SCOTT Ransom 920 Bike

Our integrated chain guide was developed in collaboration with the SCOTT SRAM MTB Racing Team. 

The idea behind was to create a reliable component that helps to avoid dropping chains but that was light, versatile and integrated in the design of the frame. The new Spark chain guide weighs just 23 grams and is easy to assemble thanks to the smart assembly system and can accommodate chain rings from 30 to 36 teeth.

With our mountain bikes, we try to achieve ultimate versatility. These specific models can switch from 27.5" to 29" wheels with nothing more than the flip of a chip. No need to change the fork, all you need to do is flip a shock mount chip, change your wheels and off you go. The flip chip allows us to maintain a similar BB height when switching from one wheel size to the other which is key to keeping handling similar for both wheel sizes. With 27.5" wheels, you can run either 2.5", 2.6" or 2.8" tires. For the 29er, anywhere from 2.4"-2.6" is good to go.  

We have adopted the new Metric shock sizing standards with a Trunnion mount. Since the shock body now extends between the two lower mounting bolts, our suspension partners have more design space. This means the shock has more stroke for the same eye to eye length. Stroke on the 165mm eye to eye shock has increased from 38mm to 40/45mm.The Trunnion standard also offers structural gains. The shorter shock enables us to build a very compact frame and shock package, which integrates tightly to the seat tube. We managed to have a very tiny yet stiff linkage-lighter than ever. Thanks to the Trunnion mount construction, stand over height on the new Spark is very low. We are still able to realize a super compact full suspension frame and provide the ability to mount both a small and big water bottle.

The Spark family maintains the 165mm eye-to-eye shock length of the previous Spark 900 (our shortest shock), but realises up to 7mm more shock stroke. All Spark RC and most Spark and Spark Plus bikes utilize the FOX Nude shock, specially made for SCOTT:

-165mm Metric Trunnion shock

-40mm (100mm travel RC Spark line-up) vs. 38mm (old Spark)

-45mm (120mm travel Spark line-up)

By turning the Trunnion shock upside-down, we can fully integrate it into the frame which results in several benefits.Since the Trunnion mount is the same width as the down tube and mainpivot, we can have a very clean frame design in this critical area. The lack of tight transitions and small details allows for an efficient, continuous carbon structure. Carbon material added to reinforce the shock mount also stiffens the connection between the down tube, main pivot and bottom bracket, a key stiffness path.

The flipped shock also lowers the frame’s center of gravity helping to give a more planted feel when riding. Unsprung mass is reduced since it is the lighter part of the shock, connected to the linkage, not the heavier body which must move during an impact – the suspension system can react faster.Our TwinLoc remote cable can be routed cleanly into the down tube.

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 pedaling 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 pedaling 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. 

When designing the Ransom, speed was a topic that was always at the forefront of discussion. Naturally, the geometry of the bike was selected to accompany the type of riding it is intended for. With 170mm of travel, this unique 29er has a geometry that will get you to the top comfortably and then back down faster than ever before. Long, slack and stable at speed, this rig can tame any descent. However, we didn't want to cut any corners with regards to seat angle or position. Where we live, big days involve plenty of climbing, and we think it's important that climbs can be as fun as the downs – proper climbing position is essential to that. 

Protecting the Ransom's frame was an integral part of the project. We've integrated a clever DT protector under the BB and along the downtube, and have also implemented a newly developed, noise-silencing Chainstay/seatstay protector. A quiet ride is a fast ride. 

Our suspension kinematic brings perfect balance and control to the platform. Using our Virtual Four Link design, we have honed our suspension feel, pedaling and braking response to work with maximum efficiency and in harmony with our TwinLoc Suspension System. Our kinematic suspension curve gives supple small bump sensitivity and therefore exceptional traction characteristics, perfect support in the mid-stroke and a controlled deep stroke for predictable and comfortable bottom outs. Specific pivot placements ensures efficient pedaling that drives the bike forwards like a startled greyhound and neutral braking that strikes a perfect balance between rider comfort and control, chassis stability and rear wheel traction. From the XC racer, to the downhill enthusiast, the kinematic brings improvements and advantages in all areas and gives a solid fundamental basis for a bike for all riders and all conditions.
