Topeak trunk bag

Is awsome! I can put towels on the sides and lunch in the top part when we go to the beach. I knew this bag weird not work with the track so I purchased an accessory that my husband installed and it worked great!

I like the bag a lot. My only gripe is that it does not fit the standard rack. I had to buy an adapter and mount it on the rack. Then the slides mechanism works well. Thank you.

The bag is more!

The top peak bag is very roomy the side saddles pack a lot I appreciate the bag and ease of getting it off the bike rack, make sure you get the right bike rack is the only downfall.

Hi Tina,

Thank you for leaving a review! Glad this worked for you.

Great bag with fantastic expansion capability

This is sturdy bag with plenty of space in its most compact configuration and gives me a place for my water bottle. (I have a step through NG Pace 500, and mounting the bottle in the step through area made it too difficult to get on the bike.) The expandable panniers provide plenty of extra storage for things like a jacket or groceries with very little extra weight.
