How the maker describes it
Comfort, handling, going long
The generation-specific SmartSense RL road page and CY2022 manual support Road Endurance. Measured 35 mm clearance meets the GnR All-road house rule; it does not change the manual's ASTM Condition 1 road-use limit.
Classification source: Cannondale ↗. Read October 17, 2026.
Verified tire clearance
35 mm. CY2022 manual p.8: measured 700c x 35 mm without fenders; 30 mm with fenders. Not the 2025 frame's clearance. All-road is GnR’s ≥35 mm Road Endurance house rule, not an industry standard.

Mounts and carrying
Hidden rack/fender mounts and removable fender bridge, per the SmartSense RL product page.
