Current Projects chat and miscellany

Hi all!
I’m new member and can’t start new tread, so I post my question here.
Desperately need help. I bought Raleigh Wisp bicycle of eBay to convert it SS for my wife, but I’m completely lost as I can’t find any spec on the web and don’t know what sizes I need to buy all beats and pieces. I read that some people done conversions, so may be some one could point me in right direction.
I want to powder coat frame and fork, and get all rest components new (build new set of wheels, new saddle and stem, new breaks and handle bar etc.) Wisp frame size is 18” and wheels perhaps is 24? Not sure.
Many thanks, Russ.

To find out what size wheels you have, look what it says on the tyres.
