At 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.

The Restrap Race Top Tube Bag is a large, stable bag with innovative fixings that should attach to any bike. The zip cover is going to divide opinion, but apart from that, it's a cracker.

Yorkshire's Restrap has been churning out made-in-the-UK bikepacking and luggage kit for a good few years now, but the company isn't resting on its successful, chunkily-stitched laurels. In the new Race Top Tube Bag, it has added some genuinely useful features to make this staple luggage item a long-distance winner.

Firstly, the size: at 1.5L this is possibly the largest top tube bag on the market. Extending way past halfway along the top tube, even on an XL frame, at 37cm this is one loooong bag. Add in the 10cm height and 4cm width, and you can fit a lot of kit inside.

The biggest challenge with top tube bags is vertical stability. There's been a plethora of solutions here, usually variations on Velcro straps that go around and underneath the stem. Restrap has come up with a stiff fabric collar that is held in place by a loop of thin bungee cord, secured by a plastic hook on the opposite side.

Unlike Velcro, the bungee loop acts as a self-tensioner, ensuring that no matter where the stem turns, or what you add or remove from the bag that changes its shape or stress on the sidewalls, the bag remains upright and taut. It fits any stem setup, even very low stack options which are usually difficult for top tube bags to handle.

The Race Top Tube bag is held in place primarily by a really wide Velcro strap set 90mm from the front, and at the rear by a thin 'Hypalon' strap that slides through one of three positions on a ladder strap sewn into the bottom rear outside of the bag. The strap has a simple yet totally secure plastic snap buckle, and can be arranged so the excess strap sits upright flush with the bag side. Both straps will accommodate really wide top tubes, so you should have no issues there. Hypalon is a special kind of tough, fray-proof yet malleable rubber from the marine industry – so perfect for binding stuff to bike frames in a non-slip, non-scuff manner.

Adding and removing the bag between bikes in a replicable fashion was literally a few seconds' work. So if you were concerned about it being pilfered outside a shop or cafe, fear not – just take it along.

The internal lining is a nice orange, making finding small things easier. The sides are reinforced with thin plastic, aiding the shape retention and minimising the chance of knee rub. With no internal divider to add strength this was an initial concern given the length, but I was able to stuff inner tubes, tools, muesli bars and even a light windshell aboard with no notable bulging. What you see inside are the bound seams – a layer of nylon webbing stitched over the panel fabrics for reinforcing.

So far, so secure storage. Which brings us to the bag's Marmite feature: the 'unique Hypalon zip cover'. This is a long flap that can be used to pull the zip open, with the usual pull-tag to close. The flap is secured to the zip itself in manufacture – if you wanted to remove it you'd have to get agricultural and bend the zip to disconnect it, but I'd suggest you don't.

The zip itself looks waterproof, and the flap overlaps it on both sides by about 10mm. Under the Garden Hose Of Doom (Mist Setting) for 10 minutes, there was a veritable river of water running down the length of the flap, and (as would be expected) none underneath. Upon opening, the test towel inside was dry.

So... is the cover really necessary? Adding weight, something to break, get caught in the wind, annoy you... In short, yes. Using a pair of pliers I undid the flap, thereby exposing the zip and its seams either side to the simulated shower, and water did indeed make its way inside. As the zip and the 'X21' fabric that it's sewn into are waterproof, the ingress was via the seams of the bag; they're reinforced internally and very strong, but not waterproof.

As with Restrap's Race Frame Bag, the trade-off here is for strength, longevity and lower cost over 100 per cent waterproofing.

Riding about for a few months, occasionally in high winds, the zip flap was surprisingly stable – I can only recall a few occasions where I felt the need to pull it forward again a little to make it lie flat. I was concerned about knee rub but that didn't happen, even out of the saddle – of course, your mileage may vary depending on your/your bike's dimensions. The zip was easy to operate even through multiple glove layers, and there was nothing about its use that was in any way untoward.

Value and conclusion

Now, £60 for a top tube bag is right up there in the price stakes, but if you want the extra space then you're short on choice. Apidura does a 1L bag (not waterproof) for £47, and Alpkit does a few but its 1.5L Fuel Pod isn't currently available; 1L is the max, for £34.99.

The Restrap Race Top Tube Bag screams 'adventure' in big black ALL CAPS letters. Paired with their other Race series bags, it maxes out your storage and does so in a stable, easily fitted way. Recognising the balance between cost, strength, mostly-waterproofness, and Made-Locally-ness, all round it's a class bit of kit.
