GIANT Contact Switch Drop-Bar Lever Installation
Product Overview
This document provides installation instructions for the GIANT Contact Switch Drop-Bar Lever. This lever is compatible with all GIANT dropper post series, including the GIANT CONTACT SWITCH, GIANT CONTACT SWITCH CORE, and GIANT CONTACT SWITCH SL.
Important Information
CAUTION:
- The barrel adjuster is essential for proper setup. Always install one.
- Please read this manual thoroughly before beginning the installation process. Feeding the cable through the lever properly is a sensitive process; take your time and pay attention to the proper cable routing.
- Ensure the cable is not kinked or damaged during this process. The 'U shape' formation in steps E and G, along with a swift pull, is crucial. Failure to do so may result in cable fraying/kinking, requiring a new cable replacement.
Installation Steps
Step A: Cable Routing to Dropper Post
Feed the remote cable to the anchor point of your dropper post, then feed it through the housing. Continue until the end of the housing is attached to the post. Depending on the specific post model, you may need to refer to its manual for anchoring the cable.
Diagram A: Shows a bicycle cable being threaded through a housing, directed towards an anchor point on a dropper post.
Step B: Install Barrel Adjuster
Install a barrel adjuster if one is not already present. Reset the barrel adjuster and attach it onto the housing. Pull the cable tight to remove any slack.
Diagram B: Illustrates a barrel adjuster being installed onto the end of a cable housing. The cable is shown being pulled taut to remove slack.
Step C: Position and Tighten Lever
Loosely fit the remote lever to roughly 1 inch below the left-hand brake lever. Check the operation and ensure there is no interference around the remote. Tighten it to 3Nm. Do not overtighten.
Trim the short housing section to length.
Diagram C: Shows the remote lever being positioned approximately one inch below the left-hand brake lever on a handlebar. An arrow indicates tightening the lever to 3Nm, with a 'Do not overtighten' warning.
Step D: Feed Cable to Remote Hole #1
Feed the remote cable through the short housing section, then feed it through the remote hole labeled #1 on the lever assembly.
Diagram D: Depicts the remote cable being fed through a short housing section and then into the remote hole labeled #1 on the lever assembly.
Step E: Form U-Shape for Hole #2
Loosely feed the cable through the remote hole labeled #2. Use one hand to guide the cable into a 'U shape'. Note: Forming the 'U-shape' and pulling firmly is critical in this step to prevent the cable from fraying or kinking.
Diagram E: Illustrates the cable being fed through the remote hole labeled #2, with a crucial 'U shape' formation indicated for proper routing before pulling.
Step F: Swift Pull with Upper Lever
While holding the 'UPPER LEVER' in place, pull the cable in a swift action.
Diagram F: Shows the 'UPPER LEVER' being held in place while the cable is pulled with a swift action.
Step G: Form U-Shape for Hole #3
Loosely feed the cable through the remote hole labeled #3. Use one hand to guide the cable into a 'U shape'. While holding the 'UPPER LEVER' in place, pull the cable in a swift action. Note: Forming the 'U-shape' and pulling firmly is critical in this step to prevent the cable from fraying or kinking.
Diagram G: Similar to step E, this shows the cable being fed through the remote hole labeled #3. A 'U shape' is again emphasized for proper routing, followed by a swift pull of the cable while holding the 'UPPER LEVER'.
Step H: Tighten Pinch Screw and Finish
Tighten the pinch screw to 3Nm. Cut down the excess cable. Fit a cable end.
Diagram H: Shows the pinch screw being tightened to 3Nm. Excess cable is then cut, and a cable end is fitted.
Final Checks
The installation is almost ready. Adjust the barrel adjuster as needed. Test the operation of the dropper post. Once done, continue wrapping the handlebar tape as usual.
