Elkat was born from the belief that a mountain bike could be created to deliver a more enjoyable experience throughout the entire ride. Designed and built in the pursuit of performance and capability across the board, the modern design of Elkat's geometry and Orion suspension platform will allow you to enjoy the climbs in a whole new way and get you even more excited to drop the saddle and confidently rip down the other side.

Orion suspension design

 

 


With Dave Weagle’s patented Orion suspension platform, and Esker’s "Slack&Steep" geometry, tied together with a striking aesthetic design, the carbon fiber Elkat chassis has it all built in. State of the art geometry and Orion kinematics deliver a balanced ride that challenges you to confidently go up, down, and sideways. Responsive small bump compliance, quick cornering, and stability at speed make for a versatile bike that can be built to suit the needs of any rider, on any terrain.

At Esker, we value performance at all price levels, which is why we use Orion suspension. The bike's performance is built into the kinematics of the frame, so all of our bikes perform at the highest level, without whiz-bang shock technologies.

Geometry explained

Bike geometry is a bunch of moving numbers. Unless you are a math wizard, it's hard to tell just what is going on with those digits. The progression of trail bikes and the advent of dropper seatposts have allowed us to create a veritable multi tool, suited to various forms of mountain biking—something we like to call Slack&Steep. Slack&Steep geometry is just that, a mathematical derivative of proper suspension performance, body placement, and handling numbers designed to give you the best possible ride throughout.
