Surprised to see "Made in Romania" on the box. I'm sure I saw Campag stating they use the best Italian carbon fibre or are the components put together in Romania?

Does Romania have specialist wheel building factorys? I think a lot of Mavics are built there too.


My understanding is Campagnolo have a wholly owned factory in Romania, in part I imagine to save labour costs, and I guess it builds capacity and flexibility in their operating model also. Remember it's just a short drive east from where Campagnolo are based, and of course in the EU

Finally got out on my BU35's with glued ContiComps25's.

Initially I didn't really appreciate any real difference from my last set of wheels (24mm Vision TC24 with Vittoria CX tubs). I eventually realised towards the end of the ride I was riding 2 or 3 gears up. Then I checked and saw I was climbing shorter, steady climbs on the big ring rather than clicking into the small ring.

I had a bit of fun trying accelerations whilst going uphill. I'm not in the best form this year but the effort to accelerate was noticeably reduced to the point that I actually enjoyed trying to drop my riding buddy.

It's always subjective but the BU35's have improved the bikes acceleration and climbing for me. They're away for winter now-roll on Spring.

Great Thread!

I just ordered Bora One 50 Tubulars with Veloflex Arenberg to go on my Time Skylon

I'm waiting for Carogna tape to arrive so I can start riding.


Brilliant, very good weight. :thumbup:

Let us know how you get on, especially with the combination of Veloflex tyres and Carogna tape. I'm not yet entirely sure that I totally trust the bond.


Ok, ride report: Tape application was relatively easy and a strong bond has formed under 24 hours. It has been a few hundred kilometres and it's going strong! For the tyres, they are so comfortable even at high pressures, it feels like wheels have disappeared under the frame while riding, if you know what I mean.

I hear you, especially the part about the higher pressures. I run mine at 110/120 psi. With clinchers I never go above 90. The ride feel is amazing. I have half a dozen clincher wheelsets which I'm still using on other bikes, but I very much doubt I'll buy any more clincher wheels. The Bora converted me.
Cinelli Saetta 6.5kg - nice and dry weather
Reilly T325 7.3kg - nice weather but windy
Spa Audax 9.1kg - all weather steel beauty
Pinnacle Dolomite 7.9kg - flat-pedal chainguard thing
M∆SON Definition 8.5kg - off-road ... thing

Now that I have a caliper, I've measured the width of the Arenbergs on my Bora One 50' tubulars. At 90/95 PSI, the tire width is ~24.4. I've not tried the Criteriums on these rims, but I don't think I will do so. I've suffered two flats with the Arenbergs and was happy to see that the tires were wide enough to protect the rim edge. I'm not sure that the narrower Criteriums would provide adequate protection in the event of a flat.

Just about to get some Bora One 50 tubulars and am facing this dilemma myself...

I'm using 23mm Vittoria Corsa G+ tubs on some other (narrower) wheels and they measure nearer 22mm than 23mm (in contrast to some other Vittoria tubs apparently).

If anyone is running 25mm Vittoria Corsa G+ on the newer Boras I'd be really interested to know what the measured width is. If they come in a millimetre or so under too they could be ideal for the Boras as they would match the rim width almost exactly.

I'm 140lbs so don't really need wider tyres for stability/comfort (although added comfort and grip is always welcome). I don't want to lose aero benefits by running a tyre that's wider than the rim, but a 23mm Corsa G+ at an actual width of 22mm seems a bit too narrow than ideal for the Bora 24.2mm rim profile...

<edit - measuring again the 23mm Corsas are perhaps 22.6mm at 95-100psi>

Hello guys,

thanks for sharing experiences with tubulars.

I'm new with tubulars. I just want ask, if maybe someone ride 23mm Veloflex Carbon tubular tires on Bora 35 or. 50, they are wide 24,2mm by specification.
I konw, recomendation is 25mm tubulars, but what can be wrong, if I mount 23mm tubulars on 24,2mm Boras?

Thanks for advice.

2 years old post but this is a good thread if we can get it updated. I'm about to have some vittoria 25c "Vittoria Corsa G Tubular Tire Para/Black 700x25c" to test. It has not been my experience that the width of the tubular rim really affects the resulting mounted section width due to it's autonomy, unlike clincher and tubeless tires. If a 25c vittoria ends up being more like 24, then that ought to be about as perfect as one could hope for on the Campagnolo 24.2 rim width.

My gutt feeling is that the 23 can 'work' but it will not be optimal in any aspect, especially if a 23 is really measuring in less than 23. I am actually curious about 2 different tires I have now, a Continental sprinter and a vittoria cx, both previous generation so the vittoria is not a G series and the conti may not be "black chili" but I will try to post data later this weekend.

I wanted to add that I have been riding tubulars since 1986 and have repaired many by opening and re-sewing back together and have worn many right into the casing threads. Considering the life of some like an older conti sprinter, that's quite the mileage without a repair but there's also the trick with these that later in life you can use the latex sealant to fix small punctures inside without the hassle of undoing and sewing back together.
Unless a person is very skilled at the re-do, a fixed tire will not be as perfectly round at the repair zone and will have to be demoted to being used for a spare or only training wheels.

I'd run dugast strada's cotton personally 25mm brother 25mm real width tubs on rims this width. Dugast are my favourite closely followed by conti competitions (not for there comfort though). In fact I would not run narrower because the tyre protects the rim. If you live in an area with potholes and in the uk we have alot of these tyres narrower than rim mean rims get damaged. I rather loose a few seconds on a ride than damage a rim.

Summer needs to come as I have a set of IRC 25mm tubular tyres to try out.

I'm now running the Corsa G+ on Bora 35 tubulars with 23mm on the front and 25mm on the back.

With both pumped up to 90psi the 23mm front measures about 22.5 - 22.7, and the 25mm rear measures pretty much spot on 24mm.

I'm guessing that the slightly narrower measured width is because the 23mm and 25mm stated widths assume traditional high pressures of 100psi+.

For me the 23mm / 25mm combination is perfect. A 24mm measured width on a 24.5mm rim is not ideal aerodynamically if you believe the 105% rule, but at least it's narrower than the rim and on the rear that's fine. 22.6mm on 24.5 is nicely aero for the front.

I also just like being able to pump both front and rear up to 90psi rather than having to remember a higher pressure for the rear.. :D

The 23mm looks and behaves absolutely fine on the front. Happy to measure them at different pressures if that helps. I suspect that there is variation from tyre to tyre however, and for all I know the current version could be different - mine were bought a year or two ago.
