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.

Hassle free returns

Any item, except food, face masks or e-gift vouchers (full e-gift vouchers T&Cs are listed on the respective product pages) can be returned to us for any reason within 90 days, provided that the item has not been used or fitted and is returned in its original packaging with valid proof of purchase. It is recommended that you use a recorded delivery service to ensure your items are received by us. We cannot assume responsibility for items that are lost in the post.

Online or in-store purchases can both be returned to any store free of charge or can be returned by post after completing the online returns form. If you are returning an item due to a fault, we will refund your postage.

Please note:

1. If the items we have sent you are faulty, damaged or not as we described, we will cover the cost of collection and the delivery of the correct item.

With a lightweight frame, 130mm suspension fork and 27.5 wheel with high-volume tyres, this hardtail offers loads of traction, speed and fun on the trail.

Features & Benefits:

  • Trail tuned design: Balanced geometry with a 75-degree seat tube angle puts the rider in a powerful pedalling position on climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents.
  • Responsive handling: Lightweight ALUXX SL aluminium hardtail frame offers agile acceleration and manoeuvrability to help riders climb, corner and hammer the flats with efficiency and speed.
  • Smooth control: Giant Crest 34 suspension fork with 130mm of travel absorbs roots, rocks and ruts. Grippy, high-volume tires boost traction on rugged terrain. And a dropper seatpost with handlebar remote lets you adjust saddle height on the fly for confident positioning on changing terrain.

    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.
