Challenge Clincher Mounting Tool



A well-made tool that is pretty easy to use and worth the cash for super-difficult-to-fit tyres

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.

What the scores mean

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

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.

  • Pros: Makes fitting difficult-to-fit tyres and tubeless systems easier, funnily enough...
  • Cons: Quite expensive compared to a good set of levers

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.

> How to fit clincher tyres

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.

I have one of these, purchased while vacationing in Tokyo. It's called a "tire bead jack" and actually made by Taiwanese tool firm Bike Hand, just rebadged by others.

If you have a folding bike with 20" (406 mm) wheels and wire-bead Schwalbe Marathon tires, they're a huge help. It also aids initial mounting of Continental 700C road bike tires, as the beads on brand-new Contis can be very tight (they loosen once they've been stretched by air pressure as mounted on a wheel).

Better to have one in the toolbox and not need it, than need it and not have it, IMHO

This looks like it might be useful. I've never failed to fit a tyre by hand, tho a Panaracer GravelKing Mud came pretty close recently, but I pay for it - the arthritis in my hands & wrists will be much worse for a day or two after a tight tyre fitting. £15 doesn't seem too high a price if it means missing a day or more of constant pain a few times a year.

Not always possible. Have some empathy with those with disabilities or who may not be as 'manly' as you.

You've clearly never tried the Conti Sport/Mavix CXP22 combo.  I can't do it with just hands.  Multiple bike shops mechanics have failed to do it with their hands.  Someone on one of my club rides decided I was just being cack at getting the tyre back on and managed to break one of their levers.


But I'm positive you're manly enough to do it without breaking a sweat.

You're clearly much too muscular in the arm department to be a cyclist

Or you could try going about it a smarter way instead of using brute force.

I've the BBB version in my workshop tool bag which is identical to the above and cheaper. A great workshop tool for tight tyres and on the bike I carry one of the VAR tyre tools which does a similar job and better than standard tyre levers for fitting tight tyres on the road.

This looks like a development of the Simson Tyre Mate that I bought a few years back.

These devices are worth their weight in gold and, being similar in size to a mini-pump, can be stashed in a jersey pocket if you're heading out on a ride.
