From commuting to bike packing, Timbuk2 keeps it cool.

We all know that removing weight from the back significantly enhances any cycling experience. So, with this in mind, Timbuk2 took comfort to the next level with its newly designed Hunchback Rack Trunk.

Now, this isn't a run-of-the-mill rear bag that's limited to non-bulky items and permit mounting. Instead, the Hunchback is easy to attach and detach by means of two large hook-and-loop straps. Additionally, it has a removable shoulder strap for seamless transitions from two wheels to two feet. Not only that, the Hunchback's padded and insulated main compartment has a TPU (thermoplastic polyurethane) treatment.

In layman's terms, this means that you're able to safely transport delicate items in inclement weather. So, when you're within the city's bustle, you'll be able to load up the Hunchback with brie, baguettes, and red wine for a sunset-drenched, hillside picnic. Or, if you're of the, proletariat sect, the 13 x 5.6-inch footprint and expandable roll top will happily hold a twelve'r of cans complete with ice.

The TPU coating ensures that the interior is also easy to clean post happy hour. And for even more utility, the bag includes a U-Lock pocket, multiple external stash pockets, and an aluminum bottle opener. Like all Timbuk2 products, the Hunchback Trunk Rack is covered by a lifetime guarantee.

The Timbuk2 Hunchback Rack Trunk is available in the color Black and in one size.

great bag for simple commuter

  • Familiarity:I've used it several times

This is a great bag for commuting. I needed something to take a few small items, like a pair of shoes and/or lunch to work. I ride with a backpack, but it's been getting too full with other stuff lately, so I bought a simple rear rack and this.

I only wish I would have done it earlier. Moving the weight from my back to a lower position not only makes me more comfortable, it is more efficient (closer to the ground).

The bag is very high quality, like all Timbuk2 products, and well thought out. The inside is lined with a really durable TPU. I thought from the description that it would be like the inside of a lunchbag, but it's much more durable than that. Outside is waterproof, and the rolltop is nice, especially for keeping things dry.

There's a good assortment of pockets and things to keep your small items.

Size is great. Could easily carry a pair of shoes and lunch and some other small items. During the fall/winter, I'm carrying boots, which are bulky, but still fit with a good amount of room to spare.

Very highly recommended, this is just what I was looking for. Small, simple, and not a pannier!
