Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Road reimagined.

Go long, go short, go fast. This is WorldTour performance for real world rides.

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.

  • Lightweight, smoothly compliant, sleekly aero Synapse carbon frameset with StashPort downtube storage
  • Shimano 105 Di2 – Impressively smooth shifting from Shimano's journeyman electronic 2x12-speed drivetrain
  • DT Swiss 470 rims with Vittoria Rubino Pro IV 32c tires - grip, durability, and speed
  • Cannondale C1 Aero 27 Carbon seatpost - speed meets comfort
