Where to Buy
Apidura Backcountry Frame Pack 1L— Specs & Analysis
Manufacturer specifications, compared against every other frame bags in our database. We do not test gear in the field — we measure, verify, and compare.
A 1-liter partial frame pack that weighs 100 grams — 22.1cm long, 10.4cm tall, and small enough to fit triangles that defeat everything else. If you ride a small frame and every frame bag on the market says no, start here.
Small-frame riders lose more to bikepacking gear than anyone else, and frame bags are where it hurts most. A full-triangle frame bag runs 55 to 58cm long and 25 to 26cm tall. A 50cm frame's triangle often can't take anything close to that, and the standard advice — "get a custom bag" — means four to six weeks and a lot of money.
This is 22.1 x 10.4cm. That's under half the length and under half the height of a full-triangle bag, and it's the smallest triangle-mounted bag we hold dimensions for. If you've measured your triangle and come away disappointed, this is a bag that will probably fit it.
One liter isn't a lot, and there's no pretending otherwise. It's a tube, a tool, a pump head and a bar. But one liter in the frame is worth more than two liters hanging off the back, because frame volume doesn't sway, doesn't affect steering, and sits at the bike's centre of mass.
100 grams and 5.8cm wide — under the 7.5cm category median, so it won't crowd your legs.
$81. It is worth being clear about what this is not: it isn't the Backcountry Top Tube Pack, which is a different bag that we hold separately. This one mounts in the triangle.
Who Is the Apidura Backcountry Frame Pack 1L Best For?
Small-frame riders who've been told nothing fits their triangle. If that describes your riding style, the Backcountry Frame Pack 1L should be at the top of your shortlist. It sits in the Frame Bags category alongside 19other products we've reviewed.
How It Compares
At 100g and $81, the Backcountry Frame Pack 1L is the lightest option in this category. The most budget-friendly option is the Moosetreks Full Frame Bag at $60.
The price-to-weight ratio comes in at $81 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.

The Bottom Line
We haven't scored the Apidura Backcountry Frame Pack 1Lyet. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement and we don't hand one out until someone has a basis for it.
Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.
How it compares
Against the 20 frame bags we hold published specs for.
At 100g the Backcountry Frame Pack 1L is the lightest in the category we track, against a category median of 198g.
At $81 it undercuts 13 of 19 of them, against a median of $130. That works out at $81 per 100g — above the $68 median for frame bags.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
