Before you ask
Why isn't the full build spec listed here?
Because no two builds are the same. Parts stock changes every week, so we quote what we can actually build today, in your size.
How long does a complete build take?
It depends on parts availability. Your build sheet includes a ready-to-ride date.
Is it genuine, with warranty?
Yes. Everything we sell is genuine and comes with the manufacturer's warranty.
Can I see it before I decide?
Yes. WhatsApp us and we'll have it ready at our Viman Nagar, Bavdhan or Wakad store.
Frame details & specifications
Cannondale Synapse LAB71 Frameset (Black Marble)
The Synapse LAB71 is Cannondale's top-level endurance road frameset, built from LAB71 Hi-MOD carbon with a frame weight under 1000 grams. It combines aero tube shapes, generous tyre clearance and downtube storage for long, fast rides on real-world roads.
LAB71 Hi-MOD Carbon
A sub-1000g Hi-MOD carbon frame with wind tunnel-shaped tubes and Proportional Response Construction, so the layup and geometry are tuned for each frame size. Cannondale states the carbon layup is 20% more compliant than the previous Synapse.
Tyre Clearance
Cannondale quotes clearance for tyres with a measured width of up to 48mm front and 42mm rear, with at least 4mm of extra clearance on each side.
StashPort and SmartSense
A downtube storage port under the bottle cage holds the included StashBag for tools and spares. The frame is SmartSense compatible, with one downtube battery able to power Cannondale's lights and rear radar.
Delta Steerer and D-shaped Seatpost
The Delta Steerer fork routes cables internally from the cockpit, and the D-shaped C1 Aero 27 carbon seatpost adds aero benefit and vertical compliance.
Who Is It For?
Riders building a premium endurance road bike for long-distance rides, sportives and fast group rides, who want race-level performance with more comfort and wider tyres.
Good to Know
This is a frameset: frame, LAB71 Hi-MOD carbon fork, integrated headset (with integrated spacers), Cannondale C1 Aero 27 carbon seatpost and a large StashBag. Groupset, wheels and cockpit are not included. The frame takes flat mount disc brakes, 12mm thru-axles, UDH-compatible derailleurs and has fender mounts. A proper bike fit is recommended — our team can help.
