SCOTT Unisex Gambler 920 Mountain Bike

GAMBLER INTEGRATED BASHGUARD AND CHAIN DEVICE
It seems like it shouldn't make a huge difference on the bike, but it turns out it does. We even joke saying that it dictated the design of the entire bike. Why make this a proprietary piece? Chain devices are normally made to work with many different bikes and are therefore compromised. We only need to make it work for this one frame and a specific range of chainring sizes, so it can be easier to setup, better performing, lighter and allows us to gain some advantages on the frame construction, further reducing weight and increasing reliability/durability.

Historically, designing around a chain guide / bash guard was akin to designing around a front mech – not ideal. They require a heavy, in molded alloy mount in the frame that can bend under impact, and leaves threads in the frame that can be damaged. These would restrict the frames main pivot width and chain stay shape. In addition, the chain guide and bash guard were connected by a backplate, further increasing weight.

With our design, we no longer have in-molded alloy mount, nor do we have threads in the frame. More importantly, we're able to design a wider main pivot, making for a stiffer connection and better bearing life. We've been able to optimize our chain stay shape, helping us to better maintain stiffness and strength. It is easier to set up and adjust and lighter.

We use built in rubber shock absorbers with the bashguard, reducing further the potential for frame damage. Finally, as the bashguard and chain guide are separate pieces, should either get damaged, you don't need to replace the entire system, just the piece itself. 

ONE FRAME, TWO WHEEL SIZES
With our mountain bikes, we try to achieve ultimate versatility. These specific models can switch from 27.5" to 29" or from 24" to 26" 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. 

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 fibers 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 modeling, 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 sacrificing the stiffness, comfort or impact resistance. The entire range benefitted from our Evo-Lap technology.

GAMBLER ADJUSTABILITY
Our downhill bikes have always pushed the boundaries of adjustability. Both a rider and a bike need to be able to adapt to tracks, weather conditions and choice of shock (air or coil.) The new Gambler allows you to switch between wheelsizes without changing any other components on the bike.

Chain stay length can also be adjusted, independent of wheelsize choice. Short with 29", sure thing. Long with 27.5? Yep, that too. The Gambler also comes with spare angled headset cups, so that you can adjust head angle relative to wheelsize, fork choice etc.

We also have a 4-way chip to allow not only bottom bracket height adjustment relative to wheelsize, but more importantly for geometry/kinematic tweaks depending on tracks, shocks or rider preference. We want the bike to be optimizable for each shock and rider given the track.

All this adjustment allows us to focus on balance. And by balance, we mean on the perfect combinations to find traction. Geometry and shock curve options help get a rider's center of mass in the perfect spot between the wheels for optimum levels of balance and traction. However, as race tracks change, this balance point changes, and not all bikes can change with it – we wanted to be able to do so.

For instance, a bike with geometry for a steep track will roll slowly and push wide in turns on a flatter track, whereas a bike set up for flatter tracks will make it difficult for a rider to keep their center of gravity far enough back for steep tracks.
