The HMF carbon fiber Scale 20 is a XC race machine. Built with Shimano XT, Rock Shox SID, and Selle Italia SLR saddle, this is a fully capable, yet more budget concious racer.

Frame: Scale carbon, HMF-Net fibers
Suspension: Rock Shox SID RL, 100mm
Group set: Shimano XT
Brakes: Shimano XT disc
Wheels: DT Swiss XR20

LIGHTWEIGHT
The Carbon Experts at SCOTT have done it again. The redesigned Scale, at under 899 grams, and all new carbon Scale 29er, at under 949 grams, are the lightest bikes in their classes.

Using IMP carbon technology enables us to eliminate excess material needed in earlier tube-to-tube construction, saving considerab¬le weight throughout the frame.

For example, The IMP3 front triangle saves 35 grams by constructing the top, head and down tubes as a single piece.

IMP3- INTEGRATED MOLDING PROCESS
Our engineers have developed IMP3™, the newest technology applied to carbon production. The toptube, headtube and down tube are produced in a single step using a top-secret process.

Our proprietary process allows for lighter construction by removing 11% of the material from the headtube intersection while increasing strength by utilizing high modulus stressed fibers for more precise fiber placement in critical areas. To compliment the IMP™ process, our frames benefit from our Naked External Tubeset™ which eliminates the cosmetic carbon layer to shave precious grams.

STIFFNESS
The new Scale dispels the myth that a light bike cannot be stiff. Due to a targeted layup structure in high stress areas, the use of the PFBB30/PFBB92 standards, and the incorporation of a tapered head tube, SCOTT has achieved results in proportion to weight that have not previoulsy been attained.

Comparison of the old Scale vs. the new Scale
Steering area Stiffness + 10%
Bottom bracket Stiffness + 15%
Bottom bracket Stiffness + 10%

We always measure and test all our frames in our laboratories. The accrued data base has been used to validate the computer analyses, which were key in optimizing the new Scale by:
-reducing maximum material stress
-mitigating stress concentrations
-evaluating stiffness and deformation

PRESS FIT BOTTOM BRACKET
By implementing PFBB30 standards, bonded alloy pieces are no longer utilized to install threaded bottom brackets, saving 30 grams of frame weight and increase stiffness.

TUBULAR STRUCTURE
One carbon piece tubular seatstay, chainstay & dropout combined with Direct Postmount 160 to shed an additional 25 grams.
= Homogeneous structure (less material, optimized performance, less weight)

SCDS SCOTT CARBON DROPOUT SYSTEM
SCDS uses a carbon fiber dropout with a replaceable alloy hanger. A lightweight, precise and durable alloy disc brake mount improves heat distribution while braking. Carbon chain stays with integrated carbon dropout shave additional grams from the complete bike. Found on the Spark, Scale, Genius, full Addict road range.
