Topeak Fixer 7 DynaPack Mount – Quick-Release Seatpost Clamp for Topeak DynaPack Bags | Adjustable Fit, Secure Attachment, Durable Construction, Easy Install

I have three bikes and use one dyna pack between them.

Las baterías nos duran tanto no es tan liviano como se sugiere

This entire bag setup is quite outstanding for those looking for something to attach to your seat pole. Easy release and sturdy. I have 2 sizes.

I use this clamp on my spare bike to hold the large Topeak Dyna Pack. It works perfectly except you must be careful when transferring from one bike to the another not to put your finger in the hole on bottom or you will pinch your finger. Other than that it is an excellent product as is the Topeak Dyna Pack.

Exactly what I expected. Same as the clamp that comes with the packs of course. I got it to mount on a second bike.

Well the first one broke, so you will have to earn those stars back the hard way

As far as bike packs go the dyna pack is pretty handy for my heavy chain, and the quick release system is sturdy, easier to use than the rack track system.

It fits and enables me to switch the Dyna PAck between bikes easily.
