Kalavinka Super Exhibition track bike build

bye

nice frame, shame about the build!

.

That bar angle is a disgrace!

Try here champ. Generally bad from to post your own bike in someone else's project thread.

He/she done removed it :( Was it awful?

It was no oil painting.

So I eventually I bought my vittoria open corsas and attempted to glue them to my wheel. My thinking was to coat the wheel twice with glue and the tire once (having stretched them tire) and to try to fit the tire when the second coat of glue on the rim was wet.

I don't think my stretching was sufficient as when I had to place the tires onto the rim I was really struggling to get the tread of the tire to not be in contact with the glue on the rim and to get the tire the whole way round.
I'd heard of people finding them easy enough to change on the side of the road so I clearly I wasn't doing it right...

Fed up of the tires I then took it to the LBS thinking that I'd practice gluing tubs on some less expensive wheels and tires when I could. It took them a full three longer than they had said, as they were removing glue and at the end came out at £50? I kind of felt mugged off, is that a going price? (though I was more mugged off due to the fact that every week they said they'd need another week and then didn't even email me to tell me it wasn't ready)

They said there was a lot of glue to remove and I am now thinking that they were removing all of the pale beige stuff on the rim (some glue from the Japanese keirin I guess) which I thought wasn't entirely necessary if it were smooth/without anything that would obviously make it hard to place the tire onto.

you can kind of see it in the second picture (should have taken some more specific pictures of it) on the front wheel. But anyway, the wheels were released to me and I went out to get a few pictures or so showing the first properly rideable state of the bike after a full on year pretty much.

Sounds to me like they didn't really know what they were doing. Anyone used to gluing tubs makes it out to be quite a trivial affair once you've got the knack of it. I've only ever used tape and it is genuinely dead easy.

Gluing is easy, I've done it. Fixing at home is easy too.

But I had to ask Le Manfriend with his much larger grip strength to stretch the tubes on. That might be the tricky bit.

I've gone of tubs myself too much glass in Belfast but you can use sealant. Lots of good info in the tubs thread here :)

I've always found tape far less messy than glue.

You're right, one doesn't need to removed ALL the glue, just enough to allow the new glue to be apply.

Secondly, when stretching the tub, usually best to put it on an old clincher rims and let it sit at high pressure, allowing the tub to stretch a bit making installation easier.

There's a whole topic on tubular on this forum, if you're in London, the London Cycle Workshop glue tubular quite regularly last I work there (one or twice a weeks), mainly due to being a Zipp dealership as well as doing track wheels.

In my experience with tubs I've had to stretch them for at least a week, deflating and inflating to max psi throughout. Before starting the glueing process I mount the tyre again, if its still difficult then I stretch it using your feet a la vince - https://www.lfgss.com/conversations/197589/

I've only ever used conti glue and found that you really need to let the glue dry in between coats. It says on the tin its says to let dry for 12 hours but I find its not long enough to dry properly. With my last pair I left them for about a day and a half between initial coats (sunny mid summer weather, next to a window). 2 coats minimum on rim, 1 on tub. Once fully dry I go for a thicker final pre installation coat. The thicker coats help to slide the tub on and not pick up the dried glue.

Mixed fresh coats on old glue once and it was fine. For peace of mind the next tubs I did I spent the evening getting rid of all the old glue.

This is a bit late but its just my 2p incase you do some in the future :-)

You're right, it does need to be hung up to dry, usually glued in the morning then leave it until the next day.

Had been putting off replying to all of y'all, and forgot.

Definitely wouldn't put it past them, though I rekon (/had thought) they had to remove all of the old Japanese glue. Which I can understand taking a while.

^^^^^ @JWestland

to stretch the tubes on. That might be the tricky bit.

Yeah, definitely struggled with that bit - DESPITE MY MASSIVE STRENGTH, don't get me wrong.
I had got them on to the wheels before without any glue and did manage to get them on the rim, just the last bit to go on was the wrong orientation. Think I left them too long after stretching (> month) such that it ha no affect.

I've gone of tubs myself too much glass in Belfast but you can use sealant

Yeah, don't think tubs will be my first choice.

^^^^ @dallas

Yeah, understandable. Wanted to do these ones proper, that said I would probably use tape from now on (had heard of some off reviews on them though), if only I had not failed to put these on myself.

Glad to hear it, though maybe my judgement of the surface was off.

Secondly, when stretching the tub, usually best to put it on an old clincher rims and let it sit at high pressure, allowing the tub to stretch a bit making installation easier.

Yeah, will be putting them on a rim at higher pressures closer to the time of installation than this attempt.

if you're in London

Am not in London but the wonderfully flat city of Cambridge.

Yeah, that sounds like a much better way of doing it. I left mine to dry for 24 hrs (Conti too), they did feel a bit sticky. My final layer (2nd on rim) was a bit thin and had somewhat dried by the time the tire was on, wasn't helpful. Didn't really know how much glue to buy before hand, only had 50g, didn't finish it either.
Very appreciated 2p.

Thanks to all the advice.
