Tub novice tips please

mroli

So going to get a set of carbon tubular wheels, currenlty ride clinchers (Conti gp4000s), but like the idea of riding with Tubs, have gleaned as much knowledge as I can from here, but could do with specific tips - namely:

Glue or tape? I have seen pros for both and am confused.

What tubs to buy?

Do I carry a spare tub (I won't have any used ones!) or sealant - if so, which one?

I will be using these wheels for a bit of time trialing and a bit of general "sportive" type riding - they will be going on my "best" bike...

Ta for the tips in advance!

Glue or tape?, can of worms, I use tape (jantex)

Which tub?, can of worms, I use Vittoria Corsa Evo CX's

Carry a spare?, in theory you should, I run tubs in open TT's only, but never bother.

Tape.
Corsa CX has been the best road tub for the past 30 years.
You need to carry a spare, but it only need be a cheap one to get you home.

mroli I am thinking of going down the same route! check out Youtube vid for Mark Purdy gluing/fitting tubs. Also the 98page thread on WW for gluing tubulars :shock: or maybe just watch the vid's instead.

Glue.

Conti Sprinters - not too expensive but still roll very well.

A Google search will show you the best way to fold and carry a pre-glued tub.

I used Conti Sprinter tubs as my everyday tyre for over a year. It worked out no more expensive than running clinchers the year before. They are easy to change (easier than clinchers anyway). The only downside is if you get a couple of p***!!!*@£s in quick succession which would be costly.

Tape-jantex

Carry a can of Vittoria Pit stop

Conti Giros or Sprinters(easy to repair yourself) and fairly durable

mroli

Ok, so far we have it down to:

Glue or tape (which sort of both would be good!) with glue probably just ahead

Vittoria Pit Stop for sealant

Corsa CX for "special", Conti sprinters for everyday

Carry a spare if doing long rides...

Keep 'em coming - ta....

I'd go glue if you're carrying a spare tyre, I use Pit Stop as I don't carry a spare as I use my tubs solely for racing/TTing.

I did london to brighton yesterday on my tubs. My belief is that if you have fancy wheels ride them!!! Life's too short to occasionally use fancy kit if you have it, I find riding far more enjoyable that way.

My mate who is a mechanic at a shop very kindly does my tubs for me with both glue and tape!!

Tyres: Continental Competitions, from past experience I found Vittorias a bit quick to wear
Spare: 1x Comp which has previously been repaired. If its a long ride on questionable roads then also 1x new Vittoria Rally.

London to Brighton on carbon wheels and tubs :roll: Guess you needed all that aero advantage when drafting those big packs at high speed

Glue. I have heared some tapes can pull out carbon fibres but not Jantex which is quite tricky to use.
Always carry a spare. Two on a long sportive.
Vittoria Corsa EVO CX are good but quite delicate and have to be pumped up everyday due to their latex inner tubes. They are repairable some tubs arent – usually the cheaper ones.
Conti Competition are more robust and have butyl inner tubes. Also repairable.

They couldn't really get any less aero at 20mm. Anyway, those large packs were drafting me :twisted:

Just to add Continental GP4000 tubs are NOT repairable.

A question for the experts: how long after gluing on a tub is it 'safe' to ride?

APIII

Usually leave them overnight just to be sure.

What do you do if you ve punctured and have to replace the tub then?

(very much a novice but window shopping for a fancy road bike now I'm in Holland where MTBing is less common)

Billy Dunlop

Tape.

Veloflex tubs.

Must admit to having few punctures with tubs so experience is limited to maybe a dozen over 30 years and I admit to being out of date . I much prefer glue as it leaves some on the rim when you remove a tub with a puncture. This then helps the replacement stay on although maybe not so well. A used tub will also have some sticky left which adds to the bond. I have yet to get a taped tub off that leaves the tape in place perfectly. Bloody stuff always comes of both rim and tub or stays with the tub which leaves little or nowt in the way of stick on the rim for the replacement. Maybe someone carries spare tape? Never heard of that.
For a spare hunt around the proper bike shops for used tubs. They will do to get you home and will be nicely stretched and maybe tacky.

Yep the spare tub should be pre glued in the event that its needed. Conti say 24 hours before you ride a glued tub and 3 days to stretch a new tub on a wheel before gluing.
