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

Earn Rewards

When you purchase this item, you will earn of rewards points to spend on your next purchase from us. You can spend your Rewards balance in-store & online.

28 day returns

We always want you to be happy with your online purchase, but if for any reason this isn't the case, then CJ Performance Cycles offers a 28 day returns policy.

If your order has not yet been dispatched, we should be able to cancel it immediately and process your refund. If, however, you order has been processed, you have 14 days from receipt of goods to inform us of your intention to cancel your order. You then have a further 14 days to return the goods to us. Returns received outside this 14 day period will not be accepted and will be shipped back to you.

Any items returned must be in unused condition and in the original packaging, which should also be in as-new condition. Any signs of overhandling will result in a charge against the amount refunded.

Items must be returned at your own cost, and we recommend that you use a reputable, insured service as the goods will remain your property until your order is refunded. Any items returned without proof of postage that are lost in transit are not the responsibility of CJ Performance Cycles, and we reserve the right to cancel any refunds in this scenario.

A refund will be issued once the products have been received and inspected by CJ Performance Cycles, usually within 14 days.

2023 Giant Reign Advanced Pro 0 Enduro MTB - Messier/Carbon

Season:2023

Brand:Giant

Code:2311099

Race-tuned control. Carbon precision. Built to dominate enduro terrain.

The 2023 Giant Reign Advanced Pro 0 is the flagship enduro bike for riders who demand uncompromising performance on steep descents, technical climbs, and high-speed trails. Whether you're racing enduro or pushing limits on alpine terrain, this bike blends carbon construction, elite-level components, and adjustable geometry in a stealthy Messier/Carbon finish.

Its Advanced-grade composite frame features Maestro rear suspension with 160mm of travel, paired with a 170mm Fox 38 Factory fork for plush responsiveness and aggressive control. The Fox Float X2 Factory rear shock offers high-speed compression and rebound adjustability, tuned for enduro racing.

The SRAM X01 / XX1 Eagle AXS wireless drivetrain delivers crisp, cable-free shifting with a wide gear range, while Shimano XTR hydraulic brakes provide powerful, consistent stopping. 29" carbon wheels with Maxxis Assegai and Minion DHR II tyres offer grip and rollover confidence on loose, rocky terrain. The flip chip Maestro geometry lets you fine-tune head angle and bottom bracket height for low, mid, or high settings—ideal for terrain-specific setup or mullet compatibility.

Integrated down tube storage, internal cable routing, and Quarq TireWiz pressure sensors round out a build that’s ready for elite-level racing and all-mountain domination.

Professional Opinion

Advanced Composite
Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
Advanced Forged Composite
A state-of-the-art high-pressure moulding process is used to produce complex-shaped carbon fibre components that are lighter, stiffer and stronger than similar components made from aluminium. This technology is used in critical performance parts such as Maestro Suspension rocker links.
Maestro Suspension
Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
Overdrive
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
Flip Chip - Maestro 3
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It’s available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
