I fold mine like Geoff above, but I first roll the tire while expelling all the air out. Then close the valve. After I'm done folding, I take some black electrical tape and throw a couple of loops to keep it as tight and neat as possible. It allows me to make it so tight I can then place it inside a sunglass bag and put it in my pocket

Hmmmm. I like the electrical tape idea. We always use those big elastics from broccoli bunches (hey, road guys are cheap...).

Yeah I use electrical tape on mine, holds pretty tightly and doesn't seem to get any loss of "stickiness"

The double row folding is great indeed. I'm using a small unglued 19mm Tufo for spare, and carry it in a tool bottle. There's even room left for CO2 cartridge and multi tool. The rim has enough glue left, in the rare event of a flat tub (once a year give or take).

Out here, there is too much distance between towns to run a single bottle, hence the under-the-saddle routine. Great choice for interval days, though.

Hi folks.

Well, I've actually read about 135 pages of this thread!!! Great info, great thread!
After a wee wait for delivery, I finally collected my wheels on Wednesday.
Gigantex 38mm carbon tubulars on Chris King R45 hubs with Sapim spokes.

Applied the first layer of glue to both rims and tyres (Vittoria Corsa Evo III) on Wed and a 2nd layer on both today. Used just over 1 tube of Mastik 1.
I think I've covered edge to edge and there's only a wee bit of glue on the brake tracks.
I've got methylated or white spirit to take that off??

Plan to add one more layer to the tyre tomorrow and fit the tyres!!
Quite excited and nervous at the same time! :)

I'd planned to use the same tyre as a pre glued spare but should I go for a Tufo for space saving?
I wouldn't have to remove the Vittoria and glue again at home would I? (I'm sure it's been mentioned!!)

Anyway...thanks for the info.

I'll update you!!! :)

The adhesion of a pre-glued tubular (used for an emergency) is nowhere near the same as a properly glued tubular.
The tyre could roll off if you go around corners too fast, or slam the brakes on.
If you have to use the pre-glued tubular for an emergency, your race is over, take it easy and get home safely.
Once home remove and re-glue properly.

Cross bike tubular wheels- must I use Belgian tape? I called one bikeshop & they didn't offer this.

@RC865, generally speaking, you will want to ensure that the quality of the glue job on the new tire is as good as possible. Accordingly, you will probably want to take the spare off, check the quality of the glue job and make sure the tire is straight, etc. Personally, my spare is an old tire that is too worn to leave on the wheel anymore, but hasn't punctured.

@stl516, my theory is that the basetape profile of a 'cross tire resulting from the greater tire diameter of the tires (as compared to the road equivalent) results in a requirement to 'build-up' the rim bed to 'fill the void' that results from that interface. In addition, I think that the greater shearing forces that are experienced by 'cross wheels are better controlled by the added 'structure' that the tape provides helps to prevent the tire from 'squirming' around on the rim bed. With respect of where to get it, Stu Thorne carries a very good version on his website. I would recommend ordering that, as you will know exactly what you are getting.

Cheers. So, would you recommend me using a Vittoria as a spare or a Tufo that will fold up nice and small?
I can't fin fit, but I'm sure I've seen a picture of a Tufo that rolled up the same size as an inner tube?

Also...I'm just in from the garage where I've mounted my tyres!! :)
I 'think' it went ok!!

2 layers on rims and base tape then the wet layer on the tape and on it went...pretty easily.
Probably down to my technique rather than the tyre!

While there seems to be an even bit of base tape showing, I spun the wheel and kept an eye on the tread. Pretty easy to see any changes.
It probably isn't 100% perfect though. Certainly no wild variations at least.
Am I sounding nervous now!! :) :)

Tyres pumped up hard and hanging in the garage.

Just some glue on the rims and tyres to clean. White or methylated spirit doesn't seem to be doing the job....maybe I have to wet the glue enough and run harder??
Just buy Goof Off?

Also....since my Vittorias have been stretching in the garage, the sidewalls have taken on a not so nice greyish hue. Just need cleaned?
Can I restore them to all black?

Sorry for all the questions and thanks again.

Looking forward to my first ride!! :)

this pic?..

i don't worry about a bit of glue on the sidewalls, for the brake tracks/rims white spirit will do it, use a coarse cloth and rub harder, afterwards i use acetone or isopropyl alcohol to remove traces of oil from the white spirit

at least with veloflex i find aged tyres acquire a patina, it's how you know they're ripe, i'd leave it alone, no one but you will notice

Cheers. Looks like it only comes in 20mm.
Wouldn't be any good for my 25mm rims would it?

Anything else that folds up small?
