Altura’s Aero Post rack is something of a handful off the bike but with a substantial (3kg) payload, it’s a keenly priced and well-conceived alternative to small panniers for day riding that doesn’t spoil the clean lines or crisp handling of road/audax, cross and racier mountain bikes. However, dimensions mean it's best suited to machines with at least 15cm of exposed seatpost.
The design comprises of a shapely six-litre wedge pack fashioned from Endura 500 – basically, a rugged, water repellent 500-denier polyester that moulds around bulkier clothing, locks and other belongings. The powder coated alloy frame serves to support the load and locks into the justly revered Rixen Kaul Klick Fix bracket. This accommodates posts from 25.4 to 30.8mm diameters but check the 5mm Allen screw weekly to prevent it slipping and scratching a pretty model. Ours worked fine with carbon but a sleeve fashioned from old inner tube is a sensible precaution.
Drawing back the sturdy nylon strap reveals a capacious, padded main compartment capable of gobbling large U locks, training jacket/spare clothes, food tubes and even folding tyres. While there’s a soft padded base, it’s designed with refinement, rather than protection in mind, eliminating the infuriating jangle over rougher roads and trails. Ours passed my egg-box test with flying colours but cameras and other sensitive equipment belongs elsewhere. Two smaller zipped sections riding shotgun either side are perfect for ready access to keys, wallets, multi-tools and other nick-nacks – even when you're wearing full finger gloves.
Outside, the fetching green/black livery enjoys some excellent detailing including acres of sit-up-and-take-notice night-vision reflectives and an extremely secure rubberised LED tab. The woven polyester construction shrugs at inevitable day-to-day encounters with brickwork and fumbles with aggressive foliage – it looks new after several weeks of continual service. A sustained five-minute soaking from my garden hose hasn’t revealed any obvious weaknesses in the waterproofing while the bag scrubs up beautifully using a soft brush dipped in a bucket of warm water and mild detergent.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
"The Aero Post Pack is a neat fitting pack that provides a good load capacity without a pannier rack".
A fair and broadly accurate statement.
Tell us some more about the technical aspects of the product?
Powder coated aluminium frame, bag three compartment, six litre, 3kg capacity. Polyester based Endura 500 water repellent fabric.
Generally to a high standard.
Tell us how the product performed overall when used for its designed purpose
The Aeropost rack isn't a completely novel idea but one of the most capacious that doesn't turn handling sour. Central to the design's success is the sturdy aluminium frame that clicks neatly into the tried and tested Rixen Kaul seatpost-mounted bracket.
Common to the breed, entry/release requires a little practice before the action becomes intuitive but aboard the bike there's been no unnerving sway-even laden to the three kilo limit.
The bag itself is fashioned from Duratec 500,a hardy, water repellant nylon with three sensibly designed compartments. This has passed my garden hose test with flying colours,shrugged at brushes with brickwork, frisking from foliage and other everyday carelessness so should last a few years-even paired to an mtb/crosser.
Clever reflective detailing and the rubberised LED tab complete the package and a few minor grumbles aside, it's a great day bag for thosse wanting extra capacity without resorting to panniers, or spoiling a bike's clean lines.
Tell us what you particularly liked about the product
Build quality, detailing, nice to use and not overly obtrusive on a lightweight/minimalist machine.
Tell us what you particularly disliked about the product
Nothing, although the zips might prove a long-term weakness and it's a bit of a handful off the bike – walking round town, say – but this is something endemic to the breed.
