INSTALLATION INSTRUCTIONS
1. Install the extensions in the desired position and tighten the extension fixing bolt
so they are held snugly.
2. Install the shifters (if using bar end models) as per the shifter manufacturer’s
instructions. We recommend a light coating of assembly compound on the inside
of the extension prior to installing the shifter.
3. Install the cables as per instructions from the shifter manufacturer.
4. Check the placement of the brackets and extensions then use a torque wrench to
tighten the extension clamp.

1. Carefully determine the required extension length by performing a bike fit or measuring the
existing extensions.
2. Mark the point at which you wish to make a cut.
3. We recommend checking your measurements after first marking the cut line to ensure that you do
not inadvertently cut the extensions too short.
4.Mount the cutting guide securely in a vice. Then place the extension in the guide and line up the
marked cut line with the slot in the cutting guide.
5. Using the hacksaw, make firm strokes of the blade through the guide, allowing the blade to do
the work. Do not apply excessive force to the hacksaw as you risk snapping the blade and the
possibility of injury.
6. Repeat the process for the second extension.
7. Once you have cut both extensions, use the half round file to remove any sharp edges from both
the interior and exterior faces of the extension. A deburring tool may be used on Aluminum
extensions (not Carbon).
a. For carbon a 32T or carbon specific blade is recommended. Wrap the extension with insulation
tape at the cut line to limit the risk of splintering the carbon at the blade exit point.
b. If cutting carbon, wear a breathing mask, gloves and eye protection then dispose of the dust
residue carefully. Airborne dust particles are a respiratory hazard.
c. For Aluminum an 18T blade is recommended.
