It’s hard not to go fast on the Orbea Oiz M10 XC mountain bike. The super lightweight carbon full suspension frame has 95mm of efficient travel and is matchd to a 100mm travel fork. Fox factory suspension is found both front and rear, complete with slippery Kashima coating. Making sure the climbs are a breeze, SRAM offers 12 gears with its Eagle drivetrain. Mavic Crossmax Elite wheels are fantastic, balancing weight and strength, and in 27.5” size, deliver nimble handling.
Key Features:
Oiz is engineered for one purpose – Speed
The kind of lung-burning, cross-country efficiency that is expected from a racing bike, matched with DNA that devours rough terrain and leaves traditional hardtails behind. Lap after lap, Oiz responds eagerly to each climb, every rocky, root-filled descent, pushing you to ride faster. Oiz is the ultimate advantage – not a machine that rides in the middle of the pack – Oiz was Born to Win.
Advanced Dynamics - Advanced Dynamics is not a design, but a development process. Our unique method transforms virtual models into real, highly-refined machines - Bikes for demanding riders that are faster, more fun to ride and far beyond ordinary.
Boost - Oiz becomes more precise and responsive with the increased rigidity of a 12mm through-axle system. The Boost 148 standard widens rear axle spacing to 148mm which moves the chainline outboard by 3mm and increases the space available at the bottom bracket.
UFO - We've done away with the pivot point at the rear axle. The flexible seat stay design creates an ultralight bike that requires little maintenance and offers stiffness and acceleration like you've never felt in a full suspension bike.

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.
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:
|
Travel |
Usage |
Pros |
Cons |
|
Up to 120mm |
XC |
Lightweight & efficient pedalling for long-distance rides |
Short travel is less capable on rough & demanding trails with large jumps & drops |
|
120 – 150mm |
Trail |
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 |
|
150-180mm |
Enduro |
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 + |
Downhill |
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 |
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.
A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen.
A complete groupset comprises of the following parts:
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.
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.
27.5inch 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 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.
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.
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:
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:
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:
