Tubs

I'm gonna say don't glue onto that.

I dont really want to spend a week getting all the old glue off

Why not? What would you do otherwise?! Do people on here also have friends!?

Anyway if its alu you can melt the glue using blowtorch or summin

It's a disc wheel, I wouldn't go near it with a blowtorch. Or any rim for that matter.

I'd pay a junior wrench to get that off for me with the suitable tools and chemicals.

Then I would watch them suffer. HA HA HA HA HA etc.

Why remove old glue it not Ness cary. Remove the big lumps, apply new layer to the rim and new tub leave over night then mount. Leaving over night is my trick to avoid mess and it does not affect the bond.

Mastik is by far the best glue. You also get more in a tin.

So you mount the tyre with the glue dry?

final layer on rim before mounting no?

That's how I do it, but no mention of a final layer in the post. When I have changed a tub on the roadside it's been dry/dry and the tub is "proper on" after a few miles. IMHO anyway, so wondered if cycle clinic was mounting that way.

My paves went on real nice. Probably the alu specific glue. The carbon stuff is pretty viscous.

Going to take the alu tubs climbing tomorrow. It'll be my first ride on alu tubulars. First on a 25mm/27mm tub set too. Shouldbe interesting.

Yes I said apply a new layer to the rim an tub and leave over night for a rim with glue already on it. When the two make contact after mounting, a bond forms. Then inflate to 120 psi and leave overnight. The bond is extremely secure the following day. No mess either.

When mounting on new rim one layer of glue on the rim leave over night then another on the rim and tub and leave over night. Mount the tyre the following morning and inflate to 120 psi. Leave 24 hrs and vulva it's ready to roll. I have had people describe they broke finger nails getting the tub of I have glued. Personally use a tyre lever it's less painful.

The tub has to fit the rim properly though. My latest is vittoria sc tub on old mavics gel 280 rims and there does not fit the rim properly there are gaps at edges. It should be fine though I'll find the hard way if it isn't (it my bike).

When changing a tub at the side of the road I mount a pre glued tub on the rim. By the time I get home the bond is so good I can leave it in place if I want to and have done for months until that tub punctured.

Small fury. Paves are lovely. You will love the ride. I do think the rolling resistance is bit higher on these but you won't notice on a hill as gravity is worse. The grip is superb.

The paves are for grip and robustness.

I have some new challenge criteriums on the aero wheels. Very impressed. Everything you'd want from a set of 'weekend best' tubular.

All the other tub wheels I have either came with none, very little glue leftovers or were taped. So I didn't spend more than 2 nights cleaning the rims but this is new levels. I have a few friends but don't sleep much so yeah..

Judging by the above comments it looks like it could be possible to just glue on top, but there are 'big lumps' all round the rim. I don't like how its uneven in places, bare spots here and there but that would be filled with the new glue right? Anymore opinions? Will decide by tomorrow night either way

Its pretty thick and stuck on so I dont really want to spend a week getting all the old glue off.

A weeks?? couple hours more likely (been doing tubular at work).

The problem is its a disc wheel, so using solvents is a big no and will be more time consuming. What are your methods?

White spirit and careful use of screwdriver.

We also mount it dry too (2 to 3 time applying layer, ditto to tubular).

I tend to sit in front of the telly peeling and chunky bits off untill I get bored.

If you use a softish brush to apply the fresh glue. You'll flatten it out a bit.

The paves were awesome.
I could really feel the extra volume.
I enjoy a good lean so appreciate the excellent roundness too.

Don't lean!

Hmmm.
I did have a slight incident. Over cooked a corner, grabed too much brake considering the alu braking surface, and had to do a few skides to whip the rear around and not go off the road.

Now have 3 slightly bold patches on a tyre from its first use.

Probably not enough leaning.

I find plain old ronsonol to do the trick with removing glue. Still involves a lot of scrubbing work with a nylon brush too though.

After reading a few threads on other sites etc etc calculating the risks.. I believe that it wont make a difference gluing on top seeing as the glue is a contact adhesive and can surely only provide a better grip to the rim. The old glue was still slightly tacky, not dry and falling off so have now applied a fresh coat of glue. Back in the day I can image people re-gluieng tubs on a monthly basis especially those who raced etc. so I highly doubt they would clean the rim often or at all even. The uneven glue wont make much difference I dont think, its less than 1mm so I highly doubt there will be any bumpy parts.

Will do 2 more over the next couple of days then one on the tub and should be alright.

I'd do one coat on the tub. Dry.
Then a coat on the rim just before mounting.

This on a rim with lose bits of glue removed. But otherwise uncleaned. I consider the old glue to act as my first coat.

2 thin coats on rim and one on tub should be more than enough?

That's what I'd do.

Last tub I removed took a couple metal tyre levers.
