Which Tubs?

i dont know if they already have been mentioned, but when i raced the track, i used Veloflex Sprinter tubs, and well, they did the job great i think!

Anyone used the challenge pista 320? Ok for an outdoor track? fast?

Vittoria Corsa Evo CX has done me good on HH the past months

What's a Veloflex Sprinter? I have Criteriums and they are lovely, lovely things!

I've just got a pair of wheels with tubs glued on- they didn't do a great job on the rear, it's attached, but not as firmly as it could be.

What's the best thing to do in this situation- strip it off entirely and glue it as a new tyre, or strip it, coat of glue, bang it back on again?

Should answer your question. Original post had the wrong clip. doh! Try this.

Use meths, our equivalent of denatured alcohol. Be patient it takes time.

That covers mounting a new tub, no mention of what to do in my situation.

One coat on the rim and one on the tub will be enough, IF the existing glue is substantial enough and there are no massive bare patches

Great, thanks.

It was quite scary, yesterday.
We rode with retro track bikes on the wooden track in Büttgen, Germany.
Home track in Apeldoorn (NL, also wood) is usually no problem, because it's less steep.
It seems that old rubber (tubulars, 10, 20 maybe even 30 years old) is not really suitable. Compount maybe too hard, tread worn.
For next time, I'll ensure to use new tubs only on steeper wooden tracks.
Okay, safety first, but I also don't want to spoil the appearance of the nice vintage bikes with all black, red or orange tubulars. I may have to go for modern Vittoria, Veloflex or Challenge with tan side walls.
Your experience with, recommendations for wooden, indoor surface?
Older tubs no-no ?
New tubs, which?

Some tubs go a bit hard when they get old, = slippy on the boards.

There are loads of modern plain looking ones out there which will do the job, avoid conti tempo or anything by Michelin and anything coloured.

Also a wipe over with white vinegar or ethyl alcohol before you ride is good practice.

Thanks for your advice.
Was a good lesson yesterday, that old tubs get hard and slippery.
But the whole velodrome was smelling after my bottle of vinegar. And yes, We made the tyres dry before riding.

I don't believe this. The problem these days is with newer non-carbon black tires--- Contis move back to carbon black with "Red Chili" is a great move forward. Fresh tires don't have better grip. Old rubber is fine unless its cracked or the casings rotted. The rubber thread just needs to be activated a bit. Rough them up with some pumice and degrease with isopropanol--- if the tires are fresh out of storage it might be good to give the sidewalls a bit of liquid latex (which contains ammonia which is a rubber solvent so be careful not to get carried away as too much can do more harm than good).

If the casings are still good but the rubber is cracked one can even--- if these are high quality track tires--- replace the thread.

Its important. I think, to keep in mind that some tires are better suited to some courses than others--- this also applies to road tires used on the road as well.

The thing to avoid is not "colour" but tires that used silica filler instead of carbon black--- and a number of these tires are black/gray including the last Conti comps before "Black Chili".
Conti tempo? I completely disagree. There are among the best tires in the track training segment--- alongside Steher. The Sonderklasse and Olympic Contis are much better but as their name says they are for higher level competition. The comparison I think is much like between Conti Sprinter and Competition on the road--- the Competition is my preferred tire but at 1/2 the price I always suggest the Sprinter as the best budget tubular road tire I know.
For competition there are a number of interesting tires about.. But it really depends upon the course, rider, level and budget..

You're entitled to your opinion of course, but tempos are the last tubs I'd recommend to anyone for riding wooden tracks.
I've seen an awful lot of track tubs in use, and tempos seem fine when new but go hard and slippery very quickly. For the price, there are many, many better options.
In fact, there's not a single continental tubular I'd reccommend over anything else at any level. Riders at top level in the UK tend to use Vittoria pista Evo CS.
Some like the sonderclasse for endurance training, but that's because of durability.

Maybe I should be more specific. Not easy to point out what exactly caused the problems, because there were too many variables / different circumstances compared with earlier experiences.

Fact was that all 3 of us had massive grip problems and we all used older tyres.
I can only speak for myself. I rode with Vittoria Corsa CX, Vittoria Cronometro CS, Clement Criterium Seta. Some tyres had better tread, other were pretty worn. The newer tyres with best tread had the best grip, although not great, not possible to stay on the track at 30 kmph.
As already pointed out, used white vinegar to clean the tyres.

Never experiences such problems at my home track in Apeldoorn. But here the banks are les steep and the temperature is always pretty (too) high.
Sunday in Büttgen, the track was a lot older, maybe ore slippery surface, but (maybe important to point out) no heating. Temperature was around 3 - 5 °C.
Still a lot of riders on the track without any grip problems, riding around with moderate speed, chatting with the hands on the drops, etc.

Somehow I think that the combination of the old tubs with the low temperatures were the cause of our problems.

Evos are great value for a competition tire but totally ill-suited as a general purpose tire-- and totally out of place for training. They are very fragile and extremely fast wearing--- at the elite level, of course, none of these arguments are of any relevance as tire cost is, more or less, irrelevant. On anything but a good track the Evos are out of place--- at at a high level there are much better tires to be had.

Durability is an issue.

Very true.
And if you read my post properly you will see that I mentioned them as a top level tub, and an example of alternatives to conti existing at all levels.

What I didn't do was recommend them as a training tub.

Sorry if that confused you.

I think you are probably right.

And you may already know this, but there's a technique to riding slowly on steep bankings. Keeping pressure on the left foot can help the bike 'dig in' to the banking and keep your grip at slower speeds.
Obviously when riding slowly, kicking back, hesitating and failing to keep pressure on the pedals will usually result in an unplanned trip to the safety zone.

as i'm only riding in the winter months at our "local" indoor velodrome (80km away) which always has less then 5°C i never ever had any issues with grip. it's an old wooden velodrome (200m length, 45°, appr. 4m heigh) and i'm riding a conti tempo II at the back and a conti sprinter at the front. but there are also guys who riding clincher tires without any problems, mostly with a minimum of 145 psi/10 bar.

My 1 st reaction was to use wheels with better tyres and REDUCE pressure from 9 to 7.5 bar, thinking that this would improve the grip. Was that wrong?

potentially not, it will increase your contact patch but might roll slower through corners

That's clear. Point is: I wanted to go slow/relaxed, but was lacking grip.

Recommendations for tubs to ride at HH please. I've had Vittoria Pista CS on this year, they are the first tubs I've ridden and seem very nice, but am I missing a trick by not riding something with a higher tpi?

edit - just read RPM's first post on this thread (lazy me) - Pista CS it is again. If it aint broke...
