Some peep holes asked for it...

Gluing Tubulars

I didn't write it but Brooke did.

The method i've used isn't terribly different, certainly not worth attempting to communicate my variations only to have someone mis-interpret them and screw up $175 of FMB Racing Ralph goodness...

Check it out. Seriously, it really isn't that hard, doesn't even have to be that messy, gluing them on. And there really is no excuse for a rolled tubular.

At least the consequences of a rolled tubular in cross aren't as scary as it is on the Track.

Oh and i gotta say, it is hysterical seeing rims that have been languishing in bike shop rim bins for 20 years laced up to modern hubs... really actually pretty damn funny. All the crappy FIR and off brand (non-mavic or campy) rims that shops couldn't unload between 1985 and 2005. Stuff that was acquired in the 70s, now seems to be flying off the shelf. I wonder if Velocipede Peddler still has the 2-3 linear feet of tubular rims still sitting there under the wheel building bench???

Oh, just found this method:
with tape, i'll say this - the tape looks right retarded used in that function. Go with Brooke's recommendation- don't use tape. But, be careful. Follow up post to that story was that he rolled his tubular the next race it seems! Murphy's law is a bitch. Here's to hoping Brooke's method is so sound and tried and true that he doesn't roll one in the next race.

That all said, i'll add this: A properly glued tubular should NEVER roll off and should let you turn way too sharp even without rolling. But, i also ride clinchers, so what do *I* know.

Campy rims, especially the tubulars, were WAY better than Mavics in those days. GEL 280s? No thanks. GL 330's and GP4s are fine, but the seam was always "soft." Campy rims by comparison, even the very economical yet light Victory line, were much easier to build up round, IMHO. I'm still riding some of these that I scored for around $30.

my personal favorite - as a mechanic...

was the Mach2CD2

dunno - kinda one of those things that just made me go... that's cool...

280s... ya had to be 125 pounds and wicked easy on wheels to get away with riding on them... one pot hole and you gotta buy a new rim...

solobreak said...

I never built a Mach2CD. They were heavy. Not long ago nashbar had them in 28 hole for something like $25. It took quite a while for them to disappear.

I have a pair of Record Pave's 28h laced to 7speed DA hubs. Odd mix, but sweet wheels. Very low miles too.

I can't believe there is any debate over this still. Tape and glue together is simply the only thing that works if you never want to roll a tubular in cross, or worry about it.

The tape/glue method described in the link is JUST WRONG though. See, he rolled his tire. First mistake was using the "Extreme" tape, I know it sounds counter-intuitive, but the Tufo "standard" tape works better because a) it is wider and covers the whole rim b) it is thicker and more flexible.

I use the glue/tape method I guarantee you couldnt try to roll a tire if your life depended on it. In fact you better hope you never get a flat because you practically have to burn the tire off, of done correctly:

solid instructions here:

but read this one first...
http://www.bikeman.com/content/view/92/59/

Note that he is using "Extreme" tape initially, and then changes his mind in the update article.

Trust me...Grifo tires, Tufo standard tape, and a can of Mastik One glue - you will never be let down.

gewilli said...

Sven,

Yes - i've seen the Bikeman write up...

but what Brooke's saying about the tape makes a helluvalotta sense...

did ya check is method and rational against the tape?

And yes. He's using the tape wrong AND using the wrong tape.

That said.

I still think tape is stupid. If you glue the damn tire on right it won't come off any differently than if ya used the tape...

me no like the tape - it stupid (yeah i'm calling something stupid).

And since when did ya start racing on Grifos? Ain't the Rab team sponsored by Vitto?

gewilli said...

i know cyclocrossworld.com shows Sven's bike with 32 Dugasts on them...

but...

well recent shots seem to have him on silver tread tires that look a lot like a vitto

Colin R said...

I ride clinchers because I'm not smart enough to understand what you guys are talking about.

gewilli said...

i ride clinchers cause i ain't got enough money to toss at tubulars...

