Cannondale Synapse Carbon 4 Chalk
Product information "Synapse Carbon 4 Chalk"
Wireless technology paired with all-road robustness. The Cannondale Synapse Carbon 4 is equipped with the Shimano 105 Di2 and impresses with Pro Tour shifting performance without breaking the bank. The full carbon frame impresses with the familiar Synapse riding experience – quiet, fast, particularly comfortable – and also cuts a fine figure on long-distance rides with wide tyres and mudguards. Let's call it the golden mean between a rapid Sunday ride and everyday suitability.
Features - Cannondale Synapse Carbon 4 Chalk
- Lightweight, compliant, sleek and aerodynamic – the Synapse carbon frame with StashPort downtube storage compartment
- Shimano 105 Di2 – impressively smooth gear changes thanks to Shimano's electronic 2x12-speed drivetrain
- DT Swiss 470 rims with Vittoria Rubino Pro IV 32C tyres – grip, durability and speed
- Cannondale C1 Aero 27 carbon seatpost – speed meets comfort
- Fizik Vento Argo R5 saddle – ergonomic comfort with pressure-relieving channel
What it's made for
Comfortable and performance-oriented road bike rides, extended all-day tours as well as fast group rides – developed for long distances, high speed and lasting comfort.
Highlights
Clearance for wide tyres
The generous tyre clearance with up to 48 mm tyre width at the front and 42 mm at the rear, with at least 4 mm clearance on each side, makes the Synapse a versatile road bike for a wide variety of road conditions.
StashPort + StashBag
The integrated StashPort storage compartment in the downtube is located under the bottle cage and allows tools and essential utensils to be safely carried. It is complemented by the custom-fit StashBag for tidy and practical storage.
D-ynamic
The D-shaped profile of the seatpost improves aerodynamics while increasing vertical compliance. The result is a noticeable reduction in muscle fatigue on long rides.
Delta steerer tube
The V-shaped Delta steerer tube enables fully internal cable and wire routing, ensures a tidy cockpit and reduces the frontal area of the head tube for lower drag and an elegant look.
Strong performance under real conditions
The lightweight frame with tube profiles optimised in the wind tunnel and an exceptional stiffness-to-weight ratio is designed for speed, endurance and comfort. Conceived for a wide variety of roads, also proven under extreme long-distance loads.
More comfort
The further developed carbon layup offers around 20% more comfort compared to the predecessor model and ensures a controlled, pleasant riding feel even on rough surfaces.
Fits like a glove
The Proportional Response Design precisely tunes the carbon layup and geometry to every frame size and guarantees balanced handling as well as an optimal fit for riders of all heights.
Always have everything with you
The StashPort storage compartment in the downtube significantly expands the transport options on long rides. In combination with the high tyre clearance, new options arise for extended tours off perfect roads.
