Is it possible something Dugast applied to their tires (I suspect not)?

I just became the proud owner of some Scheeren hoops built on some nice high flange Campy hubs. I was looking for tubular recommendations for these wheels. My other wheels are a lot narrower so I didn't know if they caused any limitations. From a first look, I think 25's and possibly 28's would fit the bike.

Okay, I managed to read the entire thread (all the way back to 2005) and did not see any reference to Park Tool's set of instructions on mounting tubulars:
http://www.parktool.com/blog/repair-...-gluing-sew-up They recommend 1 coat on the tire which they do before the rim. Followed by three (and possibly more) coats on the rim, 24 hours of drying time after the first and second coats. The tire goes on after the third coat is partially dry (60 seconds to a few minutes) and then dries for 24 hours after the tire is installed. |
One coat is enough on some tires but others have a base tape that will suck up that first coat and beg for more.
|
I think the wide variation in people's approach to gluing tubular tires suggests that there is no one right answer, and that it will be context-dependent (different tires, rooms, used v new, width, etc). On most of my setups (all for the road) I've successfully used one coat on rim and tire, but on my latest setup (wider cx tires, but still on road rims), I wound up with two on each after a mishap on my first ride.

There hasn't been much input here lately, so here's my latest tire mount.
You may notice: - concave, dirty brake tracks - glue strings - glue on sidewall - dirty 10 speed cassette - almost vintage wheel These file tread tires work pretty well for all around (CX bike)- OK on the street, fine on dirt short of mud, and I seem to have a supply of used ones, so when one gave it up, there was another to take it's place. Moderate scraping of rim edges with a carving gouge to remove dirty & oxidized glue & remove a few lumps, rub with scotch pad, coat tire & rim with Mastik from a can with brush that lives inside the can, let dry. Subsequent day coat rim, let dry a few minutes, mount tire, inflate to 45psi, press tire into floor all around, done. https://cimg5.ibsrv.net/gimg/bikefor...ee3cfb8997.jpg |
I have some Dugast Pipistrello cross tubs with a similar thread--albeit with different shaped and lower profile nubs on the edge. I agree that it's a good multi-surface tread. I find Vittoria road tubs wear out a little quicker than other tires--a tradeoff for a nice, grippy feel. I wonder how those will fair with some road use.
Btw, I've found Brasso (metal polish) to be a good glue remover. Safe on chrome & aluminum. It can leave a bit of a film which should be cleaned of rims afterward. (I think I may have mentioned this once before, but it would have been many pages ago.) I like the creative use of the hose rack for those tires. :thumb: |
FWIW I just received 4 of the Servizio Corse tubulars from Yellow Jersey for a total of $78.67. I’m happy with them out of the box. They won’t be ridden more than a couple hundred miles a year. Here they are mounted, but not glued.

You talking about that red stuff with which you had to tear off the tire and re-glue every season. That's OK if you have a mechanic. I say good riddance to that stuff. Vittoria Mastic was a god-send. In years of racing, the only time I've ever had to remount a tire, is when it's worn out or flat. And getting em off, even after several years is almost impossible. Although, I do check em before a criterium or road race with technical downhills.

Asking for you to help me watch Specialized.com
Hey folks -
Please help me watch the Spesh website for any coming sales they have on their top tubulars. Looking at Allrounder 24mm for the vintage DeRosa, where I prefer a black sidewall. Hell o th North = maybe, if the reduced price is attractive, but I got a bunch of VeloFlex 27s. edit= cyclocross now reduced, 33mm with a couple of knobby patterns. After running these, it made me a believer. https://cimg8.ibsrv.net/gimg/bikefor...cacb02fa74.jpg |

Hence my help request on the Spesh tubular. I'm running many brands and the narrower Spesh (24mm) was one of the best, worthy of another purchase years later. |
Watch eBay. From time to time I come across really good deals. Like Specialized Hell of the North tubulars and/or clinchers for about half price. Also picked up four new Veloflex Vlaanderen for about $30 a tire. Some people try these and decide they don't like them. Or their priorities change.

I've got a gift card coming next week - hopefully these'll still be there. I was afraid I might have to learn to like brown walls and linear tread. Black / Green Pave CG 111 28" Tubular 30mm $43.75 |
