💡 How does it compare to the SuperX and SuperSix
Choose the Synapse if you want one road bike that can handle it all — fast on pavement, calm on gravel, and comfortable enough to ride every day.
Go SuperX if your rides start where the tarmac ends — it’s built to dominate gravel races and off-road adventures with serious capability.
Pick the SuperSix EVO if speed is your top priority — it’s sharp, aggressive, and made to slice through road races, crits, and KOM battles.
