Went for a quick test ride yesterday and I'm pleased to say all fingers are intact and I still have all my teeth. There were no accidents at all. But I did go gingerly and will probably continue to until I have built up confidence in them. I can't say I could tell night and day differences though. The wheels seemed more sprightly but I am yet to experience the tubular feel from the tyres. Now I'm thinking about the ride yesterday I'm eager to get out again for a longer ride.

Can anyone answer the original question of how much glue would you expect to use per wheel?

Two schools of thought on pre stretching,one says do it,the other?If it needed doing,the maker would have done it,personally I dont.I use the large tin of continental tyre glue,cleaning myself,the wheel & tyre with lighter fuel.I have fitted eight new tubs in the last month,so my thumbs are a bit sore.
How much glue?Enough to soak the tape on the tyre,but not leave any on the surface,& enough to wet the rim twice.
Glue up the tape on a spare,let it dry,& carry it with you,usually works as a get you home without any further glueing.
Never tried pit stop,can anyone seriously vouch for it?

I'm trying out tubulars. Gluing them onto the rim is something that is going to take practise. Just hope I live long enough to master it. I followed this guide:

http://cnl.salk.edu/~jorge/xfer/TubularTiresAdhesivesandPracticePart1-4.pdf


To summarise:

1. Stretch tyres onto rim and inflate to 100+ psi (140 psi in my case) for 24 hours. I dont do this.

2. Thin layer of mastik one on the tyre backing tape also left for 24 hours. Until dry,maybe an hour or two

3. Thin layer of mastik one on the rim, leave to dry 24 hours. Again,only until dry

4. A second thin layer of mastik one on the rim, leave for 24 hours. Only if the rim was new,or had been cleaned prior to mounting

5. A third thin layer of mastik one one the rim, wait until tacky and mount the tyre. Yes

5. When mounted and straight, firmly press down on the tyre while rolling to push tyre into rim. yes

6. Inflate to maximum and leave to dry for at least 24 hours. Definate NO,it will cause the tyre to roll on the rim,about 60 psi for 24 hrs & then full pressure for another 24 hrs.


I found applying the glue quite difficult. It gets tacky very quickly and to avoid it turning stringy and then lumpy I had to resort to applying more than might have been necessary. So the question is how much would people expect to be used for two tyres? Mastik one comes in 30ml tubes. Is 30ml the most that should be needed for a single 700c 23 mm wheel and tyre? It also made me think once you add the weight of the glue a 250g tubular is no lighter than a 200g clincher + 70g innertube. The rims are certainly lighter though.

My experiences of gluing tubs are a long and distant memory, picking off the glue from your hands for days and all that mess. Something I wouldn't want to repeat.

Why would you even think to use something like Araldite when there are appropriate, specific tubular tyre glues readily available and at a none prohibitive price?

I have a set of carbon wheels waiting for tubs to be glued on, I will be using Jantex tape. A properly done glue job can save a few watts apparently but the convenience of tape wins out for me.

I guess no one has ever tried a two part epoxy resin like Araldite.

You are joking aren't you?

Never used tubs but Michelin Pro 3 light tyres with latex tubes feel pretty good and sound luvverly.

Not very robust for daily use though.

+1 for Pro Race with latex inner tubes. I used Pro Race 3's and I'm using 4s now on the clincher wheels.

My best time-trial wheels are tubs. Just put the glue on thinly and give it time to dry. Take time to adjust a new tub to proper alignment. Your spares should be second-hand as they're easier to fit on the road (won't be as secure but good enough to get you home).
