Tubs

If it ain't broke don't fix it.
If it's comfort you want go 25c all round.

Was sipping strong Belgium beer while putting the order together. Now have two FMB Paris roubaix coming and no money.
Went with 25s though. Cheers

Excellent choice. Right now the absolute best old school pavé tyre being made. A more suitable drink to the FMBs would be cidre (Bretagne is more cidre than beer country)...

Finally making the transitions to tubs on the road bike, picking a pair of wheels up today! Much excite.

If I can't find a wheelbag, has anyone got some worn out tubs that still hold air that I can use to protect the rims in transit?

I have clinchers atm and I carry 2x tubes; patches and glue; tyre levers etc. on a ride. What is the tub equivalent of that? I am considering tubs just want to know what happens when i puncture middle of nowhere; what would I have to carry and what is the procedure?

All that infos is in the thread bro

But just for you:

Quality tyre leavers (plastic), spare pre-glued tub, folded. Can of pit-stop or equivalent sealant if you believe in it. Needle, thread, patch repair kit, glue if you have the mad-skills.

Spare tub: remove punctured tub, apply new tub, inflate, ride on, but go easy on the bends. OR try sealant, first. You may get lucky.

Repair a tub by the roadside. Some details

Although I'm sure Edwardz will link to the definitive repair guide.

My slight variation would be:

Tyre levers (although I've pulled every tub I've changed by the side of the road off the rim by hand), and a valve extender tool/valve core tool, plus a pre-glued spare tub.

I put sealant in the tyres after fitting them- if you have a flat then the hole is too large for the sealant to cope with (I had a lot of punctures I only knew about when I got to where I was going), so pull that tyre off and change it rather than dicking around with more sealant.

I'd agree with this - whether you have sealant in the tub or not. I'd rather repair a tub at home than dick about with sealant by the roadside that might not work and could do the tub more harm than good.

Got it; does the pre-glued tub holds its sticky property even when folded?

Tub glue is an impact adhesive, so the glue will be dry to touch, but once you've mounted the tub and pumped it up, the bond will form.

Has anyone else had the problem of a valve extender (which works without removing the core) not fitting through the rim?

If so, is there a recommendation for a skinny valve extender? I have borrowed unidentified ones which work, but mine is too fat.

Drill the rim out?

I've done this for tubless Conversions, where you need the thicker valve type.

As for carrying stuff when on tubs. I dont currently own a spare. So I just carry canned sealant. For longer rides I'm planning on taking some latex friendly sealant, and a spare tub.

I'm not really keen on the idea of taking a lovely brand New tubular and filling it With sealant.

I don't use sealant with the nice tubs, the Gators get a good does though.

If find that the sealant needs a puncture layer to hold the tyre together in order to be effective, also.

I cycled alone up a desserted Dalsnibbe yesterday. Carrying just 750ml of water, an energy gel, and a packable Wind jacket for the descent.

So probably not the best person to take advice from.

^ what could go wrong?

Are 21mm tubs alright for racing crits on?

I've always ridden 23mm clinchers but this seems excessively narrow.

Planet X have only have 21mm in these, which I'm sure I've read in reviews are nice. Thoughts?

Cant really comment on crits. But 21mm is fine, so long as you arent too Heavy and require loads of pressure. I have some veloflex 20mm and they feel real fast and grippy.

Looks like I'm gonna have to get a tubular wheelset. 7600 with Araya gold rims used are pretty cheap here.

Seems like for the street, gatorskins are the best tubular to go with.

Thoughts?

I've ridden a gatorskin tub for around 600 miles on the street, after a couple of wet 60 mile rides early on it cut up pretty badly but never punctured. If I were buying a tougher tub I'd probably try the durano T.

For out and out toughness I'd get a Durano HT. Not cheap. But in my experiance Schwalbe do best work horse tyres.

I'm with SF actually, I think that's the one I meant.

Did'nt see you mention the Durano.

My mates on the new fancey 'The One' tubs. Seem to be more resiliant for him than the standard veloflexs he was using. While having similar weight and grip. I still think Veloflex is a no brainer up here. Performance orientated for the clean roads, and unbeatable wet grip for the shite climate. But these Things are personal I guess. My FMBs are still on back order. But after last Nights ride I think a 25mm on the front is a good idea for the endurance stuff I have planned.

What are people using for spare tubs? I got a Vredestein Freccia Pro Tricomp for cheap and it's an improvement on the Sprinters for portability, but I could do with something that rolls up even smaller. Only requirement is removable valve core.

Also, will bunging in 30ml of Stans in a Sprinter make them ride like shit if I have to fix a flat?

I have not noticed any difference in ride quality in tubs pre and post sealant.

I'm ordering some New tubs. Mainly for a 550km sportive.

I currently run, and very much enjoy,
Veloflex Carbon 23mm - rear
Veloflex Extreme 22mm - front

For more comfort, I was thinking of going......
Veloflex Ardenberg 25mm - rear
Veloflex Carbon 23mm - front

But for a little less, I could try....
Dugast Strada 25mm - rear
Dugast Strada 22mm - front

Was sipping strong Belgium beer while putting the order together. Now have two 25mm FMB Paris roubaix coming and no money.

So the Paris Roubaix have been on order for ages. Which is good, as I couldnt afford to pay for them anyway. Box turns up today and it contains a FMB labelled 'Paris Roubaix 25', and another labelled simply Competition CX. I was disapointed at first. As I understood it the CX is standard road tubular which comes in a smaller size, and with less robustness.

A quick check of the shop web site shows they only stock the 22.5mm silk Competition CX. At over £100!. Result.

So now it looks like it'll be.

FMB Paris Roubiax 25mm - rear
FMB Competition CX 22.5mm - front

The only downside is that the PB is stamped may 13 - 2014. So not exactly aged. The CX is 11 months old. So I may have to save them.
