How often should I clean the dropper post?
It's recommended to clean the visible stanchion after most rides, especially if you ride in wet or dusty conditions, to maintain smooth operation and longevity.
What maintenance does the sealed cartridge system require?
The sealed cartridge is designed to be low-maintenance. Regular cleaning of the stanchion and occasional lubrication are usually sufficient. For internal issues, professional service may be required.
Can I install this dropper post myself?
Basic installation involves cable routing and connection, which can be done with common bike tools. However, if you are uncomfortable with bike mechanics, it is advisable to have it installed by a qualified bike mechanic.
What seat tube diameters does the 900i come in?

Does the 900i come with a remote lever?
This guide pertains to the dropper post itself. The remote lever is typically sold separately or as part of a kit, depending on the retailer. Ensure you have a compatible lever for operation.
Troubleshooting
Dropper post is slow to return or feels sticky.
Clean the stanchion with a damp cloth and apply suspension lubricant. Check cable tension and ensure the cable is clean and not binding.
Dropper post does not extend fully.
Verify cable tension. Ensure there are no obstructions in the seat tube. Check if the post is reaching its maximum extension limit.
Dropper post sinks under load.
This could indicate an issue with the sealed cartridge. Check cable tension first. If the problem persists, the cartridge may need service or replacement. Consult the manufacturer's support.
Dropper lever is stiff or difficult to activate.
Inspect the cable and housing for dirt, kinks, or damage. Lubricate the cable. Ensure the lever is properly aligned and not obstructed.
