X-Caliber 8 is a cross-country mountain bike made for fast laps and long days on the trail. It's built with special attention to value and the parts that make the biggest difference in performance. A 1x Shimano drivetrain, RockShox fork and hydraulic disc brakes make it a great choice for new mountain bikers and XC racers searching for fast, fun, singletrack adventure.

You're looking for a fast mountain bike for singletrack ? one that's fully capable of taking on races, marathons and competitive group rides. You want something that is reliable and fun with dependable, lightweight parts.

A lightweight aluminium frame, a RockShox Judy SL 100 mm suspension fork with a TurnKey lockout and an air spring that's lighter and more adjustable than a coil spring, tubeless-ready wheels with Boost141 hub spacing and a Shimano Deore 1x12 drivetrain with a wide-range cassette.

With the X-Caliber 8, you're getting a performance frame paired with performance parts, like a RockShox air fork and 1x Shimano Deore drivetrain. Plus, it's equipped with durable, lightweight alloy rims that save weight and are easy to upgrade to tubeless.
- It has the price of a more basic hardtail, but the parts and performance of a more expensive one
- The frame is fully compatible with higher-end parts, like race wheels and a dropper post, if you ever find the need to upgrade
- Smart Wheel Sizing means you'll get the fastest wheel that fits (29? wheels on larger frames, 27.5? wheels on smaller frames)
- The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter

High tech frame
The Alpha Gold Aluminuum frame is packed with features that make your ride better. A tapered head tube gives you more precise, confident handling on the front end, while Boost 141 rear hub spacing gives you shorter chainstays for more nimble handling at the back.

Built for speed
X-Caliber is a classic XC hardtail with quick-handling geometry, weight-conscious parts and just enough suspension to take the edge off bumps. These models are built for efficiency, making them great for racers or anyone else who wants to cover more ground in less time.

Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.

GET UP TO 39% OFF THE COST OF YOUR NEW BIKE: HAPPY CYCLE TO WORK DAY

The UK’s Cycle To Work Scheme has been in place for over 20 years now, offering fantastic discounts to tens of thousands of riders.

The Cycle To Work Scheme, is offered through many thousands of employers in the UK and applies to bikes of all types, whether it’s road, MTB or hybrid, and that includes e-bikes too.


About the Cycle To Work Scheme

Introduced in 1999, the scheme aims to encourage employees to commute on their bike for environmental, traffic congestion and health reasons. It also enables companies to demonstrate that they’re looking after the wellbeing of their people.

Obviously, you’re supposed to use the bike for commuting – and we are massive supporters of getting to work this way – but it’s fine to buy a bike that’s built for the trails. Your employer owns the bike until you pay the final ownership fee, which is based on the “fair market value” of it at the end of that period.

As well as your new bike, you can use the scheme to buy accessories, such as helmets and bags, though these have to be ostensibly for your commute. So, no full face masks, for example. If you don’t have a lock, we strongly advise that you get one along with your bike as you’re liable for the Cycle To Work payments, even if it gets stolen while you’re paying it off.


How does the Cycle To Work Scheme work?

This is a salary sacrifice scheme for people aged 18 and over where the monthly payment for your bike is taken out before tax and National Insurance are deducted. Because your contribution is taken before tax, you pay off more per month for less. So, for a bike costing £1,200, £100 is taken from your salary every month but it only costs you £68 because the other £32 would have normally gone to the tax man, right? So, you pay 12 instalments of £68 and a final ownership fee of £300, totalling £1,116. If your salary puts you in the higher tax brackets, you actually save more but you get the gist.


I’m interested. What do I need to do?

Firstly, find out which scheme your employer is enrolled in and therefore where you can buy your bike from. We work with a number of Cycle To Work providers, including cyclescheme.co.uk, cycleplus and Bikes for the NHS.

Then you need to speak to your HR department and request a certificate, bring it to us and we’ll redeem it against the cost of your bike and accessories. The salary sacrifice commences from your next pay packet.

To get a bike on the scheme, your employer needs to sign up to a provider. If they’re unsure about how to do this, send them to us and we’ll help.
