So I found out what was creaking!
The crack is approximately 62.3 mm long. Can't be long before it goes BANG midway home 
I've sured it up with a bit of superglue and will give it a look on Monday to see how it's growing, but I'll let the tyre down a little and ride it gently till a replacement rim arrives and I can fit it.
So what replacement rim? This is my first bike with DT rims and is also my last.
The TK rims are ERTO 622x19 and don't want to go narrower.
I need to use the same spokes - how do I know what rims are a similar enough shape to be ok?
Disk only is OK.
32h.
Rims MUST be silver. Bonus points if I can get an old skool polished finish. If barganacious enough, I could buy two to keep them matching.
I think the obvious answer is Mavic A319, how can I be sure they'll be ok?
Cheers
