Lumpy Tubulars

Jamie said:

Do they make non lumpy tubulars any more? I just put a new set of Conti
Sprinters on some carbon rims and their is one "lump" that I can't get
out....and I KNOW it's mounted right and that the rim is not off. There
is literally a bulge or
something in the tire. It drives me crazy when I'm up to speed on the
bike. I talked to one of my buddies and he said that's one thing you
have to accept about tubulars? This can't be true? Is it? Is the more
expensive Competition any better? Other brands that might be perfect
and round?

My Conti sprinters are round and perfect. But the Vittoria Cross tires I just
glued up, one has the stem about ten degrees off from the centerline of the
tread.

Grrrr.

Maybe I just got a bad batch? 🙁

My experience with Conti Sprinters was less than stellar. IME, lumps
and "wiggles" are par for the course. I relegated them to spare tire
duty.

IME, Conti Competitions are great tires, but very expensive. When I
wore out the last of my really lightweight tubie rims (Mavic GEL front,
GL rear), I gave up on tubies. No regrets.

I Use Sprinters on my Merckx and they are pretty round, IME..warranty??

Torelli and Vittoria seem more lumpy to me.

I'm wondering if anyone inflates their tubulars up to rated pressure off
the rim. This can damage the casing and can cause bulges in the tire.
I've yet to hear about honoring a warranty for a glued tubular.

You know, I was thinking the same thing...ie about inflating the tire to
high pressures while not on the rim. It seems that I've seen sites tell
you to do that to "stretch" the tubie...but I do agree, by doing this it
seems like you would almost "distort" the casing?

Any one had any luck/experience with high end Tufo tire? I've used some
of their cheap tubies for a training set and it wasn't the most round
tubie I've ever used...but it was a training set and was pretty cheap?

Does Veloflex make tubies?

Even name mfr's make mistakes. One of my Cinelli's had the front
brake mounting hole about 10 degress off; fixed now, (Bridgeport and
sleeve).

See a urologist.

Schwalbes seem good. As do Continental Sprinters.

It's possible that the lump is caused by the hole for the valve in the
rim not being large enough, and so the tire isn't seated well enough
at that sport.

'Stretching' only occurs on a rim...lots of air into a tubie w/o it
being on a rim doesn't do anything and 'can' tear the casing...

Lumpy tubulars happen all too often even among the high end models.
I've had better luck w/ Conti Comps than Vittorias CX's for consistant
roundness. You might try regluing the tire as uneven stretching while
mounting could cause and out of round situation.

IMO Veloflex makes some of the best tubies these days. I use the
Criterium model as a replacement for Vittoria CG's and run 'em on the
rear. Still using up my old stock of CX's for the fronts and will move
to the Veloflex Record as a replacement though I've got a Deda aging
and will try it out one of these days.

As for training tires the Conti Giro is okay as well as the Vittoria
Rally. Just expect a shorter life than the high end tires. Then again
you may get lucky and get thousands of miles out of 'em.

Not big on Tufo tires as I'm not a fan of their solution for fixing
flats with sealant. I'd rather have a tire I can open up and repair.

Good luck,
Greg Hall

You know, that really isn't OK. There is no reason why a $70+ tire
shouldn't be round and straight. Clinchers are, even at less cost.
Tubulars _used_ to be.

I don't know; I've had good luck with Vittoria CX and CG,
but they are quite expensive now.

There's something wrong when you can get a CX from the UK for half the
US price, shipping included.

My problems with lumpy tubulars have so far been limited to cheapies.
No problems with Sprinters or CXs (so far).

Agreed, once is too often and yet it still happens. For me this was
more of a problem when Vittoria production went to Tailand (or was it
Taiwan?). The inner tube quality suffered as well.

My recent experiences w/ Veloflex has restored my confidence in quality
non-Conti tubies. I've yet to have the problems I've seen in older
Vittorias and hope it stays that way.

I started out with Tufo S33 tubies. They were great for about two
weeks, then wore to a flat profile. I was always checking to see
whether my brakes were rubbing. They were replaced by Vittoria EVO Pave
tires, which have been outstanding. I finally understood why tubies are
said to be superior. Mostly, it's the fact that tubular wheels are
significantly lighter than clinchers. I've been using the Tufo Extreme
tape, and it seems to be doing the job.

I also used Tufo tubular/clinchers for awhile. They seemed to wear
better, but even with the sealant inside, a small puncture pretty much
ends the tire's life. I replaced the Tufos with Vittoria Open Tubular
CX's; after I wore them out, I got some of those Revo KXS reversible
tires. They are wearing very well on the slick side, and when the
weather turns, I'll just turn 'em over for the treaded side. I got an
extra set as well, so I'll have tires for a long time. I usually put
the tubies on in the fall, and prefer them on crappy roads.
Stay Cool,
Tom
