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.What the road.cc scores mean

Mounting open tubulars and difficult clinchers is never fun, but if you're snapping levers, this odd-looking Challenge Clincher Mounting Tool makes the job a lot easier – at a price.
Most tyres are absolutely fine to mount with just my thumbs. I have, though, on occasion, needed levers for new tyres and the tightest tyres I've ever fitted snapped two levers. This tyre mounting tool presents a useful solution for such situations.
The lever works by lifting the final section of tyre onto the rim while being supported by the opposite rim bead. Mounting the Challenge Strada Open Tubular tyres that I was reviewing at the same time, I found it to be a more stable and therefore powerful method.
Using the tool is pretty easy, with the one-handed operation allowing the other hand to provide stabilisation. You do have to be careful to not pinch the inner tube, though, so that issue still exists.
I can see this tool being really useful on tubeless systems where the tyre-rim interface is rather tight. This is certainly the most rigid system for mounting tyres that I've used. That rigidity comes from the high-density synthetic polymer construction. The tool is safe to use with beaded carbon and alloy rims. I experienced no issues with damage to tyres, rims or to the tool itself.
At £15, it's much more expensive than a decent set of levers, but if you're mounting a few tubeless tyres each year then it's going to be worth it. Would I buy one? Well, since I snapped those others, my Park Tool levers have managed just fine, so... not yet. If this tool did tubulars too, then I'd definitely get one. No matter how much pre-stretching I do, they always fight back.
One final thing to consider is the size. A set of levers, even long ones, will slip into a jersey pocket or saddle bag easily. This won't, meaning you'll have issues with a roadside fix should this tool be vital for installation.
All things considered, this is a well-made tool that works, but 15 quid is a fair chunk to pay, so give consideration to your potential usage. If you struggle with tyres or mount a lot of tubeless tyres then I'd recommend it.
A well-made tool that is pretty easy to use and worth the cash for super-difficult-to-fit tyres
