The Synapse LAB71 is the range-topping version of Cannondale's World Tour endurance road bike, blending race-level performance with real-world comfort and handling. The Synapse was named BikeRadar Bike of the Year 2025 for its balance of comfort, handling, fit, features and value, and this is the ultimate expression of it.
The LAB71 Hi-MOD carbon frame weighs under 1,000g, has a stunning finish and clears tyres up to 42mm. It's built with a top-level professional spec: SRAM RED AXS 13-speed with an integrated power meter, Reserve 42|49 carbon rims on DT Swiss 180 hubs, a CeramicSpeed bottom bracket and Cannondale's one-piece SystemBar R-One carbon cockpit, all designed to turn every watt into speed and distance.
It comes equipped with SmartSense Gen 2, Cannondale's integrated light and radar system, with an 800-lumen headlight and Garmin Varia radar tail light running from a removable internal battery, plus a downtube StashPort with a large StashBag and a Cannondale/Garmin wheel sensor. Pedals are not included.
