Product Description

Anyone who ever dreamed of a pro-cross-country racing career has dreamt of the Spark RC 900 Pro. The 1x-specific Spark RC frame design and lightweight, hyper-efficient TwinLoc Suspension System are made for pure, on-course performance. The Pro build includes a Shimano XTR 12-speed drivetrain and XTR brakes and is made to go the distance with premium Syncros components completing this race-worthy package in style.

Technologies:

Evo-Lap Technology:

With the proper selection of materials, eighty percent of the work to create a frame is done. But the remaining twenty percent requires most of our efforts. For this reason, our choice of the most advanced carbon fibres in the market is followed by intensive use of specific tools, like FEA(finite element analysis) software, to map out the carbon lay-up.

With FEA software, we can simulate different forces on a virtual model of the frame and adjust the frame construction accordingly. FEA software enables us to create complete virtual prototypes incorporating all the physical phenomena that exist in real-world environments.

With our Evo-Lap technology, we model the frame to optimize the surface area, simulate tube structures with different ply orientations, observe the results of using different configurations, and test the stress distribution in different areas of the frame. Thanks to this extensive computer modelling, we’ve optimized the carbon layers in all the parts of our frame. When the parts were bonded together in the first prototypes, the result was a super light and compact frame without a sacrifice in the stiffness, comfort or impact resistance. The entire range benefitted from our EvoLap technology.


Twinloc Suspension System:

With TwinLoc, a rider can effectively control the complete frame, fork, and shock as a system. Why does this matter? A bike with 150mm of suspension travel, correctly set up, has more sag than a bike with 130mm. It's that extra travel that makes it more fun to ride and more capable on the descents, but the greater sag has an oversized effect on the bike's geometry and climbing performance. That's where TwinLoc matters.

TwinLoc helps manage the sag effect in several ways. Whereas most systems only increase low-speed compression in an effort to gain pedalling efficiency, TwinLoc allows us to not only change compression damping but also to change the spring curve, dynamically altering the geometry of the bike. In Trail mode, the shock is not only firmer, but it has dynamically less travel. The bike sits higher, maintains a steep seat angle for those climbs, and becomes more agile. We also offer a third, full lockout mode for going up in the most efficient manner possible.

These unique settings optimize climbing geometry, even on longer travel bikes. We can eliminate the "long travel effect" that can rob your pedalling efficiency, but we're not robbing you of the full-fun, 150mm travel when you point it downhill. From a race setting to a lunch ride to an after-work trail shred, being able to switch from mode to mode depending on a trails profile at the push of a lever is paramount to riding faster and having a damned good time.


ICCR Cable Routing:

On the Scale, Spark, Genius and Ransom, to provide a clean look and a functional solution for all the different control cable standards on the market, cable routing is fully internal and designed for full length cable housing. Routing the cables internally omits bulky external hardware and looks cleaner. The cables can endure a longer lifetime as they are protected within the frame. The entry points are machined alloy removable inserts that come along with the frame and can be chosen according to the setup of the bike. Assembling an electronic group or a dropper post will not be a problem and the look will always be clean-cut.


SW Dropouts:

On the Scale, Spark, Genius, Ransom and Gambler we’ve redesigned all the parts that can give us significant benefits in terms of performance and functionality. On the previous model, the support of the dropout was a bulky additional part moulded to the carbon chainstay. The new dropouts are designed to be integrated on the thru-axle system thanks to a hollow tubular design that allows a simple and lightweight structure. Available for SRAM and Shimano DM derailleurs, this dropout increases the stiffness and avoids damage to the frame in case of impacts on the rear derailleur.


Asymmetric Design:

The Spark down tube shock and linkage are clearly asymmetric when looking from the top of the bike. Carbon fibres achieve their full potential when used in smooth straight lines. Off setting the shock slightly to the left-hand side of the bike gives a clean and continuous structure from the down tube through the shock mount to the main pivot.


Axle Tool:

Working together with DT Swiss, we completely revisited the shape of the thru-axle lever to make it more ergonomic and to perfectly fit to our frame. Additionally, we introduce a new multifunctional tool integrated on the inner part of the thru-axle itself. This 25T torx wrench is easy to reach and ready to be used for quick adjustments on the trails.

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

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)
