Key Performance Factors


Wide 25mm inner rim width is optimized for 40-50mm gravel tires and can fit XC mountain bike tires up to 2.3”. This wider design provides maximum sidewall support for better cornering performance, and allows riders to run lower tire pressure for reduced rolling resistance and increased compliance and traction. Compliance is further enhanced thanks to shallow weight-saving 25.8mm rim depth.


Hookless rim walls with straight, reinforced bead improve carbon structure consistency, helping disperse impact load and boost durability. Precision engineered reinforcements around each spoke hole provide added support precisely where it’s needed without adding unnecessary material.


Optimized carbon layup creates an exceptionally robust and stiff rim structure that shaves weight and enhances transmission efficiency. Dynamic Balanced Lacing technology and cutting-edge Giant instant engagement 60-tooth ratchet freehub provide immediate and efficient power transfer.
