Under Seat Post Bag
Forum search yielded nothing. I am looking for a seat post tool bag which can detach easier and quicker than the standard bags out there which use clips and velcro. Something that maybe you attach a frame under the seat and the bag clips on and off that structure. I am making multiples stops of late and taking that bag off and putting it back on is a PITA. Thanks!!
Topeak makes bags with an attachment called the "fixer", and Axiom makes some with QR and some with "kwik clik" attachment, all of which i believe are more convenient than a traditional velcro attachment.
How about a nice bar bag instead ?
how big a bag do you need ..specify in cubic inches.
Well depending on how big you want, and I'll assume smaller (though I love my Carradice SQR slim at 16 liters) the SQR Carradry Glentress is 5 litres, or you could get something like the Arkel Seat Bag where you would leave the attaching points on the bike and just slip the dry bag out leaving an empty shell behind.
I use a Topeak Wedge and have the mounts for the same bag on both my road bikes so I can move one bag from bike to bike.
VauDe also has series of under-saddle bags with quick-release mechanism.
Jandd makes a nice under the seat bag that incorporates the Klickfix quick release mechanism:
I bought one to put under my Brooks saddle:
This one's cheaper:
I have one of these:
Easy off and on - press down on the tab and pull back to slide off. Their picture does not include the seat rail mount.
Great replies! Thanks. The Topeak looks like the cat's meow.
I actually ordered the Arkel bag. I read too many iffy reviews on the plastic mounting system of the Topeak bags. I can zip tie this bag pretty securely from someone not determined enough to cut it off my bike when I leave the outer shell empty.
I just received the Arkel bag in black. This thing is great! I was concerned about the size, but the dry bag is huge and the outer shell expands with an adjustable velcro strap.
