Orion Dynamics suspension design by the famed Dave Weagle.
At Esker Cycles, we design and build mountain bikes for the entire mountain so you can simply jump aboard, and you will always be ready for the ride ahead no matter where it may take you. Rowl is the pinnacle of this design principle as it can take you deep into the rough stuff and roll incredibly fast to get you even farther out there than ever before.
Modern geometry and state of the art Orion Suspension kinematics deliver a balanced ride that allows for speed and stability throughout the entire ride in every different type of terrain. Responsive small bump compliance with quick cornering and stability at speed - Rowl is an incredibly efficient and nimble bike that suits the needs of any rider on any terrain.
Esker Cycles - Built for the Back Country
We here at Esker enjoy long rides into the wild spaces and are proud to say our bikes are truly Built for the Backcountry. That means they are designed and built on three tenets:
Durability
Our carbon layup is designed to provide maximum strength in those key areas that really need it while staying light enough to keep overall weight down and give it the dampened and silky smooth feel that carbon fiber is known for. We intentionally design, engineer, and test our carbon frames higher than industry standards, because we want a frame that truly lasts.
Refined Geometry
Our “slack and steep” geometry is a design approach based on years of research and experience fine tuning the perfect balance of rider weight positioning, power transfer, and stable handling at all speeds. Some call it "progressive", but we call it "just right" after years of ride experience.
Ride Quality
The Orion Dynamics suspension keeps things planted and stable while maintaining an incredibly lively, active, and nimble feel on the trail. From breaking bumps to bottom outs, it takes the harshness out of the ride and makes the bike disappear beneath you so you can focus on the trail ahead.

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.
