spec's

The standout highlights of our top of the line model are the DT Swiss carbon wheels and the FOX suspension components consisting of the FOX Float DPS Factory shock and the FOX 34 Float Factory fork. The 780mm wide carbon handlebar and carbon cranks complete this high end build. With SRAM’s X01 transmission you shift precisely, easily, and silently, and should things get a little hectic, the Guide Ultimate brakes slow you down with authority. The JEFFSY CF Pro is the no-holds-barred bike for riders who accept no compromises.

YT Jeffsy Geometry

JEFFSY CF Comp 1

YT’s gravity background runs deep in the specs of the JEFFSY CF Comp 1:  RockShox’ PIKE RCT3 fork and Monarch RC3 shock are ready to smoothly take on any root nest or rock garden. The wide RaceFace cockpit provides a maximum of control on wild descents and SRAM’s Guide RSC brakes provide ultimate stopping power. The 1x11 drivetrain calmly shifts into next gear.

JEFFSY CF Comp 2

With the JEFFSY CF Comp 2, YT offers a Trail Bike with prime specs. The 2x11 drivetrain allows a wider range of gears to shift through, so there are no excuses for the next uphill section. This carbon bike comes equipped with an entire Shimano XT group that is snappy and reliable, as well as a wide RaceFace cockpit, a RockShox Reverb Stealth, and sturdy 2.4” Onza Ibex tires.

JEFFSY AL Comp 1

The aluminum version, JEFFSY AL Comp 1 also gets a full load of dependable parts. RockShox’ Pike RCT3 and Monarch RT3 get riders through gnarly sections with ease and have your back for racing as well. SRAM’S GX 1x11 drivetrain ensures smooth shifting and the Guide RS brakes slow any rider down when things get out of hand. The 2.4” wide tires by Onza not only look good, but also deliver when it is time to send it through the rough stuff. At 13.5 kg the JEFFSY AL is a weapon for any trail and there are still some bucks left for the next bike trip.

JEFFSY AL Comp 2

For anybody looking for a wider range of gears, the AL Comp 2 with its 2x11 drivetrain is the right choice. The RockShox Pike RCT3 and Monarch RT3 keep things smooth even in the roughest terrain. When it comes to shifting gears and braking, Shimano’s XT group ensures precise shifting, optimal chain line and excellent reliability. Onza’s 2.4” tires are puncture resistant and offer great traction. Naturally, the RockShox Reverb Stealth is part of the stock JEFFSY AL Comp 2 build.

JEFFSY AL

The JEFFSY AL is the entry level trail bike available for a killer price: Even with this model, riders can expect top quality specs: Armed with the RockShox Pike RC and Monarch R the bike is ready for the next adventure. A 2x10 drivetrain has a full range of gears to choose from and Shimano’s SLX brakes bring you to a safe stop when needed. The stock build also includes a RockShox Reverb Stealth, a wide RaceFace cockpit, and tough, reliable Onza Ibex tires.

JEFFSY is the perfect choice for long trips through the woods, alpine and blocked terrain and rough descents. 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 diameters- uphill as well as downhill.
Hence, JEFFSY is born to rule any trail and offers a whole lot of gravity potential for riders to get wild and rowdy.

Whether you prefer to go wild on a carbon or an aluminum bike is something we leave completely up to you. The aluminum JEFFSY is no less remarkable than its carbon buddy, because both versions are based on the same platform. However, aluminum is a less expensive material, so it offers all the bangs for less bucks compared to the carbon bike. Reliability and a lower starting price are factors that speak for our well-equipped aluminum models.

Of course we have also achieved high levels of stiffness and reliability during the development of our carbon frames. Using a monocoque production technique, the tube walls have been given extra thickness where required to stand up to the strong forces generated in critical areas. The carbon frames weigh significantly less than their aluminum counterparts, and form the basis for our PRO models, which also feature the finest components.
