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.

Topeak's Tubular Barbag Slim sits well on the handlebar, carries a useful amount of stuff, and keeps the worst of the weather out. It's competitive in terms of price, too.

This Slim version of Topeak's Tubular Barbag is 1.5 litres in volume, so takes up little room out front of the handlebar, yet it's roomy enough to carry your essentials like tools, a mini-pump and snacks. You could even stuff a waterproof jacket in there, although with not much else.

At 190mm in length it'll fit pretty much any handlebar, and with a 100mm diameter it's not bulky either.

It's held in place via two Velcro straps which Topeak says can accommodate up to 56mm diameter bars, and to minimise sway it also comes with a reflective elastic cord that can be secured around the head tube.

Sway isn't really an issue, though, even when loaded up to its 1.5kg maximum, and one thing that I do like is that the bag maintains its tubular shape even when empty. That makes it easy to get things in and out of on the fly, plus it looks better.

For access there is a large zip that runs from one side to the other, with a tab that makes opening it easy when wearing gloves.

Another neat addition is the row of loops along the front that you can hang a light from, or other stuff.

The bag is made of 600D polyester, which is water repellent rather than waterproof, so in very wet weather you'll need to place anything that needs to be kept completely dry inside some kind of dry bag. That, though, is probably the only chink in the bag's armour. The material is tough and the whole bag is well made throughout.

Colour options are black or this green.

Price-wise, it's cheaper than the similarly sized Restrap Canister Bag (£49.99), although that is handmade in the UK.

It's £3 less than the Zefal Z Adventure F2 Front Bag, but that's actually 2.5 litres, although it doesn't really look that much bigger. The Zefal is also waterproof, but Bryn criticised the small zip opening.

The Cycology Secret Garden Aqua Handlebar Bag looks to be slightly better value at £35, especially considering it's 2.4 litres in volume, and it comes with extras like a side pocket.


Overall, although there are bigger bags available for similar money, I think the design of the Topeak makes good use of the volume on offer. I think it's a well-designed bag too, and made to a high quality, with the biggest plus being that it retains its shape, making it easy to access when riding.

The handmade Restrap Canister bag is £13 more, but it's in the same ballpark as many others, such as those from Cycology or Zefal mentioned in the review, although those are more generous in terms of overall volume.

After first throwing his leg over a race bike back in 2000, Stu's ridden more than 170,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him, he still likes to smash the pedals rather than take things easy.
