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

You should allow 48 hours to receive your order, e.g if your order is placed on a Monday it will go out on Tuesday for delivery Wednesday. If you happen to be out at the time of the delivery a card will be left.

Under the Consumer Rights Act you have an early right to reject goods that are unsatisfactory quality, unfit for purpose or not as described, and get a full refund.

But this right is limited to 30 days from the date you took ownership of the goods (this could be the date of purchase or the date the goods were delivered to you - whichever is later).

After the initial 30 days, you can't demand a full refund in the first instance, but you still have the right to a repair or replacement.

In addition to our Returns Policy, under the Consumer Contracts Regulations, you have the right to cancel your order up to 14 days from the day you receive your goods if you are an online, mail or telephone order customer. You then have a further 14 days from the date you notify the retailer of your cancellation to return the goods.

Warranty lengths for Caygill frames are material specific: Steel 5 years, Alloy 2 years, and Carbon 2 years. Faulty items will be accepted and processed according the Manufacturer's terms and conditions. Some items do have to be sent back to the manufacturer first before we can agree on any replacement/refund. This does not affect your statutory rights.

Please allow 2-3 working days for us to process your return to us.

Deposits for items requested to be stored in house for any period of time are non refundable. This includes bikes stored for future collections and items specifically ordered in for customers which we would not normally carry in stock.

All bikes purchased from us via our website that we are shipping out will need some assembly as we can only send bikes out in their original boxes with our Courier. The element of building varies from each brand of bike purchased. Bikes purchased in Store will be fully built ready for you to ride away and with a Free Service taken within 2 months of purchase date.

Here’s to long rides. Climb higher mountains, skip the shortcuts. This buttery smooth endurance road bike helps you do more of what you love.

Features:

  • Functional simplicity - Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a “less is more” experience for modern endurance road riding.
  • Engineered compliance - Advanced-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimizes fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.
  • Total control - New Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide, hookless carbon rims (22.4mm inner width) are optimized for high-volume tubeless tires (up to 38mm), and a 40mm rim depth offers stable, predictable handling in crosswinds.
