Tubs

No but I've used vittoria pit stop and it got me home last time.

pls halp! came back for a ride today and noticed a small cut in the sidewall of one of my tubs, and the tube poking out by a few mm.

tried sticking a patch over that bit, which helped, but the tubes still poking out a bit. how likely am i to kill myself riding on it for a couple more days? (got a ~140km left for my festive 500) I have no idea what i'm doing with tubs and i don't have another to fit unfortunately

You can't "stick a path" over it. You can boot it from the inside and use latex milk to keep the fibres down. I'd typically view the tyre as spent and keep it for spare materials-- such as boots.

If it is the front it is quite dangerous since it'll probably blow and you can loose control.. Rear.. It'll just blow.. not saying you can't loose control but generally...

Fair enough, I was hoping I might be able to bodge fix it for a few more rides but sounds like a faff to sort. sounds like I was pretty fortunate it didn't burst on my way home today. Luckily it's the front, so I can grab the wheel from my fixed gear to finish!

Anyone got any recommendations for LBS's east ish for fitting tubs? If not I'll just bite the bullet and get learning!

Think about it, would you be comfortable riding at 20mph with a bit of inner tube sticking out?

Getting them on isn't the problem, it's getting them off.

Its a dead tub. First you need to find an lbs with tubs in stock.

You should have at least one spare tub preglued which you carry with you. You then fot that tub in emergancies. You should be gluing your tubs with vitoria mastik one and a tick layer on the rim and one the tub. So when you remove a dead tub enough glue is left behind that you can mount the preglued spare (it has a good layer of glue one it) and then inflate and the bond will be very secure.

nooope, no idea how far i rode today like that! the cut was actually very small when deflated, so tried my hand at some superglueing given i'll replace it anyway, which has held together when re-inflating, but i don't really trust it - i'll swap to a front clincher tomorrow.

yeahhh to be honest i really don't fancy doing that roadside, so i've just got a can of pit stop, some super glue, rubber patches and hopes and dreams (a credit card for a taxi to the nearest station)

Sorry it not hard. You pull the old tub off and mojnt the fresh one. Your done in the time it take to replace an inner tube. If you cant do this at the road side you will end up stranded and you should probably stick to clinchers as pit stop does not always work and patches well you cant a punctured tub at the roadside and you cant do it at home unless you take the thb apart and pull the the out.

If you ride with tubs like i do have a spare tub in your back pocket. I dont even bother withstop any more. Expensive and if i want to be parnoid i will carry two spare tubs.

The best and most convienient local bicycle mechanic can be YOU. Learn! With a little bit of experience you'll be much better than the majority of bicycle shops..

If you use Tufo tape you'll probably be able to get it on and inflated quicker than a clincher.

Thirded for gluing tubs yourself, It's not hard after a bit of practice. I quite enjoy gluing up a set of tubs now. Likewise easy for putting on pre-glued tub at the roadside for punctures

So old school glue or tufo tape?

Glue.

Glue - it's easier than tape in my view.

Takes 1o minutes per wheel with glue to glue. 5 mknutes applying glue to the rim, 5 minutes to the tub. Leave over night. Mount and inflate. Getting the tub straight can take a bit of time sometimes. If the layer of glue is thick enough and uniform the bond will be very strong. Leaving overnight means the glue will be dry and wont leave a mess on you, the sidewalls or the brake track for you to clean up.

Ta for this, last glued tubs 20+ years ago so bit rusty

The other reason for a good thick layer is when pulling a tub off so much glue is left behind that the preglued spare get a good strong bond instantly. Downside on my hed rims i have to carry a tyre lever to ease the tub off. Even more diffiult getting my mtb tubs which i ride all the time of my 27mm wode carbon rims. Fortunatley the geax saguaro's are very robust tyres.

Tufo tape - if you want security and the ease of getting it on and straight.

Glue - if you wan the ability to change it on the side of the road.

For me - tubs for racing, clinchers for everything else.

loving this thread. just got a set of zipp's that will be rebuilt by strada and then have some new rubber put on. currently torn between vittoria corsa g+ or tried and tested gatorskins. I shall be glueing them now as a result

Surley writing thc word in this thread means a penalty.

What about the conti comps more grips than the gatorskins but not as comfortable as the vittoria's. Also the 22mm gp4000sII tubs are very reliable. I am going to have to try a set of dugasts next though. Been using there mtb tubsnon and off for a while. I need to ride more.

Why do your zipps need to be rebuilt?

mtb tubs

Now that's pro

I am not a pro. The geax saguro tubulars 29x2.0" i have mounted to one mtb are the best mtb tyres i have ever tried. The rear has about 3000km on it and has never punctured. I punctured the front once but pitstop sealed it. Then i pinched flatted that tub 30 miles from home so i rode home on a flat tub. The rim (carbon) was fine, even managed about 12mph average. The replacement geax tub is doing sterling service. The dugast tubs are similarly good. All the tubeless mtb tyres i have tried are o.k but these tubs simply excell so why not use them, especially when you can ride on a flat one with no bother. Been using the geax tubs for years got a couple of 26" tyres, i used those when i rode 26" wheeled bikes. They also never punctured.
Just waiting on a set of dugasts new enrst ori tubulars. I have a pair on order due in march though. These are tubeless tubular mtb tyres. Thats the holy grail. They need to make a road version now.
