The Tailrider holds more than you might think since it expands quite a bit. But it remains one of the smaller trunk bags. If you travel light, it's right. If you need to carry every tool known to man, a half-ton of spare parts, plus food and extra clothes "just in case", skip it and get a steamer trunk.

I fit a multi-tool, tire levers, tube, master link, glasses, keys, camera, flash drive, U-lock, two apples, two oranges, two sandwiches, some granola bars, and work shirt and jeans. That fills it. If I take more, the jeans ride outside on top under the straps.
