At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
Good scores are more common than bad, because fortunately good products are more common than bad.
The Apidura Racing Top Tube Bag is a slimline model aimed at those who want to ride fast rather than haul loads of kit. Attention to detail is excellent – and there's no reason not to use it on slower jaunts if you really wanted to...
There are two versions of the Racing Top Tube pack – one using Velcro, the other the bolt-on version we have on test. This, as the name suggests, is designed to bolt directly to the bosses on the top tube – an increasingly familiar sight on gravel bikes.
There are two sets of drillings in the bag's base, theoretically meaning it'll be compatible with all frame sizes. It comes with two 3mm stainless Allen bolts, featuring rubberised washers to isolate against shock and prevent loosening.
Curiously, given the size, capacity and weight, it also features a Velcro strap for tethering it to the stem, which I found surplus to requirements.
The bag itself is made from 'Hexalon', which is a very light yet very strong laminated nylon fabric.
Measuring 23.5x4x10cm, internal capacity is a litre and is totally open plan and spartan, save for a closed-cell foam bottom to protect phones and other sensitive electricals from vibration and bigger bumps.
It employs a flap-type closure that fixes in place securely with a powerful magnetic catch. There's no danger of it being swept open on a blustery day.
There's also a cable port up front which I found adequate, striking the right balance between accessibility and protection. For context, I tend to charge lights/action camera via dynamo USB during the day, so need to be able to feed the cable from a bar-mounted dynamo switch.
None of my framesets actually feature the bolt-on option, which might make you question why I went this rather than the Velcro route, but I was curious as to whether you could successfully mount it using a neat little adaptor kit such as Topeak's Versamount.
The answer is, you can. The Versamount is one of the most secure, paint-friendly band-on designs I've come across and the 1.2kg maximum payload more than adequate for the kind of storage involved here. It held the Apidura pack rock steady and completely free of annoying sway.
I've used it to carry a double decker USB charger, smartphone, cash in a freezer bag and a packet-fresh spare tube. It's incredibly easy to flick the flap, reach in and close again, even when riding at 20mph plus.
Careful packing helps, but the foam 'flooring' seems to play its protective part well enough too, with minimal rattle over washboard surfaces and scabby tarmac.
Hustling along on my fixed gear winter trainer these past few weeks, I've concluded it would make easy transition to road and even time trial bikes, where easily accessible and unobtrusive are key (assuming you were looking towards the Velcro or band-on routes).
The slender profile means there have been no issues with knee clearance, the sort that can often lead to a slightly curious 'knees out' pedalling style.
Given its profile and location, it's well shielded from brambles and other abrasives – no bobbling or other damage to date, and the fabric is easily wiped clean. To date, superficial spatter is dismissed with a damp cloth, though during winter I'd probably go the soft brush and sudsy bucket route while doing the bike.
Talking water... I was a little wary of directing the garden hose at the bag at close range with goodies on board, so performed said test for three minutes with the bag empty. Nothing got through – it remained bone dry inside and I've had no issues in wet, showery conditions.
Even allowing for the nice materials and touches, compared with some designs and relative to capacity, £52 seems a bit steep. It's cheaper than Restrap's Race Top Tube Bag, which is £59.99, but that is 1.5L.
Restrap's non-Race 0.8L Top Tube Bag comes in at £31.99, although it's not waterproof, while the bolt-on version is £34.99, the same price as Topeak's Fast Fuel Tri Bag, albeit with a smaller (0.6 litre) internal capacity.
The Velcro versions of the Apidura are slightly cheaper – £50 for the 1L size, £45 for the 0.7L.
There's no getting away from the fact that the Apidura Racing Bolt-On Top Tube Bag is pricey, but it is also very well made, with innovative features. Overall, I think it's very good.
Great bag with innovative design and features, but pricey

Make and model: Apidura Racing Bolt-On Top Tube Pack
Size tested: 1L
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?
Apidura says: "The Racing Bolt-On Top Tube Pack is designed for ultra-distance competition, gravel racing and the needs of time-conscious riders whose bikes have top tube bolt bosses.
'With an innovative magnetic quick-access flip-top opening, this waterproof bolt-on top tube bag is ideal for storing battery packs, mobile phones and race essentials. Constructed from an ultralight, waterproof laminate developed for Apidura, the bag fastens securely to the top tube bolt bosses common on gravel and adventure bikes, with a choice of two mounting positions to accommodate different frame sizes and geometries. The completely waterproof flip-top opening provides fast access and a clear view of the full contents of the bolt-on top tube bag, while keeping your belongings dry.
'A closed-cell foam padding structure protects your frame and electronics from damage on unsealed gravel roads and for added convenience, a protected cable port enables charging of devices on the go. Specially designed, high-contrast reflective features enhance side visibility in all light conditions.
'The race bolt-on top tube bag is a useful standalone bag for gravel riding or as part of a full Racing Series setup. For bikes without bolt-on bosses see our Racing Top Tube Pack."
My feelings are that it's a well made and designed top tube bag, but rather pricey compared with other options.

Overall, I've been very impressed with the Racing Bolt-On Top Tube Pack. The slimline design will hold essentials that you want to keep safe yet easily accessible. I've only noticed it in the positive sense and despite some initial uncertainty regarding the magnetic flap, water-resistance has not been compromised.
