No matter your MTB goals, JEFFSY Core 1 is the answer. This progressive package is a capable all-rounder for the new breed of trail rider, ready to push your abilities as you explore your potential as a team. Even at CORE 1 level, we set the standard high: This bike features a handcrafted aluminum frame, quality RockShox suspension, and high-end tires and finishing kit. Right down to the finest details, this bike packs a punch; it's a giant killer and proof that you don't need to spend big bucks to get your fill of Good Times.
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.
