Product Description

Do your friends ask if you intend to ride the chairlift when you invite them out for a ‘few’ park laps? Do your top routes frequently involve pushing up and down trails that aren’t on any map? Do your favorite rides begin or end with headlamps, an ice chest and great friends? Does your bike have to do everything well to get you there and back again? If you think you might be this rider, then Occam should be your bike.

Orbea Monocoque Race (OMR) frames blend high modulus fibers and high strength fibers exclusively. Prepreg carbon sheets are laser cut to minimize excess materials and overlap, and hours of pre-moulding ensure optimal compaction with the smallest amount of carbon. A full EPS (Expanded Polystyrene) mold helps eliminate wrinkles and voids.

The right side support strengthens and stiffens a high-stress area. Instead of using a less-efficient “shock tunnel” the Occam design offsets the shock to the left side of the frame, allowing the asymmetrical support to follow a more direct path. This straight line that closely follows the shock mounting is the most efficient way to neutralize suspension forces on the front triangle.

The asymmetric/offset design offers unique advantages beyond stiffness and low weight. The shock is mounted in a position that offers incredibly easy access to damper controls and the tidy design leaves room for bottle with easy left-side access.

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:

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

 

 


Frame material

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

Aluminium

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

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)
