Your rear brake and shifter housing should run parallel around the left side of the head tube. Run the shifter
housing and the brake housing into the individual ports at the head tube and thread them down into the
down tube toward the exit ports above the Infinity Link. The shift housing comes out of the port on the drive
side and goes immediately into the corresponding port on the swing arm. The brake housing does the same
on the non-drive side.
NOTE: Using rubbing alcohol to help the housing pass through the grommets in the frame as you thread
them.
Also, starting at the back of the bike and working forward will be necessary for some brake systems.
Caution: The failure to properly route shifter housing can cause malfunction of the shift mechanism and
unexpected shifting of gears.
The rear derailleur housing will exit the swing
arm via the port on the top of the seat stay, right
above the rear derailleur. Create a gentile curve
to the derailleur and adjust to the manufacturers
specifications.
The SB4.5 is designed to use an internally routed dropper post. The housing should be routed form the post
forward. Guide your housing through the seat tube and into the down tube use the guide tube installed in our
new frames, or use the old housing if you are replacing the line on a used bike. The line should exit the down
tube at the head tube on the drive side and curve around the head tube to the lever on the left side of the
bar. If you are mounting your lever on the right side, you would simply route that housing over to the right. If
you do route to the right we recommend placing some clear vinyl in fromt of the port to prevent cable rub.
CABLE SETUP
The SB4.5 uses internally routed full length cable housing. By using full cable housing, we have
eliminated break points in the line of your shifter housing. This allows for better overall shifting
performance by reducing the entrance of unwanted elements such as sweat and sediment.
By routing that housing internally we add to the protection from the elements and clean up the
lines of the bike. No more zip ties to snag your shorts on and no more loose housing rattling
around on your paint.
Do not remove any of the housing guide tubes that are installed in your new frame and swing
arm. They will be used to pull your housing through the frame. If you are replacing used
housing, use the old housing to pull your new housing through the frame.
If you don’t have the guide tubes or old housing you can fish the housings through the frame,
but it will be easier to use an internal cable routing tool.
REAR BRAKE AND DERAILLEUR

The rear brake housing exits the swing arm on
the inside of the chain stay and goes directly up
to the caliper. If your caliper allows, adjust the
housing attachment angle to reduce the bend in
the cable as much as possible.
