Wanted: 700c wheelset, crankset, quill stem converter

Hi, I'm after some parts for a singlespeed build:

• 700c singlespeed wheelset for 126mm rear spacing - up to £75
  
• 1" to 1 1/8" quill stem converter - as cheap as possible!
  
• Crankset to fit square tapered campag. BB - 165-170mm - ideally with a 44/46t chainring.
  
• Adjsutment screws for rear drop outs.
  
  

Items don't have to be anything special to look at - just in good working order to get me started.

I can pick up in and around SW London, and I travel into central London fairly regularly. Otherwise I'd need items posted.

Thanks,

Nick
