Geometry

When it comes to the experience that one gets from riding a bicycle, geometry is one of the most important factors. With this in mind, our frame design process focusses heavily on making sure that our angles are on point. SCOTT mountain bike frames are built to maximize the ultimate ratio of light weight to stiffness. The design of all of our frames is directly linked to our highly efficient hardtail- the Scale. The Scale utilizes direct junctions between elements and achieves a rather pure and simple shape. In this fashion, our frames can be built lighter than all other designs. Tubes can be built straight and simple. In terms of stiffness, triangles- i.g. seat and chain stays along with the seat tube plus the top and down tubes- are “maximized”. Both front and rear triangles are built as “largely” as possible given the intended result. Putting our damper under the top tube, the seat stays can be firmed up much better, realizing higher characteristics of stiffness. With this design, we are not forced to add a lot of Carbon material to reinforce the area around the damper, saving additional weight. More importantly, the design of our pivot points enables great suspension performance for all of our full-suspension frames. And when it comes to performance, we do not compromise.
No matter what wheel size you choose, we believe that geometry is key. That`s why we invented several additional uncompromising features to optimize your ride. Our patented TwinLoc technology offers simultaneous control of rear shock travel and damping as well as fork damping- all from a handle bar mounted lever. Three modes, fully open for the downhills, Lockout for the steep climbs, and Traction Mode for everything in between. With each of these changes comes a slight geometry change to match the specific need of the terrain. Additionally, we employ a geometry adjustment chip. By removing the shock mount chip in the linkage, flipping it to either the low or the high BB setting, you change the bottom bracket height by 7mm, which also affects the head tube angle by 0.5-0.7 degrees. No other bikes in the world allow you to change your geometry so efficiently with such a user friendly system.


Wheelsize Technology

Acceleration plays a large factor in deciding on a wheel size. Typically, a larger wheel size will accelerate at a slower rate, as having a larger diameter and rotating mass requires more energy and time to get up to speed. In this case, a 29” wheel will accelerate at a slower rate than a 27.5”. What does this mean? If you are riding technical terrain that requires brief bursts of punchy speed, then a 27.5” wheel size would be more ideal for you. If your local track has loads of sections where you can carry momentum and flow, you might want to test out a 29” wheel size.

Increased wheel size decreases the angle of attack. That means bigger wheels make obstacles seem smaller. If you ride very technical trails that have very rocky and rooty sections, you have a couple of options. Either you are a rider that likes to plow through these sections, in which case a 29er would be perfect, or you’re the type of rider that likes to get more playful, bunny hopping above, around or off obstacles, in which case a 27.5” ride would be optimal.

Wheel comparison - angle
A larger wheel rolls over objects with greater ease due to its increased diameter. The wheel literally spans a greater distance without being impeded. So a bigger wheel in general will keep you rolling over the rough stuff and will help to maintain your speed through the corners. There is a trade-off to be made here. Would you rather bash through obstacles? Or would you prefer to use said obstacles to your advantage? If the former, a 29er might be best, if the latter, check out a 27.5” ride.

Wheel comparison - rollover
Wheels with larger diameters tend to have a larger contact patch. The larger the contact patch, the better the wheel connects the rider to the trail through improved traction. Of course there are other factors that affect this such as air pressure and choice of tire, but in general, a smaller wheel standard will have slightly less traction than a larger wheel standard. Do you usually ride in wet and muddy conditions? If so, going for a 29er is a sure fire way to gain more traction.

Bigger wheels, bigger momentum- it is as simple as that. More momentum will allow you to roll through technical sections with a smaller chance of getting hung up on obstacles.
Wheel comparison - momentum
In general, there are more and longer travel options available for a 27.5” wheel standard than for a 29” wheel base standard. 29ers in general are still limited to designs that offer less than 130mm of travel in order to keep the cockpit at the correct height to maintain the intended geometry. If you want something with more travel, then you’re better off looking into a 27.5” wheel standard.
