Ive tried 5-6 bags to hold just a tube, co2, inflator and a tire lever. Eventually they all fall off. This has a very wide strip of velco to hold it tight. Ended up buying one for each bike!
Very good so far. About 1000km on it now. Small and compact. Clam style caddy. Doesn't move once located under the seat.
I have contents-
1xTube. A Lite Tube.
1xPark I-Beam Mini tool
1x chain link
4x sticky patches
All up weight 450g
1m duct tape
I have read issues w the zipper. If you do not close the tacoclam and hold it closed, i can see how you would be able to force the zipper car and break it. Bone head move! Don't force the zipper!
Love the size and no strap around the seat post. Velcro has good grip so far. We'll see if it wears out.
5 stars for the caddy. Loses a star for the price.
