Size Guide
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

If you are not completely satisfied with your purchase, or simply no longer want the item, you can return it for a full refund or exchange.

Giant - Reign SX Full Suspension Enduro Mountain Bike in Moonstone

Season:2025

Brand:Giant

Code:9125006MoonBRN

Big hits and all-out descents. This trail-crushing enduro machine delivers confidence and control for the rowdiest terrain. Its mixed wheel size, with a 29-inch front and 27.5-inch rear, blends stability and speed with agility that pops.

Features:

  • Race-bred suspension -Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 190mm travel fork. The trunnion mount rear shock has a longer stroke (65mm over 60mm on the previous generation) while the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall frame weight.
  • Adjustable enduro geometry -Flip chip adjustability lets you switch between two settings depending on the terrain. You can select a 63.1 or 63.5-degree head angle and corresponding 77.9 or 78.3-degree seat tube angle, resulting in a 25 or 19mm bottom bracket drop (size medium) to fine-tune handling for varying trail conditions and riding style.
  • Mixed wheel size -A 29-inch front wheel provides speed, stability and front-end control on rough, technical trails. A 27.5-inch rear wheel adds agility and maneuverability to help riders rail corners, pop over features and show off their style.

  • Weight
    The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
