Axiom Charlevoix Trunk Bag
6 10

The Axiom Charlevoix is a functional rack-top bag that lacks frills, bells or whistles, but doesn't cost very much.

Rack bags like Axiom's Charlevoix are a good solution when you need to carry more than will fit in a little under-seat bag but not enough to fill a pannier. Day rides and audax are the obvious examples. A capacity of six litres is sometimes enough for utility trips around town or to work too. So how does it stack up against the traditional saddlebag, such as a Carradice Barley?

There are pros and cons. A saddlebag doesn't require a rear rack, only an SQR block (Carradice's quick-release bag carrying system), a bag support, or bag loops on the saddle. A load in a saddlebag is to some extent suspended rather than sitting on top of the rear wheel, so you won't bruise your banana (not a euphemism). But a rack bag is more aerodynamic and won't knock against the back of your legs. This Axiom one has another advantage: it's a lot cheaper.

The Charlevoix measures 34.5cm x 18cm x 15.5cm, just big enough for a loaf of bread to fit inside. There's a zipped pocket on the back that's big enough for tools and a spare tube. The main compartment has a two-sided zip running around the top, and there's a carry handle. It lacks an elastic cargo net or D-rings on the top, so there's no way to strap a waterproof jacket there. There's no LED light loop at the back either, although there are reflective patches. These things would add greatly to the bag's utility without, as far as I can see, adding to much to the cost.

The Charlevoix is made from 600 denier polyester. It's tough but not waterproof. I expected an elasticated waterproof cover in the back pocket to make up for this; there isn't one. The main compartment is well padded, with a foil-style inner face designed to keep contents cool (or warm). That will be handy for picnics and for audax riders wanting to tuck into a Snickers bar that's not a melted chocolatey mess.

Attachment to your bike's rear rack is a simple as it gets: there's a velcro strap at each corner. This has the advantage of being compatible with almost any rack, and actually worked okay. I found the bag stable and secure at all times. It feels a bit fiddly and primitive compared to Topeak's QuickTrack system, where the bag slides on and clips into place in less time than it took you to read that last phrase. Then again, a QuickTrack bag locks you in to using one of Topeak's racks too, so you'll end up shelling out a fair bit more for that slick, systemised convenience.

On the whole, the Axiom Charlevoix exceeded my expectations. It's simple but it works and it costs buttons. It's better than using a single pannier if you've got a small load, as the weight is carried centrally. I wouldn't swap it for my Carradice Barley, and if I were in the market for a rack bag I'd pay more for extra features and weather resistance; Axiom's own Randonee Trunk is a waterproof rack bag for just £33. But if you're on a really tight budget, the Axiom Charlevoix is worth considering.
