Cannondale has upgraded the entry-level alloy Synapse AL to include SmartSense technology, an integrated light and a rear sensor system.
The brand has further optimised its cheapest endurance road bike for long-distance, multi-terrain riding with top tube mounts and an increase in stock tyre size from 28mm to 30mm.
Cannondale says the new Synapse AL has a maximum tyre clearance of 32mm, which is 3mm less than the 2022 carbon fibre Synapse.
In addition, Cannondale has upgraded the mid-range Shimano Tiagra and range-topping Shimano 105-equipped models from mechanical to hydraulic disc brakes.
Both bikes now have a Fizik Aliante Delta road bike saddle instead of Cannondale’s own model.
Mechanical disc brakes and Cannondale finishing kit remain on the cheapest Synapse AL 3.

The 2023 Synapse AL retains its fittings for a rear rack and mudguards. You can now screw in a top tube bag for bikepacking trips.
A trainer axle is available to purchase separately, enabling you to ride the Synapse AL on a turbo trainer for the first time.
Cannondale has not changed the SmartForm C2 Alloy Frame material and carbon fork combination. Therefore, we expect little weight difference from the Cannondale Synapse AL Disc Tiagra we tested in 2020.
AI on the Synapse AL

Cannondale’s SmartSense technology has trickled down from the carbon Synapse range. This includes our Bike of The Year 2022, the Cannondale Synapse Carbon LTD RLE.
A battery pack stored on the down tube powers the integrated front and rear lights. It also runs a version of the Garmin Varia radar, which alerts you to cars approaching from behind.
The battery can be removed from the bike and recharged via USB-C. Judging from Cannondale’s images, you can install a bottle cage on the down tube in place of its mount.

The 2023 Cannondale Synapse AL sees subtle adjustments to the geometry.
