Cheap single speed chainset needed....where to buy?

Sorry to hijack, nearly got 5 posts...Can I change my 52/43 chorus chainset to a single speed? I think I have to get smaller crank bolts dont I? Then set up with 43 tooth and get a single speed freewheel on the back. Where do I get the single speed freewheel from, I can only find shimano on the web, and wonder if there is anything else. DO Maillard do any, that is the blocks I have used before.

Cheers and good luck buying new Ives!

yeah you can, single chainring bolts aint hard to come by http://www.charliethebikemonger.com/userimages/procart4.htm

just a case of moving the ring on the spider to get the best alligment "chain line" if the rear wheel you are using has a screw on cassette rather than a shimano type on it is hard to singlespeed as you have to dish the wheel. often easier to buy a rear wheel with a flip flop hub, you can then put a single freewheel on without any messing.
