Tub advice please

Neil M

Hi Guys, I've just got myself a set of bontrager aeolus 5's for racing on this year and was after some help with Tub choice??
I been looking at the Vitoria corsa evo cx that wiggle have half price at £35
Or continental Gp 4000's that seem to be a popular choice.
Any pointers or help would be appreciated.
Cheers

The corsa evos are one of the fastest rolling ones in tests. I use these and really rate them. To better them you'd need to look at Veloflex or handmade jobbies from Dugast or FMB. You can usually find them around £35-40, so that price is good but not bargainilicious.

Sorry for the bias, but I don't get on with Continental products. Others do rate the GP 4000 particularly though probably more in the clincher version.

Neil M

Cool, thanks mate. I was hoping someone would recommend them, just wanted to make sure before I get them ordered.

Neil M

Sorry one last question 21 or 23c??

Theo-saurus

yes get evo cx great tub, I race it in 23 and 25.
if your getting it for road racing or even tt then defo go for 23 or maybe 25.
conti road tubs a butyl inner so don't roll so nice

Theo-saurus

also the removable valve is great you'll need the longer ones for those wheels

Theo-saurus

before but them quickly check out planet x, I got a vittoria pave tubular for £27!, they have some good discounts but the stock isn't great

Vam Polecat

Agree 23 or 25. I tend to go with 23 as it allows the weight weenie in me to shine

Theo-saurus

of course 25s on the tough rims (soon to be 27 pave) and 23s for weight weenie wheels

Neil M

Haha cheers guys, that really helps.
Can't wait for the season to get started now :-)

This, my friend, conatins actual measurements of tyre performance. Srong stuff. Conti GP4000s are not tested as far as I can see, but the Vittorias come out smelling of roses. LINK

Fact versus opinion.

the problem I've always had with the rous test is that they had the tufos at 1.5-2 bar too low.
If you ignore the 24mm gommitalia (ambrosio) then the vittoria is only second to the veloflex.
Veloflexes are so similar to vittoria because they are made by ex vittoria staff in an ex vittoria factory, most tests show them performing the same but vittorias normally have the edge on puncture resistance.

Oh heavens....tub talk.
Neil you would not believe the amount of talk that goes on by the above regarding cyclo cross tubs, my email looks like War and Peace with knobbles on.
However, these chaps really do know their onions!! Ask them about the best gluing on techniques...go on i dare you

Ha HA

Have not logged on for a few days and top of the shop is a post titled tub advice with 13 responses. Do you think Neil should be invited to the tub club email list?

geoffg

seriously nerdy thread this..hahaha
anyone tell me how TUFO tubs rate against vittoria etc.
good to see the forum back to bike stuff :-)

Vam Polecat

This is another, more exhaustive, list of Crr of different tyres. It used to be freely available, but now, sadly, you need to pay to get the whole thing. Perhaps it will be sufficient for your purposes to know that there are TUFO tubs on the list, and that they are not on the front page Butyl inners and relatively stiff sidewalls hurt TUFO on the Crr side, although, of course it makes them more robust and easier to repair.

Also worth noting the comments regarding gluing.

Theo-saurus

tufos are well known for the harsh ride but get much better at high pressures.
But I think they're the toughest cross tyre

Neil M

Thanks again for the help guys, I've ordered a pair of the vittoria's.
Questions to follow about glueing!! Haha

Senecio [Daniel D]

Congratulations.

Glue - Vittoria Mastik 1. Do what is says on the tin, although letting the glue dry on the tub for longer than advised will not harm and it will be easier to handle.

If you want to mask the braking surface electrician's tape is the best as you can persuade it to follow the arc of the rim.

Mastik One Neil, that's the one you want. Do not waste time and money on Continental carbon specific glue, it's not very good.

Theo-saurus

Mastik is the only way to go for carbon rims.
As the conduct heat faster than aluminium it can melt some glues, so carbon specific ones are made which are more resistant to heat but also more brittle and can damage carbon when removing the tub. Mastik is suitable for both carbon and alu and is also the strongest bond.

PeterG

I can do you a good deal on Electrician's tape :>

tduckett

Agree that the Conti carbon stuff isnt very good, but regular Conti is fine. And agree that 24 hours between applications is best.
As to how many layers, which technique, preparation, getting them on straight etc, well.....this thread might run on a bit!

Neil M

Mastik one also now ordered.
Think I'll drop them in tri sport or Kinetic for fitting, save making a mess haha

Vam Polecat

I can't tell you not to do that Neil, but I will make the following points:

1. The only tubs I have seen get rolled in use have been shop glued ones.
2. There is no other job in cycle maintenance that gives you as much zen as well glued tub job.
3. Gluing your own tubs gives you licence to spout nonsense on online forums and become a valued member of the tub lover society.

You decide.

wilburtrump

what inner tubes do you use with your tubs, john?

Vam Polecat

Is that a trick question Will?

wilburtrump

i was just feeling left out. I've only got one wheel with a tub on.

and i didn't glue it on myself.

:-(

Jane

Really enjoying this tubbies thread ... and no, I haven't the slightest clue

Theo-saurus

you are but butyl using muggles

Vam Polecat

I thought you were poking fun

The inner tubes are sewn up inside the tubs, so in effect you have no influence over what tubes you choose, beyond deciding on a certain brand. Most tubs have latex tubes, but a few manufacturers use butyl - Continental and Tufo spring to mind.
