Apidura Racing Long Top Tube Pack 2L— Specs & Analysis
Manufacturer specifications, compared against every other top tube & feed bags in our database. We do not test gear in the field — we measure, verify, and compare.
Forty-four centimetres long and only 4.6cm wide — this is a completely different animal from a stem bag. Two liters of storage running most of the length of your top tube, in the narrowest profile in the category.
The long top tube pack is one of the genuinely good ideas to come out of ultra-distance racing, and once you understand the geometry it's obvious.
A conventional top tube bag is short and tall, which puts volume where your knees are. A long top tube pack is the opposite: 43.9cm long, 9.9cm tall, 4.6cm wide. It runs almost the full top tube, stays low, and is narrower than every top tube bag in our database except its own Backcountry sibling — the field median is 8cm, and this is 4.6cm.
That width figure is the one that matters. Four point six centimetres is narrow enough that most riders' legs never contact it at all, which means you can carry 2 liters in the most accessible position on the bike without the knee-strike penalty that normally comes with it.
The catch is the frame. A 43.9cm bag needs 43.9cm of clear top tube, and on small frames — or any frame with a lot of standover-driven slope — you simply don't have it. This is a bag that fits medium and large frames and leaves small-frame riders out, which is a pattern that shows up over and over in bikepacking gear.
210g and $115. The weight is high for 2 liters and the reason is the length: a long bag needs structure to stop it collapsing in the middle.
One honesty note — the retailer listing we sourced this from publishes dimensions and weight but doesn't state a waterproof rating, so we're not claiming one.
Who Is the Apidura Racing Long Top Tube Pack 2L Best For?
Medium and large frame riders who want real top tube volume without touching it with their knees. If that describes your riding style, the Racing Long Top Tube Pack 2L should be at the top of your shortlist. It sits in the Top Tube & Feed Bags category alongside 12other products we've reviewed.
How It Compares

The price-to-weight ratio comes in at $55 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 Racing Long Top Tube Pack 2Lyet. 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 13 top tube & feed bags we hold published specs for.
At 210g the Racing Long Top Tube Pack 2L is the heaviest in the category we track, against a category median of 80g.
At $115 it undercuts 0 of 12 of them, against a median of $55. That works out at $55 per 100g — below the $66 median for top tube & feed 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.