Moveitfred said...

Fahk, G. Don't you have bottles and cans where you live? Throw em in the back of that trailer you got, take em to the grocery store. They got a machine that gives you money. No questions asked.

Am I missing something?

1) One can of Mastik’ One 2) One Package of the Tufo Gluing tape (not-extreme, just regular) 3) One Acid Brush (keeps it clean)

He did use the regular tape, so why did it roll? Also, could you use Conti glue or is Mastik critical to this setup? I'm actually curious. I too believe that taping isn't necessary, but want to try it so I can make a fair judgement.

By the way, Sven is rolling around on Dugast Flying Doctor's with white treads. Stu has them.

I was inspired to write my post about gluing after I saw one too many posts about people using tape.

Chumps use tape.

The Euros? It may be called Belgian method but the Pros just glue.

The Vittoria tape is okay. The Tufo tape sucks. I did it. I did it right. The mud eventually corrupted it faster it would have a good glue job.

For the record, I've tried both tapes -- Tufo (regular) and the Vittoria. The Vittoria tape stuck like a mofo. The Tufo eventually was compromised.

The thing that turned me off to the tape was removal and reuse. I tweaked a rim but the tire was still good. Removing the tape from the tire took lots of work and skin. I tore a tire but the rim was still fine. It took me lots of time and effort to clean the rim so that I could use it again.

If I'd have used glue only, both of those ordeals could have turned into a couple hours of total work to have the tires reglued.

Can I say it again? Chumps use tape. Period.

Fair enough. Can someone get me the link to Brooke's post about gluing? I still experiment with different methods and like to see what other people do in case it's better than me. Thanks.

By the way G, "never" is a strong word. At some amount of force (and with a little googling you can find the numbers) every tire will peel off. As someone recently said to me, "You think Tim Johnson had a rookie gluing his tires before Glawstah". A portion of what holds a tubular on is the air pressure. Take that away as you do in cross and you're relying heavily on the glue joint. Cornering in a race can put enough force on that joint to break it. Doing it right minimizes your chances of it happening, but never just doesn't fly. Splitting hairs I know...

Related to this, saw a comment from Katie Compton recently on tire pressure: "If you don't feel the rim every now and then, you're using too much air pressure".

megA said...

wow this blog post explains a lot:

1) i am a chump
2) i use fir rims

oh well

zank said...

I am a chump too.

That's fine though. I'd rather be the chump with bloody fingers trying to get my flatted tubular off than the chump running to the pit with a rolled tubular.

gewilli said...

i could have picked Fir, Ambrosio, um... besides mavic, fir, ambrosio, campy... hmm... i can't come up with any 70-80s era tubular rim names...

and Zank, Meg, neither of you race in wet challenging conditions...

;)

next time you want to take the taped tubular off? soak it in a puddle of water

Me? i still think tape is stupid.

Why?

Look at it mechanically. Not only do you have to make sure the tape is glued to the rim, then you have to glue the tire to the tape.

WHy not just freaking glue the tire to the rim? Using good strong adhesive.

illogical

megA said...

honey.

you are a science guy.

i am a literature girl.

logic is lame. it is boring. it is unromantic.

if life was logical i would be bored to tears.

i enjoy my logic-lacking life.

i hope you enjoy yours too, mr. spock.

xoxo, oooooops! love isn't logical either,

x=y+z,

zank said...

Sorry, G, but you are off base on this one. Maybe with Tufo tape, but not the Mastik tape.

gewilli said...

hahah...

off base...

tape, base, i think Zank made a funny...

Still - i go back to saying what is the tape anyway?

Adhesive?

why not just get a tube of that instead?

i dunno...

i don't run tubulars, when/if i ever do i won't be using tape...

the process is made more complicated with the tape it seems... but maybe not... i dunno...

i shut up about tape vs glue alone from here on out...
