Good quality handmade tyre with a supple ride and good grip.

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.

Good scores are more common than bad, because fortunately good products are more common than bad.

One of a select few tyres still available in a gumwall finish, the Challenge Criterium open tubular is a great choice for a retro bike, but the quality and feel of the tyre give it a broad appeal.

Open tubular? Similar to Vittoria's Open Corsa tyres, the Criterium uses the same hand-made carcass as Challenge's tubular tryes, but instead of sewing it up they add a bead to make it into a clincher. The carcass is cotton rather than nylon, at 320TPI (threads per inch) which is much higher than most clincher tyres (60-150TPI is normal). Challenge claim that this makes the tyre much more supple. Another big difference is that the tread is hand-glued onto the carcass, rather than the whole tyre being vulcanised, which affects the properties of the rubber.

Certainly the Criterium is much more supple than a standard clincher, you can easily fold the carcass and fresh out of the box it lies completely flat. Getting it on the bike first time around is a bit of a faff but once on and inflated it takes on a much more tyre-like shape the next time you have to pull it off.

Ride feel, and the grip from the file-pattern tread, is very good. The Criterium feels supple and there's plenty of traction when you lean the bike over, even in the wet.

Challenge don't claim the Criterium open tubular is massively puncture resistant and that would tally with what I've found, but it's no worse than other race-oriented rubber.

Challenge claim a 200g weight; ours weighed in at 220g each which is fairly light but not as light as they claim. Given that these tyres are hand-made you'd expect a little more variation.

Overall the Criterium open tubular impressed. The quality and ride characteristics are similar to the Vittoria Open Corsa Evo CX which is the same kind of money and of similar construction.

At £50, it's not cheap, though. You can have them online for about £40 and sometimes cheaper, which still isn't a bargain considering there are some very good tyres out there for a fair bit less, but you might want to treat yourself and you won't be disappointed with the ride. If you don't want gumwalls the Criterium is available in black too, and also all-white.
