Here’s the deal. My disc wheel came with a 19mm Tubular tire that is almost new. I just bought a tubular trispoke for the front, but it doesn’t come with a tire. Is it possible to remove the tire from the disc and remount it to the front and buy a new tire for the disc? I wanted a bit wider tire back there anyway. If it’s possible, is it advisable? What sort of effect will it have on ride quality? Thanks.
Just be careful when pulling the rear tire off. Make sure you don’t rip/destroy the base tape. If you do tear the base tape away from the stitches, re-glue the base tape back onto the tire. Other than that it’s as easy as you’d imagine.
Sweet thanks.

X2 on the above. You will most likely have to remove some dried glue globs off the base tape. The best way to do this IMO is to pump the tire up a bit to give it shape and then scrape the basetape with a utility knife. Be patient and of course very careful. If the glue on the tire isn’t too thick and/or dried out a couple of coats of fresh glue will reactivate it. It’s a good idea to smooth the existing layer out and trim off any loose material or globs standing proud. Try to fill in any areas where the glue has pulled off the rim with the first coat. Then install the tire immediately after the second. Also a good idea to stretch the tire after the second coat of glue on it has dried as the new glue will tend to shrink the tire when it dries. Good luck.
Curious as to the tires you have in mind ??
Right now I dont have much extra money, so that’s why I’m re-using. The tire I have now is a Tufo Jet Special 19mm. I will mount it on the Specialized Tri-Spoke front and I’m thinking I’m going to get a Gommitalia Espresso 21.5mm for the rear. It will mate to my X-Lab Lenticular Disc.

Thanks - I haven’t tested either of those tires but both the Tufo and Gommitalia tires have butyl tubes (Tufo of course doesn’t have a discrete tube but a layer of butyl rubber fused to the inner surface of the casing). This means that these tires won’t roll all that well. You indicate that money is tight which is understandable these days but Pro Bike Kit has some really good prices on the Vittoria CX 320 tpi tubulars - using the USA10 discount code to get an additional 10% you could get a 21 for the front and a 23 for the rear for ~ $116 delivered (free shipping). You might be happier with the Vittorias overall.

Really… Hopefully you are not being serious - you are maybe talking about fractions of a watt. If his race comes down to fractions of a watt… (and he’d make more of that up by switching to clinchers anyways, but that’s not what this thread is about…_)
I just put 2 new Vittora Rubino tubies on my road bike, and they were like $22 apiece. Yellow jersey has a pair and a spare for $50 of the tubies they “comissioned” ( http://www.yellowjersey.org/tt.html ). I have used both of these in the past, and either of these will work fine. If someone wants to bitch about the butyl tubes, that’s just crazy. That said, I do run Tangentes on my new Zipps, and I love them…

Yes, I am being serious. The difference between butyl and latex tubes will be ~ 5 watts for a 200 lb bike and rider at 25 mph. Several examples/comparisons in the tire data on Bike Tech Review. There are fast rolling options for both clincher and tubular as well as pros and cons to each - well discussed in the bowels of this and other forums. I’m just offerring a suggestion - the OP has budget constraints and may need/choose to use the tires he has as he has indicated.

I’ve read that data too, but I just don’t buy it in a real world situation. TT just had a sprint race (11 miles?) averaging like 22.5 on the bike. I don’t see a difference in tube/tires to have an effect on that.

Are you implying that Al doesn’t live in the “real world”…or is that just your cognitive dissonance showing?

Five watts demand reduction would be ~ 10 sec faster over 11 miles. I can think of at least 3 Masters Nationals Time Trial age groups where the difference between first and second was less than 10 sec over a slightly longer course. If you calc average speed the difference will be very small but that small difference can BE the difference.

I stand corrected, 10 seconds is not completely insignificant.
I’m no where close to 200 lbs. 153-155 on race day is the usual target.
And your bike probably weighs about 17 pounds, which brings the total up to 170+.
Calling me fat?
