YT Jeffsy Core 2 29in Alloy Black Magic MTB

Carve through berms, rally lung-burning climbs, and tear through tech. This is JEFFSY CORE 2, a progressive full-metal ripper that holds nothing back on the trail. A premium aluminum frame, rock-solid components, and FOX performance suspension mean no trail is out of reach; with JEFFSY as your partner, your potential is unmatched. Four-piston SRAM Code brakes highlight the capability of this mid-travel rig, and to keep you out of the workshop, the durable SRAM GX drivetrain and DT-Swiss wheels shake off the heaviest hits to keep you rolling, session after session.

Three Frames To Choose
Depending on your weapon of choice, your JEFFSY will feature either a carbon or hand-crafted aluminum frameset. Our carbon fiber frames come in two options: High Modulus and Ultra Modulus. Both materials are equally durable and built for rowdy riding, with Ultra Modulus being the lighter choice.

Top Tube Rivets
Tools, check. Spare tube? Check. Why let a mechanical end your ride; use the toptube mounts to ditch the backpack to store your essentials.

Internal Cable Routing
For optimal protection and sleek lines, cables are routed almost entirely through the frame. This bike is a mechanic's dream: Uninterrupted internal tubes provide easy, intuitive cable replacement and eliminate noise for stealthy slap free riding.

Flip chip
Situated at the lower shock mount, the Flip Chip makes it quick and easy to adjust the geometry according to your ride style. This chip is set to low by default but increases the BB height by 8mm and ST/HT angle by 0.6 degrees in the high position. It's your call: Choose high for enhanced agility, precision, and climbing efficiency or low for trail-ripping confidence and a lower center of gravity.

Frame Protection
Extensive chainstay and seatstay protection guards the frame from chain slap, while the knobs reduce chain slap noise. All you’ll hear is the adrenaline rushing through your veins and your tires rolling over the trail.
