Highlights:

KONA 6061 ALUMINUM

Kona 7005 and 6061 Aluminium alloys are used extensively throughout our fleet of mountain and asphalt bicycles. A tough, durable, light alloy, both Kona 7005 and 6061 deliver fantastic, reliable performance that lasts for thousands of rides. Much of our 7005/6061 tubing is butted and/or formed, meaning the tubing’s wall thickness can be increased or decreased, as well as shaped, so we can fine-tune a particular frame’s strength and ride characteristics depending on its intended application.

INTERNAL HEADSET

Bearing cups are actually pressed into the frame and are easily removable. An internal headset also reduces stack height, so the height of the stem and bars are more adjustable, giving the rider the best fit possible.

TAPERED HEAD TUBE

More girth at the bottom of the head tube better distributes shock force, prolonging the bearing life of the headset itself and eliminating brake shudder, while providing confident steering performance. The inherent strength of its triangular design also means a stronger steering position and improved balance, giving the rider more control in rough terrain. A zero-stack, tapered head tube also puts strength where the load is going—into the lower headset cup—maximizing bearing durability where it’s needed.

12x157mm AXLE

12x142mm, 12x148 and 12x157 rear axle standards provide two major advantages to the Kona rider: the 12mm diameter of the rear axle provides the rear hub and frame with a stiff interface, while the 142/148/157mm outer diameter of the hub allows the wheel to be quickly and properly positioned in the frame before the rear axle is inserted. For 2017, you’ll see the 12x148 Boost standard in the mix. Boost spacing provides more tire clearance at the chainstay yoke, while the rear wheel is stiffer and more durable relative to a 12x142 thru-axle.

BEAMER INDEPENDENT SUSPENSION

Built to be off-the-top progressive, Beamer Independent Suspension helps the bike to stay higher in the travel and recover from hits more quickly. The Operators are instilled with what our product managers like to call “pure shock movement,” whereby the shock is protected from side load. Designed to be highly tuneable and extremely durable, the Beamer IS is our version of greased lightning.

27.5" WHEELS

The benefits of the 27.5-inch wheel are simple: they roll over obstacles and track better than 26-inch wheels, but are more manoeuvrable and nimble than 29-inch ones.

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

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
MTB Groupsets

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.


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)
