Challenge Parigi-Roubaix 700x27c

Has anyone actually measured these with a caliper? I am considering purchasing a pair but 27s seem to be the smallest size I'm finding. My largest set of tires currentl are a pair of 25c Vittoria Open Corsa SCs on the Bianchi and there's very little clearance at the chain stays - I even have to deflate the tires to get them past the brake blocks when removing wheels. That's acceptable, but of course possible tire rub is not.

Would 27s be pushing it on early 80s race bike clearances? I've heard good things about these tires, and the pair I'm considering seems like a good deal. Thanks!

I have these in both tubular and clincher versions, and on box-shaped rims they do measure right around 27mm. They're very nice tires.

Oh, and I should probably add that I'm looking at the clincher version.

Thank you for that - at least I know they won't end up being more than 27. If that's the case, they will fit the Bianchi at least. Clearance might be tight, but as long as I don't break a spoke I should be okay

Actually, I had the tubular version of these on an 80s Bertin that I liked a lot, but had very tight clearances. Of course, I broke a rear spoke climbing out of the saddle about 7 miles from home, but miraculously had a spoke wrench in my kit. I wasn't able to get the wheel true but managed to tolerate minimal brake rub (and no rear brake) and only slight chain stay rubbing to make it home. Replaced the spoke and still have those wheels, actually, though the Bertin is long gone (too tight clearances is one reason for a bike not to make the cut around here).

I bought these tubular - strongly don’t recommend. The quality control is terrible, I had to send some back with valve issues, and there are MUCH better tires for the money.

I have enjoyed quite a few of these tires and they have been on my wife's bike as well. I always measure. Most have been a small touch over 27 when installed and spread quickly (a couple days) to 29. Then they just keep growing. I scrap them when they are 31-32mm if I've not worn them out first.

When first introduced there was nothing available that compared. Current Vittoria Corsa G+ is a much better tire than the Open you are used to. A 25mm label G+ will measure right about 26 on an old 13-14mm internal width rim. On a 17-19mm internal rim they are about 27mm. Usually available from merlincycles or probikekit for about $65/pair delivered.

Well, this has been a problem for this brand.

When you get a good batch, they sing.

When you get the bad batch, they stink.

@DD I might have some for you to try before you buy. Let me check when I get home later tonight.

My favorite tire. Don't wear that we'll, but the ride is sublime. On Mavic Open Pros they measure 29mm at 90 psi. On TB 14's, 30.5. This is for the clincher. Hope this helps.

Have a pair of the 27 clinchers on Mavic Module "E" rims. 29mm. Big Donuts.
The Campagnolo Brake QR only works for me when the brakes are set pretty open to begin with.

My last experience with them is perhaps 5 years old. At that time, I found they had a wonderful ride, but they were the most difficult tires to mount when new I'd ever seen, and they were the most fragile and flat-prone tires I'd ever used.

Getting the tires on was a struggle beyond belief, requiring the use of a toe strap to hold the first-mounted section in place while I mounted the rest of the bead -- and that was just the first bead. I found that mounting the tires with tools but without a tube and leaving the tires on the rims for 2 weeks helped stretch them a bit.

In use, I never went farther than 300 miles between flats.

I'll certainly never use them again.

Reads like an Ambrosio Elite 19 rim victim to me.
The tires are "different" to mount the first time, they arrive quite folded up. The look like flat ribbons to begin with.
I had a heavy thorn resistant tube to help them take form for a while, much easier.

True - really hard to mount (even with a tire jack), but totally worth it. As far as being prone to flats, maybe I'm lucky, but I've had only two in the four pairs I've run through. The newer model has some kinda extra belt under the tread. Don't know if that helps or not. The tread compound is soft, so they wear pretty fast. I'm willing to put up with that because of the fabulous ride quality.

Let see if this helps at all.

I have the Parigi-Roubaix 700CX27mm clincher tire mounted on a Mavic MA2 rim. I use a 27 in the rear and a 25 up front. I have been riding this combination of tires and rims for about the last ten years.

The rim measures 0.805" (20.4 mm) wide at the widest point near the bead (due to the tapered side walls of rim).

The inflated 27 mm tire actually measures 1.155" wide (29.4 mm).

If you can fit these on your bike, I'd say buy them. If you can get them at a good price, even better.


ETA -
1. Although somewhat difficult to mount, I am able to roll the bead over my rims by hand - no tools required to mount them.
2. I do not get an unusual rate of flats with these tires. Maybe one every other year, probably even less than that. I think this is mostly determined by your road conditions and how careful a rider you are, not by the tire. Part of the reason is I use a wider tire in the rear is to reduce flats.

No, the rims were Mavic Open Pro and Open Sport. The tires definitely are different, just like flat ribbons as you say. This isn't the first time this subject has been raised in this forum: How the heck do you mount a Challenge Paris Roubaix!

I have the cheaper vulcanized black wall set on Open Pros. They measure out to 29 and just squeeze onto my Ciöcc frame. I’ve been pleased with them for good ride quality and durability on gravel. Mine mounted pretty easy, in fact, some folks complain about the bead blowing randomly on these. First time I mounted it, indeed it did blow out the tube, but was extra careful the next time and no problems and it he,d up well on a 90 mile gravel ride with some rough fast descents.

I also used the Strada Bianca 33’s on my Heron when you shepherded us Seattle to North Bend this summer and they worked well.

I measured the 700C X 25 mm front tire. It came out at 1.035" (26.3 mm), also mounted on an MA-2 rim.

My size experience is similar, my 27s measure 29 now with a little age.

