Large Bicycle Seat Bag
This hand-finished, hand-stitched thick and stiff leather bag adds classy storage to a bicycle with a buckle enclosure, backed up with an additional leather twine that wraps around the seat stem.
The dimensions are 5" x 3" x 2.5" — big enough a small set of tools to keep things running smoothly, not to mention your keys and ID.
While this might not be a great choice on your road bike, if you have an old cruiser you're looking to upgrade, this is a great way to do it for just $72.
