Whao, Gaucho. That is ugly. And, it seems odd for your location but maybe not, .... that looks like mold or mildew where the base tape glue was! Ye gods.....

Not quite so noisy. |
+1 for spacing just above the tire. They last longer too. Bend them to the profile of the tire to get the radius to the sidewall and cover all the tread.

I don't know if it's the Vittoria glue, which I used in lieu of the usual Continental glue (I got the Vittoria glue as I just happen to stumble upon them on a trip to an LBS) that had caused the gluing job to fail at the front wheel, but I do remember using just as much glue as I used on all the other wheels I have installed in the last couple of years adn I remember making sure, as usual that I had good base tape and rim coverage with the glue, I have a feeling it's the different base tape construction that might be causing a need for more glue to get proper adhesion. The Veloflex seems to have a coating over the base tape that all my other tubs do not have. Either the caoting was casing a different texture than usual that might require more glue than usual or maybe I just have to clean it real good maybe iwth some alcohol, so the glue will stick to it better.... I'll find out when I re-glue the two tires sometime this week, If I find time..... This time I'll use Continental glue that I already have and I'm more used to....

Wish they still made the "Old Red" Gutta.

I just did one, and darn if I won't have to peel it off and do it again, I get a "squishy" sound as the rear wheel rotates at one point. New tire mounted very true, and feels bonded butI don't like the noise.

I do 2 layers on the base tape and one on the rim. Works fine for me (WFFM). I often leave a spont opposite the valve with less so I have a place to remove the tire. After a few runs the noise goes away. The last two rims I didn't put any glue on the base or the rim on a 3/4" or less section and have no noise at all. This is with the YJ tires.

At sometime in the early days of this thread I was persuaded to try a better tyre than the Rallys and Gommitalias that I was familiar with and ended up getting a pair of 25mm Veloflex Arenbergs. I was immediately smitten by their ease of fitting, the evenness of their construction, their nice grip on rough surfaces and their plusher ride. Since then I've changed almost all my machines to the same tyres and the ones I haven't are because I'm waiting for the old tyres to wear out. I chose the Arenbergs because they were available in 25mm.
However, the one drawback is that they need pumping up every day. This is due, I have since learnt, to them having latex inner tubes. I sometimes pump them up twice in a day if it's a long day. Can anyone recommend a tyre that's as nice as the Arenberg, in a minimum of 25mm (up to 28mm would be fine) with a butyl inner tune which holds air longer? Preferably black but with tan walls would be okay. |
Does anyone know if Vittoria Pavé tubular tyres have butyl inner tubes. Can't find the info anywhere. Their website doesn't say...

I'm using the Challenge Parigi-Roubaix 27 mm tubulars now, and if I ride every two days they need pumping that often to get up to 7.5 to 8 bars. |

I can't say, but maybe someone who uses them can say for how long they hold pressure? If when new they need to be pumped every day or two, they're latex. If it's considerably less frequent (a week to a few months), they're butyl.

http://www.bikeforums.net/showthread...th-butyl-tubes P.s. Note that some of the recommendations in the thread linked above were latex tubs. Tufu cross tires with a diamond tread may be your best option. I briefly used some 34mm Tufu's but I didn't have enough clearance with fenders so I took them off.. They worked fine--seated well and gave a soft ride--though maybe a little sluggish. I'm now using 32mm Dugast Pipistrello tubulars on the same bike--awesome, but very pricey, and latex tubes. |
I've never had tires hold air like my Tufo Diamonds, either tubular or clincher. They're great on hard pack and grass because that's what they're designed for. On the road, they're not so great. They ride more like cheap clinchers than tubulars. One of these days I want to try Tufo's road tires.
I think I recall Robbietunes posting that he races on Tufos. The Tufo tape is great for a dufus like me that can't glue on a tubular without getting glue all over the tire and myself. I think I'd go for blackwalls in this case because Tufo's tanwalls inexplicably tend to turn black over time. http://imageshack.us/a/img6/7611/7dv8.jpg |

That's a good question!

Dawes-man, I sympathize with your quest for a wide, good-quality, butyl tubular:

Perhaps even if they made a lovely tyre with lots of feel but a butyl inner it might not sell in enough numbers to make it worthwhile. Hence butyl is consigned to cheaper tyres. I'm sure there is a long list of things that make a tyre great. I very much doubt I could tell the difference between an Arenberg with a latex inner and the same tyre, built in exactly the same way, but with a butyl inner but I guess a lot of pros could. |
Just had a thought: www.tirealert.com. For ~$20 (discounts for multiple tires) they can replace the latex tubes with butyl tubes and add new base tape. I just spoke with someone over there who confirmed wide tubulars are not an issue (they do repair cross tire, too, after all; they can also repair with latex if the customer prefers). So, if you are willing to add $20 to the cost of a tire, the options are about as limited as latex tubulars. If I get a flat on my 32mm Dugasts, this is what I'm going to do. Disclaimer: I have no prior experience with tire alert, but it's something I've considered (actually, I probably heard about it 15 pages or so ago on this thread).

I'm sure I could not tell the difference either. Not like the difference between good tubulars and my clinchers, say.
I've also heard, way back when, that thin latex adds to the supple feel of good tires, but I'll wager most of it is in the casing and sidewall construction. Like the difference between a really good silk tire and a so-so cotton tire. |

I can't say I've experienced it, but latex tubes are said to give a more supple ride. I own and use some latex tires, but I'm not sure they're great just because of the latex.
