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 costing a fortune. The full carbon frame impresses with the familiar Synapse riding experience - quiet, fast, particularly comfortable - and also cuts a fine figure with wide tyres and mudguards on the long haul. Let's call it the happy medium between a fast Sunday ride and suitability for everyday use.
Features - Cannondale Synapse Carbon 4 Chalk
- Light, compliant, slim and aerodynamic - the Synapse carbon frame with StashPort down tube storage compartment
- Shimano 105 Di2 - impressively smooth gear changes thanks to the 2x12-speed electronic shifting system from Shimano
- 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 cut-outs
What it's made for
Comfortable and performance-orientated road bike rides, extended all-day tours and fast group rides - developed for long distances, high speed and lasting comfort.
Highlights
Space 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 range of road conditions.
StashPort + StashBag
The integrated StashPort storage compartment in the down tube is located under the bottle cage and enables tools and important utensils to be carried safely. It is complemented by the custom-fit StashBag for tidy and practical storage.
D-dynamic
The D-shaped profile of the seatpost improves aerodynamics and at the same time increases 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 routing, ensures a tidy cockpit and reduces the frontal area of the head tube for less drag and an elegant look.
Strong performance under real conditions
The lightweight frame with wind tunnel-optimised tube profiles and an exceptional stiffness-to-weight ratio is designed for speed, endurance and comfort. Designed for a wide variety of roads, proven even under extreme long-distance loads.
More comfort
The advanced carbon layup offers around 20 % more comfort compared to the previous model and ensures a controlled, comfortable ride even on rough surfaces.
Fits like a glove
The Proportional Response Design precisely adjusts the carbon layup and geometry to each frame size and ensures balanced handling and an optimum fit for riders of all sizes.
Always have everything with you
The StashPort storage compartment in the down tube significantly expands the transport options on long rides. In combination with the high tyre clearance, this opens up new options for extended tours off the beaten track.
