Specialized Chisel Shimano – The lightest and highest performing alloy hardtail in the category
The Specialized Chisel Shimano is designed for those who demand speed, control, and race performance on every type of terrain. Thanks to D’Aluisio Smartweld technology, Epic 8-inspired kinematics, and Ride Dynamics-tuned suspension, the Chisel sets new standards in the aluminum XC category: 18.4% lighter than competing models, stiff when needed, and capable of absorbing vibrations and impacts with surprising effectiveness.
Record lightness: Speed Metal
The Chisel frame is made with D'Aluisio Smartweld technology, which allows for the lightest aluminum XC frame in its category. Each tube is hydroformed and optimized with differentiated thicknesses and profiles to ensure:
The result? A hardtail ready to race, fast uphill, stable downhill, and always balanced.
Race performance thanks to the DNA of the Epic 8
Equipped with 110 mm rear travel and a 120 mm fork, the Specialized Chisel inherits geometry and kinematics from the legendary Epic 8, the World Cup XC bike.
Thanks to suspensions tuned with Ride Dynamics, it offers superior control, consistent grip, and responsiveness even on the most challenging trails.

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.
