2017 S-Works Epic FSR World Cup

This World Cup version of the S-Works Epic FSR takes the concept of fast to another level. Like its counterpart "standard" version, it's constructed from our finest carbon fiber and features a drool-worthy build kit and a RockShox SID fork. But where it differs is in its tighter geometry and one-by-specific build, which work together to form explosive power transfer and an even nimbler sense of handling. Along these lines, you'll find that the build holds nothing back, delivering a SRAM XX1 Eagle 12-speed groupset that's lightweight and intuitive, along with Shimano XTR brakes for some of the best stopping power in the business. And to drive even harder on efficiency and speed, we included our proprietary Brain technology at the fork and rear shock. This intelligent system is able to interpret the difference between rider and trail input, so it stays firm under effort and plush over bumps. Put it all together, and you have a purpose-built race machine that's certain to lay waste to any short track out there.

• S-Works FACT 11m carbon fiber frame provides the ideal blend of stiffness, strength, and light weight, resulting in the pinnacle of efficiency and speed. Meanwhile, our World Cup XC 29 Geometry, 95mm of travel, internal cable routing, and a SWAT™ Tool Cradle create exceptional handling and zero-hassle maintenance.

• The RockShox SID World Cup 29 w/ Brain fork provides 100mm of efficient travel. It features Brain technology that distinguishes between terrain and rider input in order to maximize your power, while a Brain Fade adjusts the oil flow when not hitting bumps.

• The one-by drivetrain is controlled by SRAM's venerable XX1 Eagle components, while braking duties are handled by a SRAM Level Ultimate carbon lever. Combined, the system forms the ultimate in efficiency and intuitive feel, while also having the added benefit of significant weight savings and minimal required maintenance.
