## Measured asking price by model year (113 real UK listings that state a model year)

Median last-advertised asking price per model year. These are asking prices, not confirmed sale prices.

These are a different set of listings from the headline figure above: 126 of the 416 listings state a model year, and their median is £1,050. Compare a model year below against £1,050 rather than against the all-listings median.

## Overview

The Synapse is Cannondale's endurance road bike and it has been a favourite of UK sportive riders for years. It competes directly with the Trek Domane, Specialized Roubaix, and Giant Defy. With 85 used listings tracked at an average price around £3,330, it offers solid value in the endurance category.

Cannondale takes an interesting approach with the Synapse. Rather than adding suspension systems, they have focused on frame engineering to build compliance into the carbon layup itself. The frame flexes where it needs to absorb vibration and stays stiff where it needs to transfer power. It is a clean, maintenance free approach to comfort.

The latest Synapse also includes the SmartSense integrated light and radar system on some models, which is a genuine safety innovation for UK riders dealing with dark winter commutes and busy roads. Most used models sit between £1,940 and £3,910.

## What it's like to ride

Smooth and composed. The Synapse soaks up road vibration through frame compliance rather than mechanical systems, and the result feels natural. There is no suspension bob or disconnected feeling. It just rides like a comfortable road bike that happens to smooth rough roads.

The geometry is relaxed enough for all day comfort without feeling sluggish. The Synapse handles well in groups, descends confidently, and climbs respectably. It is not as sharp as the SuperSix EVO but it is not trying to be. On a century ride over mixed UK roads, the Synapse is one of the most pleasant bikes you can ride.

## Who it's for

Sportive riders and century chasers. Commuters who want a performance bike that can handle UK roads year round. Riders who prefer low maintenance simplicity over complex suspension systems. Anyone who found a race bike too uncomfortable but does not want to give up performance entirely.

## Good points

- Frame compliance provides comfort without any mechanical systems to maintain
- SmartSense integrated lights and radar on newer models
- Good value compared to the Domane and Roubaix
- Takes mudguards and wider tyres for UK year round riding
- Cannondale dealers across the UK for support

## Considerations

- Less vibration damping than the Domane with IsoSpeed
- SmartSense system adds electronics that can fail or need updating
- Cannondale Ai offset limits aftermarket wheel options on some models
- Lower spec models come with basic wheels that benefit from upgrading

## Year guide

The 2022 redesign brought SmartSense, dropped weight, and improved tyre clearance. These are the best Synapses yet. The 2018 to 2021 generation is still an excellent bike and significantly cheaper on the used market. Pre-2018 models are getting dated. For the best value, a 2022 Carbon 4 or a 2019 to 2020 Carbon Ultegra are strong choices.

## FAQs

### Is the Synapse better than the Domane?

The Domane has better vibration damping with IsoSpeed and stronger brand prestige. The Synapse is simpler (no mechanical parts to service), potentially lighter, and the SmartSense system is a genuine safety benefit. Both are excellent endurance bikes.

### What is SmartSense?

It is an integrated system with front and rear lights plus a Garmin Varia style rear radar, all powered by a single battery in the downtube. The lights auto adjust to conditions and the radar alerts you to approaching vehicles via a compatible head unit. It charges via USB and lasts around 5 to 6 hours.
