    Why do people still think Challenge make good tires?

    Their quality is simple terrible and bordering on unsafe. They're somehow difficult to get onto a rim and yet blow off when used. #neveragain

    The answer is to use a Kool Stop Bead Jack - but the real question is, what happens if you get a flat out in the wild and can't get the tire back on?

    My solution is to go with different tires. Challenge seems to have... challenges with QC.

    Their tubulars seems safe if not a bit fragile in my experience. Their clinchers looks like safety hazard based on all reports I saw on the internet and I wouldn't even consider a tubeless tire from them.

    This in a nutshell.

    1) Kool-Stop Bead Jack conquers all.

    2) Challenge tyres are shite.

    In recent past I've had some terrible Challenge CX tires.
    It seems things have changed. The Strada Bianca Pro in a 700X30c, for instance, is incredible. I've run thru two sets on my tandem. Like I said before they are so supple that it did make for some interesting times convincing them to install. The "issue" with this tire is that the casing and kevlar (?) bead are so supple that it is like convincing a fresh squid to tie into a knot. What I have resorted to both times is to use a old wheel to mount them using a tube and allowing the tires to sit on the rim for a few days. Several inflate/deflate cycles convinces them into a round shape. From my perspective you can see that the bead literally lies in the same plane as the sidewalls when new. In order to get these to install you have to patiently chase the entire bead centimeter by centimeter into the rims mating groove and buddy that's close to impossible. Thus a old wheel, warm the tires and soap...let them sit for a few days. I have pre-treated my spare as well.

    They are a ton of trouble but I really really like these (gag) clinchers.

    Maybe I'm stubborn or am mollified by past experience with tubulars?

    You should be paid by Challenge for the work and not have to pay for their products.

    I've used only Challenge brand tires for maybe 14 years now because Alex and Co. have sponsored my team that long. I've never had any issues with tread peeling back, or tubulars that didn't hold air, or nuthin'.

    And when I quit road (racing) I started to use my cx bicycle 24/7, and with Chicanes on them (24/7) during the week for my pavement rides. They were once called Grifo XS if I recall correctly.

    Now that I've quit racing cx and wanted to pull down a road frame once more, I thought hmm road tires. So I've been happily riding Paris Roubaix 27mm Open Tubulars for a month, and wanted to try the 30mm sizes. So I have one tire that I gave up wrestling with on Sunday, and asked for tips. I finally installed it on a 20mm width rim wheel yesterday though haven't ridden it. The wheel I was using on the weekend was a new model Cole/Richard Sachs CF clincher with a 23mm width (and 30mm height). I suspect the extra width hurt my chances. Mind you, I didn't spend an eternity trying to mount it. But I stopped after several tries.

    I like Challenge tires. Still do.

    I don't have any tips beyond what has already been offered here. I personally had a really tough time mounting these tires on Belgium+ rims. I think the first tire required close to an hour of struggling.
    The tires ride do really nicely. That said,it kind of creeps me out to think of a flat in the middle of nowhere.

    An FYI I've never (ever) had an issue with a tight tire being hard to handle when if the time comes to replace a tube. It's only that initial mounting, when at all.

    This was my experience too, with a pair of Parigi-Roubaix tires on Mrs. Aitch's bike. My go-to for bead wrassling is Windex or the Windex bottle refilled with dish soap and water. A tire lever that's made of steel (really) like the Eldi shown below or Park TL-5's.



    I wrassled them on, overpressured them at 100+ psi overnight and let them think about it. They came around (and became round) and have behaved themselves ever since.

    no real experience with the tire in question but agree that it is probably worse on the initial install than subsequent repair. I will also say that the bead jack is a real hand saver when needed. I don't have one for the house but we use one at the shop. Only rarely, but when needed, it works

    bead jack, soapy water. if you want toestrap/zip tie one side of the bead so it cant shift and work in on the other side

    if that fails stick the rim on the lip of a garbage can so you can get your whole bodyweight on there

    road tires are tight, but nothing is as tight as a dh casing tire with a cushcore
