          See you at the bottom

          Even though Jekyll boasts a unique combo of go-fast tech that’s never been seen before, it's not a bike that talks. It’s a bike that goes.

          Where it thrives

          Steep, fast, rowdy mountains

          What it's built for

          Enduro racing, bike park sessions, high-speed mobbing

          Highlights

          • Fox Float Factory 38, 170mm / Float Factory X2 Shock
          • SRAM GX Eagle 12-speed drivetrain / Code RSC hydraulic disc brakes
          • HollowGram SAVE carbon riser bar / DownLow dropper post

          Descend into Greatness

          It’s a hell of a climber but come on. Jekyll was born for the downs. Every part of it crafted for the sweet embrace of speed, every element designed to help you wring a bit more of velocity’s nectar from those steep, chunky, high pucker lines you love.

          Best. Suspension. Ever.
          4-bar meets high pivot meets idler pulley meets size-specific kinematics. For real. If you’re not up for suspension buzzword bingo, just know that it grips, floats, and pedals like nothing else. It’s always up for getting down.

          The Gravity Cavity

          The shock tucks cleanly into the twin spar downtube, keeping the bike's center of gravity as low as possible. Wicked stability, instant line changes and one-of-a-kind looks.

          Built for You

          Well, not you specifically. But someone just like you. With our Proportional Response design, everything - from the suspension layout to the geometry, even the length of the chainstays - is completely customized by size, for performance built just for you.
