how often should you re-glue tubulars?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

how often should you re-glue tubulars?

During a race this past weekend, I hit a pothole and knocked my rear wheel out of true. This evening I took the tubular off so I could get the wheel trued. What I noticed was that the glue wasn't as tacky as I expected and found much of it a bit crusty and dried out on the outer edges, but still tacky in the center of the rim.

I glued the Vittoria Corsas using the Vittoria glue roughly a year ago. At this point I'm going to remove the front and re-glue it as well. My question is, how often should one re-glue tubulars as preventive maintenance?

thanks

I think after 6 months, you should check the tire every month. I've pretty much gone with conti glue...I've had other glue go crusty on me before but had good luck with conti.

Glue them right and maybe every year you check them. I get paranoid after two, usually reglue after a year to a year and a half.

I install virtually every clincher without using tools, even new, unstretched Michelins on Campy rims (or whatever everyone says doesn't work) so I have reasonably strong hands.

But it takes me a good 5-10 minutes to start taking off a tubular tire that's well glued. I have to use something like a slot screwdriver or a spare (individual) cog to pry my way carefully under the tire. Once I get enough tire off the rim to grab the tire with my fist, I have to use considerable force to pull the tire off.

Don't yank too fast, you'll damage the base tape.

I've used, in the last few years, Vittoria and Conti and liked them. I prefer Vittoria. I tried and hated Panaracer (dries too quickly, too watery), but it was the only tube I could buy so I did.

A year to a year and a half.

Usually I don't have tires sitting on my rims for more than 8 months since my wheels do double duty for cross.

I don't think I ever reglued a tire just for sake of regluing it.

why did you remove the tire to true the wheel? was a spoke broke? was there a flat spot?

you don't have to pull the tire off to true a tubular, unless it's a HED jet or alps.

Thanks for the replies.

They're glued properly, but I'm going to re-glue the front for piece of mind since I'm re-gluing the rear. They are Reynolds tubulars so the tire has to come off due to the internally hidden nipples.

In my experience, I've never had to reglue a tire before it flatted or needed replaced. One race season and the tire's ready to be replaced.

Me too.

I've gone two years on cyclocross wheels too with no problems stored properly over the summer. But if it gives you peace of mind then no biggy to rip it off and reglue it.

my main race rear wheel has been getting a bit worn in the middle and just got a leak. I will probably replace it rather than use Stan's. I think I glued it on after Lancaster last July.

that is another reason I love the simplicity of a nice box section tubular.

Plenty of aero and semi-aero wheels that have the nipples on the outside too. But yeah I love box section too.
