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

Returns & Exchanges Policy Summary

We offer a 14 day returns period from the date of receipt.

It is your responsibility to ensure that the item is returned to us safely and securely, we suggest that you use a recorded postal/courier service. Please ensure that the service you use covers the value of the goods in the parcel.

We are unable to accept returns where the goods or packaging has been used, lost, damaged or is otherwise not in the condition you received it in. Bikes must be returned in a securely packaged bike box.

If you would like us to arrange a collection via courier, then we can do so at a cost of £50. Should you fail to be present for an arranged collection, you will be charged £20 to rebook.

We will refund up to £10 for private postage of faulty or damaged items.

If you would like to exchange an item, we will happily send out a replacement product once the original has been returned.

We are unable to offer a refund without proof of purchase.

We cannot accept returns without a completed returns form.

Signing for delivery receipt of items that have clearly been damaged by the courier is the responsibility of the receiver.

Items that are damaged during a return as a result of inadequate packaging will be declined and returned to you, or charged for.

Faulty Goods and Warranties

If the item that has been received is faulty, damaged or not as described then we will cover the cost of return postage (up to £10) and offer a refund or exchange. In these instances, we would always recommend using our own shipping services.

Important information to note about returning faulty, damaged or not-as-described items:

Pauls Cycles issue no warranties, all warranties are issued by manufacturers. For this reason, we may need to send your goods to the manufacturer for inspection before taking any action. Please see the relevant manufacturer's website for full warranty information.

Only products that are faulty, damaged or not as described by ourselves are eligible for returns/exchanges. If damage has been caused through wear and tear, improper care or some other factor beyond our control then it will not be covered.

Once a faulty item has been used, or if the packaging has been damaged it can still be returned to us, however, we - and the manufacturer - reserve the right to offer a repair, replacement or partial refund.

Remember it is your responsibility to ensure that returned items are packaged appropriately - any damage caused in transit [as a result of inadequate packaging] will be chargeable.

We cannot accept any cycle warranty claim or return for incorrect pedal fitment or damage to crank arms caused by incorrect pedal fitment as described in the helpsheet supplied with all of our bikes.

If the wheels on the bike you've ordered become untrue through use, or the gears need readjustment after initial use, this unfortunately not covered under warranty.

Power and control are the twin keys to unlocking speed.

The Phenix C:68X SLT's lightweight and comfortable one-piece bar/stem combo puts everything you need at your fingertips. SRAM's XX SL Eagle Transmission groupset serves up fast, ultra-precise electronic shifts over a huge gear range, and the XX SL Eagle crank is power meter-equipped so you can keep an eye on your performance. Fast-rolling Schwalbe Racing Ray and Racing Ralph 6cm (2.35") tyres wrapped around light, stiff, and strong Newmen Phase 30 wheels deliver your power to the trail, whilst a Fox Float 32 Factory SC fork with remote keeps everything planted and pointing in the right direction. To maintain speed into every corner, Magura's powerful MT8 SL brakes with a 180mm rotor up front are fitted.

Phenix C:68X frames are designed for fast cross-country racing. These frames use premium C:68X carbon for the ultimate in low weight, high strength, and ride comfort. The seat tube junction is redesigned to incorporate an integrated seat clamp. This, along with Internal Cable Routing, complements the frame's clean aesthetic and elegant, organic lines. An adjustable angle headset allows you to tweak the bike's handling to suit your own taste.

Size Guides are a great way to help you find the right bike, but we always recommend visiting our store to view and sit on the bike in person where possible or speaking to our advice team.

This Size Guide is based on an average build, if you have shorter arms or longer legs for example you will need to consider this when purchasing a bike. If you are between sizes, we always recommend sizing down as a smaller bike can be made bigger with adjustments. Stem length, Saddle height, Handlebar width and even Crank length can be changed to achieve the ideal riding position. See here for our general bike sizing guide.
