Whereas it appears to be like fairly related on the surface, this new YT Jeffsy’s third era transforms fairly a bit the deeper you take a look at it. Jeffsy has at all times been YT’s action-packed happy-medium bike – in between their shorter- and longer-travel mountain bikes. However now they absolutely embrace versatility with a brand new Jeffsy mk3 that dials-in that candy spot of mid-travel suspension, with refined geometry that’s now extra assured going uphill or down.
2023 YT Jeffsy mk3 mid-travel path mountain bike
Once more, it’s a brand new bike that goals to be the mountain biker’s greatest buddy.
Shifting a bit in how YT discuss it, what was as soon as an all-mountain bike is now a path bike. However actually, that’s much less to say about Jeffsy itself, and extra about how we trip trails now. And the way succesful trendy mountain bikes may be. With extra mountain bikers using extra technical trails, path bikes have stepped as much as the problem.
The brand new Jeffsy is a bit smaller of a motorbike general, but it surely actually does really feel extra succesful than ever on this newest iteration. Fast native singletrack laps. All day path rides. Even the occasional journey to the bikepark. There’s not lots this new path bike can’t do.
I bought the prospect to spend a couple of days using the brand new Jeffsy on moist English & Welsh trails a couple of weeks again. So keep tuned for a First Rides Evaluate coming quickly. Within the meantime, let’s dive into the main points…
So, what’s new?
Massive wheels, however much less journey!
The brand new 2023 YT Jeffsy mk3 simplifies issues by going 29er-only on this new era. On the identical time, it additionally dials it again a bit to 145mm of rear wheel journey. Vs. 150mm on the mk2 29er and even 160 on mk2 27.5″ bikes. And the brand new bikes pair with 150mm journey forks. That actually drops it extra in a logical center floor between YT’s 130mm Izzo and their 170mm journey Capra enduro bikes.
However whereas journey is barely diminished, YT refined the V4L four-bar suspension kinematics. Newly improved help on the bike’s deep 30% sag setting improves pedaling effectivity on the flats and climbs – with out making the bike harsh over small bumps. Then, later within the journey, elevated finish stroke development nonetheless means a extra bottomless, supportive really feel – even with that 5mm much less journey on the rear wheel.
The brand new Jeffsy is definitely extra succesful as ever, retaining its gravity bike inspiration mixed with newly optimized acceleration.
Modern path geometry
The geometry of the gen3 Jeffsy can also be refined to enrich that suspension tweak. A level slacker head angle and 5mm longer body Attain accompany the marginally shorter journey & snappier trip. Whereas the steep seat angle, body Stack, BB drop & size-specific chainstay lengths all successfully stay unchanged for a well-recognized trip.
There’s additionally nonetheless the identical flip-chip on the decrease shock mount for fast & straightforward tweaks to the bike’s geometry to tailor it to your personal type of path using.
New tech options, too
The brand new Jeffsy nonetheless quietly consists of two ranges of carbon development – high-end ultra-high modulus fibers on the highest Core 5 solely, with common hi-mod for the opposite carbon specs.
However there’s additionally then an all aluminum frameset to maintain the entry-level worth level affordable. Each CF & AL characteristic the identical precise geometry, and a transfer to UDH for common drivetrain or transmission matches.
The brand new Jeffsy now provides an inner storage glovebox for these carbon bikes. It’s slightly below the ahead shock mount, however separate from the bottle cage for safety. And sure, YT sweated the main points. They developed a safe latch and double-lip seals on the lid to make certain it stays in place and water stays out. Inside, a few neoprene luggage (one up & one down) provide loads of software & spares storage, whereas maintaining the whole lot rattle-free.
Beneath that, there’s a mount for an up to date side-load cage that matches a 620ml water bottle to maintain you hydrated, or most different customary bottles, too. Then, new exterior storage mounting bosses underneath the toptube will mount trailside spares for simple entry on all bikes. And even to hold a spare layer like I did,
Tech particulars
The brand new Jeffsy retains the angular headtube and low-key graphics which are constant by the YT household. Though the bike does barely realign its lined inner cable routing with new ports alongside the facet of the headtube.
The bike once more options up to date molded body safety underneath the downtube, and wrapping round each the seatstay and chainstay. The downtube protector particularly now sits simply off the body with a foam-backed insert to maintain your trip quiet, and actually shield the carbon body from rock strikes.
