Do you think this is bent?

[SeeingisBelievingGTMuseum]

is the chain running over the sideplate finger under the top pulley?

Hi Spibbs Hate to be a fly in this ointment here, but when you re-set your oln you stretch the tubes AND the dropout ie: you reset the angle of the rear stays by 4mm, which alters the angle of the dropout in proportion. YES buddy they run like a *****d when the alignment is out no matter what you do.

No offence, but it sounds like your LBS guy is making beer money from just pulling the stays slightly. Trust me, 4mm can be moved by my 11yr old daughter.

Think about it logically, " mentally pull your stays apart and the angle of the dropout changes too. Now close it down from 130mm to 126mm. This is the precise angle discrepency you are fighting with if you look at the dropout in your pic, its kicked in, just as you'd expect when shortening the oln, outward if its a 126 > 130. Later fellow, yours Laz.

PS: "are those titanium hubs I see ... you lucky man you "

Hey Laz,

thanks for your imput.

when this frame was originally built the oln was 126, last owner had it reset @130 so he could run modern kit- it's now gone back to 126 so it should all true, no?

I watched the guy reset the frame, he used some kind of special tool to check the alignment of the dropouts.

So was it his work or the bike falling over? I'm not sure

Anyways it's going back.

Not titanium hubs, just common or garden shimano 600's

one of these. It measures hanger alignment against the rim position at two points.

gavr, thanks for that.

Yesterday I took it back to the local frame builder who originally did the cold setting for me.

He used a tool like that and another that looked homemade which fitted between the dropouts. It's all straight now and didn't cost a bean

The chain noise is a lot better but still a tad noisy, maybe I'm paranoid about it now.

It's a 5/6 speed uniglide chain, 6 speed uniglide cassette, 600ex sis rear mech (not the tricolor one)...that should all be compatible?

I'm on the lookout for an NOS 13-28 uniglide cassette...(not the ones on ebay in USA that cost $100000000000000000000000000000000's )

I've not read every post on here so if what I'm about to say has been said, my apologies.

Check the jockey wheels, there is a difference between them, upper and lower, just switch them and see if it's quieter.

Hope it helps

Tonight I fitted a new chain, a sram pc-870 and it's LOADS better.

Suprising really as the last one was a NOS uniglide chain of the correct speed for my uniglide cassette....beats me?

Anyway I consider this particular issue SOLVED

thanks for all the advice and suggestions, I have learned much.
