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.

This BTwin seat pack is great. Simple and swappable and just the right size for the things you'd normally put in it. I wholeheartedly recommend it.

At a penny under eight quid you're probably not expecting the earth, but the Comp 0.4l Seat Post Bike Bag (another snappy name, chaps) has everything you need. It's a semi-rigid construction with a good quality zip that goes all the way round. There are reflective patches on all sides, and a light loop too. Inside there's enough space for a tube, levers, a tool and a puncture kit.

The best thing about this pack though is the mount. It's sprung, so you just push the two halves in, slip it between the rails and let go. It's stayed put on every ride on a range of bikes, and it doesn't catch my thighs. And if it doesn't catch mine, yours are probably safe.

Taking it off takes about one second, so switching it between bikes is the simplest thing ever and you can take it off when doing repairs on the side of the road too, which is more of a bonus than you might imagine. The design means it'll fit any round-railed saddle. If you have special needs with regards to your rails, you're out of luck. Otherwise, happy days. The first time I fitted it, I fitted it the wrong way round - the mount is sort of counter-intuitive. Once you've worked that out though, it works perfectly on every saddle I've tried, which is a few.

There's literally nothing not to like about it. The mount (hard plastic) has pulled away from the semi rigid case a little bit, so you can see underneath the middle of it, but the rivets holding the two bits together are still tight as new, and it doesn't look in any danger of failing; it's no different from a bunch of other seatpacks I've used in that regard.

Given that it has a 2-year guarantee the worst case scenario is that you have to buy a new one 2 years down the line, so that's an outlay of £4 a year. For the money, I simply can't find fault with it.

Go and buy one. I would say buy two, but it's so easy to swap that there's just no need.

Verdict

Perfect small budget saddlebag
