Product Information
Full details
The Gusset Lil' Chap Chain Device is an essential upgrade for mountain bikers and gravel riders utilizing 1X drivetrains who want to eliminate the risk of chain drops. Offering a lightweight 50g profile, it provides robust chain retention through a glass-reinforced plastic upper guide and a CNC alloy bracket. While it excels at keeping your chain securely on narrow-wide chainrings, users should note that it is designed specifically for 1X setups and is not suitable for multi-chainring drivetrains.

FAQs
Can I use the Lil' Chap with a 2X drivetrain?
No, this device is specifically designed for 1X drivetrains and will not function correctly with a front derailleur or multi-ring setup.
Does this fit all seat tube sizes?
It is compatible with 31.8mm and 34.9mm seat tubes using the included shims.
How much does it weigh?
The total weight of the Gusset Lil' Chap is 50g.
Is the guide material replaceable?
The upper guide is made of durable glass-reinforced plastic designed for longevity, though you should check with your local shop for spare parts availability.
Do I need special tools for installation?
Standard metric hex keys are typically all that is required for mounting and adjustment.
Troubleshooting
Chain is rubbing against the plastic guide
Adjust the chainline position on the bracket or ensure the guide height is correctly set to 2-3mm above the chainring.
Device rotates on the seat tube
Ensure the shim is properly installed and the mounting bolts are tightened to the manufacturer's specified torque.
Pros and Cons
Pros
- Extremely lightweight design at 50g

- Easy to install and adjust
- Includes shims for multiple seat tube sizes
Cons
- Compatible only with 1X drivetrains
- Requires specific seat tube diameters

Setup, Compatibility & Care
Installation is straightforward due to the modular design. Use the provided shims to match your seat tube diameter of either 31.8mm or 34.9mm. Ensure the bracket is securely bolted to the seat tube at the recommended torque. Adjust the height of the guide so it sits approximately 2-3mm above the top of your chain when the chain is on the chainring. Regularly check the mounting bolts for tightness after the first few rides. For care, simply wipe down the plastic guide with a damp cloth to remove grit and debris that may accumulate during muddy rides, ensuring the chain remains clean and silent.
