STEM CABLE GUIDE -
The front brake cable enters the head tube cable guide in the non-drive side forward
hole. The rear brake cable enters the head tube cable guide in the drive side forward hole.
HANDLEBAR HOUSING
- The brake housing loop lengths between the handlebar and the stem guide
should be determined after the handlebar stem and aero extensions positions are set. When cutting the
housing between the extensions and the guide, the loop should be a smooth curve enabling necessary
handlebar movement and smooth cable action inside (i.e. no bending turns which will negatively influence
brake cable movement).
FLEXIBLE HOUSING LENGTHS
- The flexible brake housing inside the head tube for the front brake is a
specific length for each frame size. The cut lengths for the frame sizes are given in the table. This flexible
housing extends from the bottom of the head tube cable guide through the inner head tube cable guide
to the 90° aluminum noodle.
The flexible housing for the rear brake which exits the bottom bracket cable guide is 62mm for all frame
sizes. The teflon tubing length is 80mm for all sizes. It should be trimmed as noted in the rear brake
illustrations.
TEFLON TUBING
- A section of 4mm tubing is used inside the brake cable flexible housing. This teflon
tube is flanged at the top to prevent the tubing from sliding out of the housing with cable movement. The
tubing overall length extends to just beyond the 90° aluminum noodle. Terminating the tubing before the
end of the noodle will create unwanted cable drag. Trim the tubing cleanly to avoid creating rough edges.
Cable lubricant is applied inside the teflon tubing to reduce cable friction. Add a very small amount of
cable lubricant inside the tube when changing it.
CANTI BOSSES
- Apply Loctite 271. Tighten to 8.0 Nm, (70 InLbs).
