routing on the frame is for “down route/
pull - down swing” models.
IMPORTANT!
Please note that the maximum tightening torque on the FD clamp is 5Nm/44in/lbs.
A higher tightening torque might cause damage to the FD camp and/or frame
tube! Please also refer to the related manuals of the manufacturer of the FD.
CHAINGUIDE
On some Scale 900 (29”) Carbon models you will find a chainguide system to
support the shifting performance when using 2 chainring cranksets.
3 different mounting plates are available to match the different sizes of the outer
chainrings (39/42/44T).
Please note the max. tightening torque of 5Nm/44 in/lbs on the mounting screw of
the plate.
HEADSET OPTIONS
Scale Carbon features a tapered headset and fork steerer system to match with
semi-integrated headsets of the “50-61”mm range.
The steerers of those forks are
tapered from 1.5” to 1 1/8”.
This bigger diameter of the fork
steerer as well as on the frame
headtube helps to increase the
stiffness and handling of the bike.