Before they "grow", you may need a tire jack to remove/install

Here are some of the Challenge Paris-Roubaix 120tpi budget 27mm version installed with a latex inner tube on a HED Belgium Plus rim. These are new wheels for my Trek Multitrack road touring build.:




not sure if it is clear or not but the metric dial caliper shows a width of ~30.6mm. They mounted onto the HED rims with some difficulty but the use of Velox rim tape might have made the mounting more challenging. I have since that first experience with these, am now riding Challenge Criterium front/Challenge Strada rear on my everyday aluminum Flyte road bike. They also have the (Vittoria) latex tubes which require topping up and using a good tire gauge to dial in the comfiest, fastest ride. That particular wheelset uses Velocity A23 rims taped with tubeless Kaptan tape. They make the unyielding aluminum Flyte road frame that I ride, a little closer (but nowhere near) the resilient ride I get on my titanium bike with Mavic Open Pro’s and 23c TUFO Calibra tires with Vittoria latex tubes.

Hmmm, it sounds to me that I might want to stick with the Vittorias in 25c. Those tires were suggested to me years ago by @gomango and I've been very happy with their ride, ease of mounting and decent wear. Since I rotate through the four bikes I have them on, wear is the least of my issues, actually. I was looking to add some spares by trying the Challenge PRs, but from what I'm reading, they will be a Challenge to mount, and they might end up being too big for restrictions of the bikes in my fleet.

The price with shipping worked out to be about $48 per tire. When it comes to tires, I don't know why, the set number in my head I will not go over (for clinchers) is $65 per tire. I always try to find the best tire for the money, and the Vittorias have certainly fitted the bill; I normally find them for about $50 each and am happy to spend that amount.

Thanks for all the feedback so far. I haven't given up the idea yet, but I won't be buying them until I can do a test - which perhaps @gomango might be able to facilitate.

Does that only apply to the tubulars? I'm looking for clinchers, and they all seem to be made basically the same.

I appreciate the offer and that would be pretty cool to be able to try them for size and mounting before spending the coin. If you do have one I can test out, that would be awesome - thank you

I would give a vote on not giving up on Challenge tires. They are just the “open tubular” style which requires a few minor installation techniques that are not difficult to repeat without drama, once done successfully once or twice.

I assume the 27 mm Parigi-Roubaix tires you are in possession of are the more expensive 320tpi thread count cottons? I believe the “Parigi-Roubaix” name was substituted for a few years (copyright issues?) which seems to date your tires as several years old. Do you remember what you paid each for them? As far as I can tell, these tires are back to being called “Paris Roubaix” once again.

If your bike(s) have tighter clearance where 25mm is your maximum, I still would highly recommend the Challenge Criterium SC 320’s with a Vittoria latex inner tube. These only flare out to between 26-28mm width. They ”sing” when ridden at moderate tire pressures like a good set of tubulars do. You can get a super plush road ride by running 75psi front and 82-85psi rear. I weigh#195 BTW.

As far as I can tell, these tires are back to being called “Paris Roubaix” once again.

If your bike have tighter clearance where 25mm is your maximum, I still would highly recommend the Challenge Criterium SC 320’s with a Vittoria latex inner tube. These only flare out to between 26-28mm width. They ”sing” when ridden at moderate tire pressures like a food set of tubulars does. You can get a super plush road ride by running 75psi front and 82-85psi rear. I weigh#195 BTW.
I haven't bought them, so am not in possession of them yet. You see, I wanted to get some feedback from users before I dropped any money on something I might not be able to use. The biggest issue isn't so much mounting them - I can deal with a tight tire here and there, no problem. But they have to be able to fit on my bikes, and if the 27s are more like 29s or 30s, they will be too big. I'd try 23s or 25s, but currently don't see any for sale on the evil online auction site. The PR pair I found works out to just under $100 which fits my maximum outlay of $65 per tire. They look good, and the tread is similar to my Vittoria Open Corsa SCs. The pair I'm looking at has 260 TPI.

I've got about 5-10 lbs on you depending on the day of the week I like to run my clinchers at 110psi up to 125psi - I haven't had a pinch flat in forever since I began running higher pressures. Rolling resistance on the Vitts with those pressures also make them "sing". I would bet all these tires have a similar feel. I might just do a search on the Criteriums, though. What do they normally cost per tire?

Not giving up on them yet, but I may very well have to abandon the idea of that bit fatter tire and stick with what I normally run, 23s or 25s. Thanks for the great feedback!

You’re welcome!

Challenge Criterium SC 320 25mm tires are selling for $51.49 at Probikekit. I guess this isn’t a screaming great deal but they might be on sale slightly cheaper at one of the English or German on-line mail order bike shops. These might be just a bit smaller than the Parigi-Roubaix depending on your rear brake bridge/brake caliper clearance or your fork clearance. What bike are these being mounted on?

I used to to run my road bike tires at 110psi+ front and rear. I gave up on this a couple years ago and now run the lower pressures I listed (~75-80 front, ~82-90 rear) and am enjoying the heck out of the supple ride quality. I did get a couple of flats on the rear at the end of this riding season after about 2,000 miles. I ended up replacing the rear tire when it lost a thumbnail sized chunk of tread one day this past October when I lost control on some chip-seal jamming my gloved hand into my seatstay accidentally while trying to flick off some debris.

The Pro’s Closet had a small quantity of Challenge Strada 300’s for under $30 each last month but they are sold out now. This is what I replaced my rear with. I did a cold weather ride on them 2 days ago and everything runs smooth and fast - no issues.
