Specialized Epic WC Expert – The fastest full-suspension XC in its category
The Specialized Epic World Cup Expert represents the new frontier of XC racing: a bike designed to be faster, lighter, and more precise on every smooth trail. Its unique combination of hardtail efficiency and full suspension control creates an unmatched riding feel, as confirmed by champion Christopher:
"This bike gives me everything I want from a hardtail, with the added control and capabilities of a full suspension."
The result comes from a fully integrated development process and the experience of four decades of off-road victories.
NEXT-GENERATION FRAME – Stiff, precise, extremely fast
To achieve the best possible power transfer efficiency and unprecedented riding precision, Specialized engineers have redefined industry standards.
The Epic WC frame is the most sophisticated ever made by the brand, with a double diamond design and an integrated shock absorber as a structural element. The result is an extremely stiff, responsive frame designed to achieve maximum speed.
FAST SUSPENSIONS – The efficiency of a hardtail, the control of a full suspension
The rear suspension has been completely reinvented. The new RockShox SID Deluxe WCID (World Cup Integrated Design) uses independently adjustable positive and negative air chambers, offering:
the typical responsiveness of hardtails
the capacity and stability of a full suspension
the ability to adapt the setup based on the route or riding style
The 75 mm of rear travel feels like more, thanks to optimized air volumes and damping. Added to this is a dedicated MegaJounce bumper, perfect for handling the hardest impacts without sacrificing control.
BRAIN – The smart technology that thinks for you
The RockShox SID SL fork integrates the innovative BRAIN technology with position sensitivity and 15 mm of sag. No manual levers or lockouts needed:
the system automatically knows when to stiffen and when to absorb, adapting to the terrain in real time.
ABSOLUTE LIGHTNESS – The lightest frame in the category
With only 1765 grams (painted, with shock), the Epic World Cup Expert is the lightest full XC on the market.
Lightness translates into:
The carbon layup leverages knowledge gained from developing the renowned Specialized Aethos, pushing stiffness/lightness to the highest level.

A Complete Guide to Bike Sizes
Foreword: Not all bike sizes are the same
Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.
Bicycle adjustment margins
Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.
How to use size charts
We've created a simple guide to help you find the right bike size:
- Check out our size charts for each bike type.
