Jeffsy Core 2 AL

The JEFFSY CORE 2 AL packs our gravity genes into a stout, 150/145mm package, and is ready to be your go-to choice for any MTB adventure. From technical singletrack to high-speed flow trails, this bike rips, and its spec reflects that. We've gone big in all the right areas with FOX suspension, DT Swiss wheels, and Hayes Dominion brakes, while the high-quality aluminum frame balances performance and durability, ensuring this ride is always ready to throw down.

It's your call. We offer the JEFFSY CORE 2 in aluminum or high-modulus carbon fiber, so you'll always get the frame you want – choose carbon for a performance edge or aluminum for that FULL METAL feeling.
