Mountain biking has become one of the most complicated things to figure out, and not just for the ever changing standards. There are more types of mountain bikes than there are golf clubs and choosing which type(s) for the day can be stressful. Imagine trying to have to pick one golf club to use the entire day. Since most mortals are only entitled to one… maybe two bikes and racing isn’t a priority, trail bikes have become overwhelmingly popular.
One of the more welcome trends we’ve been seeing lately is more aggressive, more capable trail bikes popping up. Or are they really all-mountain/enduro bikes? Regardless, they’re centered on all day fun on what many would consider their goto “home trail”. YT Industries, a brand synonymous with aggressive bikes having made a strong mark at such events like the Redbull Rampage, has been teasing us regarding a love or hate for JEFFSY. Well, from the looks of it, this new bike could ruin as many lives as it saves…
YT Industries’ new JEFFSY is a 140mm travel trail bike with a super slack, almost downhill’ish geometry atop the larger 29 inch wagon wheels. So what does all of this mean? What it sounds like is a bike that can bomb some of the more aggressive trails with ease, but efficient enough so that you could ride all day. In other words, this bike may be the reason you see your friends and significant other less, which means some of those people will hate JEFFSY. But, for those of us willing to take the chance, this could be a bike that fulfills most of our needs. Or, at least, the ones that have to do with riding mountain bikes.
The YT JEFFSY comes in three carbon and aluminum build options:
The flagship $5,999 CF Pro (top), comes with goodies such as SRAM’s XO1 drivetrain, DT Swiss’ carbon XMC1200 Spline wheels, Fox Float 34 Factory fork & DPS Factory rear shock, Raceface Next SL cranks and Renthal carbon Fatbar.
The $4,599 CF Comp 1 (lower right), runs SRAM’s X1 with DT Swiss M1700 Spline wheels and a Rockshox Monarch RT3 shock & Pike RCT3 fork. Bottoming out (no pun intended) the carbon lineup is the $4,399 CF Comp 2 (right) which has a similar build to the Comp 1, but with Shimano XT and a couple other small changes.
The aluminum version has the same exact platform at a more wallet friendly price. The $3,499 JEFFSY AL Comp 1 (top) sports the SRAM GX drivetrain and DT Swiss M1900 Spline wheels while the $3,299 AL Comp 2 (left) runs Shimano XT. Thier “entry level” $2,699 JEFFSY AL (right) is still a great build for the price with Shimano SLX drivetrain. Complete specs for all shown below.
One really cool tidbit that will make you love the JEFFSY even more is the Thirstmaster 3000. The carbon cage weighs only 33g and the system comes with two 0.5L (16.9oz) bottles. The cage is configured for right hand delivery and has features for cable routing and frame pump mounting.
