Full details

The Topeak Fixer F77 QuickClick Mount is the ideal solution for cyclists looking to streamline their gear setup by providing a dedicated attachment point on their seat post for Topeak bags and water bottle cages.

FAQs

Will this fit an aero seat post?

No, the Fixer F77 is designed specifically for round seat posts.

Can I use this for a heavy battery pack?

It is intended for standard cycling accessories like bags and water bottles; avoid mounting excessively heavy items that exceed the load capacity of standard wedge bags.

Is this mount compatible with non-Topeak bags?

The QuickClick system is proprietary to Topeak. It is recommended to use only Topeak QuickClick-compatible accessories.

Do I need tools to install it?

Yes, standard hex keys are required to tighten the mounting bolts to the seat post.

What is the maximum seat post diameter?

The mount is compatible with seat posts up to 31.8 mm in diameter.

Troubleshooting

Mount slips down the seat post during use.

Clean the seat post surface to remove oil or residue and ensure the mounting bolts are tightened to the manufacturer's recommended torque.

QuickClick accessory is difficult to slide into the mount.

Check the rail tracks of the accessory for debris and ensure the mount angle is adjusted so the bag sits level.

Setup, Compatibility & Care

Installation of the Fixer F77 is straightforward. Loosen the clamp bolts, position the mount on the seat post at the desired height, and tighten the bolts evenly to ensure a secure fit. Ensure the contact area on your seat post is clean of debris or grit before tightening to prevent slipping.

Compatibility: This mount is strictly for round seat posts measuring 25.4 mm to 31.8 mm. Always verify your seat post diameter before installation.

Care: Periodically check the mounting bolts to ensure they remain snug, as road vibrations can cause hardware to loosen over time. Clean the nylon body with a soft cloth and mild soap to remove road grime or salt.
