Product Description

The MTR 8.9 offers a beautifully balanced specification, using the same frame geometry and rear suspension set up as the 9.0, but with our X7 triple butted alloy. Aggressive trail riding places big demands on your equipment, and the high-performing kit on the MTR 8.9 is more than up to the task.

SRAM provide their NX Eagle drivetrain, which combines a 12 speed 11-50t cassette with a 32T chainring to give plenty of range to tame steep climbs and pedal hard down the other side. Powerful 4 Piston SRAM Guide T brakes with 180mm rotors will keep your speed under control when you need it too.

Soaking up bumps and keeping wheels planted on the floor is taken care of with RockShox’s Gold 35 fork, and Deluxe Select+ shock in a custom tune. As the name suggests, the Gold 35 has a stiff 35mm chassis giving great steering precision throughout its 150mm travel. Steering control is further enhanced with a 780mm handlebar and 45mm stem, giving great stability and leverage to get the bike turned in hard.

Maxxis Minion DHF and DHRII tyres give great grip for hard cornering and braking and are mounted on 30mm internal width Boardman rims, needing only a tubeless conversion kit to ditch the hassle of inner tubes forever.

Finally, a Satori Sorata Pro dropper post with 125mm travel on size S and M, and 150mm in size L and XL will let you move around easily on the bike with the saddle dropped out of the way on technical terrain.

Key Features:

  • New 29er platform with 145/150mm travel and UK trail focussed geometry
  • RockShox 35 Gold fork and Deluxe Select+ shock give outstanding, easily tuneable suspension performance
  • SRAM Guide T 4-piston brakes and 12 speed NX Eagle gears perform flawlessly
  • Maxxis Minion DHF & DHRII tyres on wide Boardman rims grip without folding in the corners
  • Satori Sorata Pro dropper post allows maximum body movement on the bike

Occasionally, without notice, manufacturers change product design and/or specifications.

Full Sus MTB Guide


Is a full-suspension mountain bike right for me?

If you’re new to the world of cycling, we highly recommend taking a look at our bike buying guide overview or our mountain bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a full suspension mountain bike, there are a few things to look out for which can help you to work out the quality and performance you can expect from a particular model.

Suspension travel & usage

Depending on the type of mountain bike riding you’ll be doing, you may want to have longer or shorter suspension travel on your bike:





Up to 120mm


Lightweight & efficient pedalling for long-distance rides

Short travel is less capable on rough & demanding trails with large jumps & drops

120 – 150mm


Lightweight, balance of climb-friendly efficiency & rough-descent capability

More weight than a shorter travel bike & less efficient climbing. Less capable on descents than a longer travel bike



Capable of covering difficult & technical downhill sections. Wide enough gear range for climbing

Heavier & significantly less efficient at climbing compared to shorter travel bikes

180mm +


Designed for highly technical & high-speed descents, with big drops and large jumps

Heavy, and inefficient at climbing. Limited gear range means most climbs will require pushing the bike



Frame material

Full-suspension MTB frames are mostly made from either aluminium or carbon fibre, with each material having its own benefits & drawbacks.


Aluminium is lightweight, stiff, strong, and easy to manufacture. Manufacturers often develop their own aluminium alloys, such as ALUXX by Giant. Aluminium is found on a wide range of bikes, from entry-level & enthusiast bikes, right the way up to top-spec racing bikes.


Carbon fibre is lighter, stiffer, stronger, and more expensive than aluminium. The most affordable carbon bikes typically use medium strength carbon fibres, while the most expensive bikes use stronger ‘high modulus’ carbon. Carbon fibre frames are found on enthusiast-level bikes, right up to high-performance bikes designed for racing.

Groupset & drivetrain

Mountain bike groupset components are typically supplied by either Shimano or SRAM, with additional manufacturers like Formula, Hope, Magura, Tektro and TRP supplying brake systems. Shimano & SRAM both produce a range of groupsets to suit different budgets. The hierarchy table here compares the different Shimano & SRAM groupsets to determine which bikes offer the best performance.

A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen. A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifters
  • Front & rear derailleur
  • Chain
  • Cassette

Wheel size

You’ve probably noticed that a lot of mountain bikes come in a choice of wheel size, mainly a 27.5 inch wheel (also known as a 650B wheel) or a 29inch wheel (known as a 29er). Although there are still bikes which use 26 inch wheels, these are gradually being phased out on all but the smallest bikes. The difference between these wheel sizes can have a dramatic effect on the way a bike feels and handles out on the trail.

27.5in/650b Wheels

27.5inch wheels are smaller and lighter than 29er wheels, which makes them more agile and gives the bike a more responsive & playful nature. On the other hand, the smaller wheel size rolls less efficiently than the larger size, making the bike more prone to losing speed over rough ground and making it a little slower when climbing.

29er Wheels

29er wheels have a bigger rolling radius which makes them naturally smoother over rough ground. For this reason, a 29er mountain bike often requires less suspension travel than smaller wheeled alternatives. The downsides are an increase in weight, and the larger diameter wheels generate stronger gyroscopic forces, making the bike more stable, but less agile and responsive whilst manoeuvring.

26in Wheels

26 inch wheels were once the go-to wheel size on adult mountain bikes. However, they are now typically only found on the smallest frame sizes, and on junior bikes. 26 inch wheels are lightweight and give the bike very agile handling. The downsides to 26 inch wheels are their poor rolling resistance on rough ground, and the reduced contact patch due to the smaller wheel circumference.

Suspension components

Mountain bike suspension components (i.e. the fork or rear shock absorber) are also a way to identify the quality of a bike. While Fox and RockShox are the most common manufacturers, there are a number of brands producing suspension components for mountain bikes.

Entry level full suspension mountain bikes (up to approximately £1300) may come supplied with a fork & rear shock supplied by SR Suntour, X-Fusion or RockShox. These components will allow a limited amount of adjustment, including:

  • Coil spring preload / air spring pressure adjustment
  • Lockout switch
  • Rebound damping adjustment on models towards the top of the price range.

Mid-range & enthusiast bikes (up to approximately £3500) use components from brands including Fox, RockShox and Manitou. At this level, suspension components have features like:

  • Preload adjustment / air spring pressure adjustment
  • Rebound damping adjustment
  • Lockout switch
  • Multi-position ‘mode’ switch
  • Components towards the top end of the enthusiast price range may also feature compression damping adjustment as well.

Top of the range & competition spec bikes (over £3500) also use components from Fox, RockShox & Manitou, with a few select models using parts from Ohlins. At this price, suspension components have features including:

  • Coil spring preload adjustment / air spring pressure adjustment
  • High & low speed rebound damping adjustment
  • High & low speed compression damping adjustment
  • Lockout switch
  • Multi-position 'mode' switch
  • Advanced low-friction coatings (e.g. Fox’s golden-coloured Kashima coating)
