About the build
Pure Shimano 105 throughout — no mixed components. Well-proportioned spec sheet with minimal tier variation across component groups. Compared with equally well-specced road bikes, the price is on the low side. The manufacturer doesn't publish geometry for this model, so we make no claim about fit or handling.
Worth knowing
- Electronic shifting is still not standard at this price

Manufacturer's description
Wireless brains meet all-road brawn. Synapse Carbon 4 runs Shimano 105 Di2 for a shifting experience that feels straight off the pro tour, minus the bank loan. The frame delivers that signature Synapse ride—quietly fast, endlessly composed—and plays nice with wide tires, fenders, and long days. Call it the sweet spot between Sunday speed and weekday practicality.
