• Hey people, thanks so much for your help here, it is most appreciated!

    MA3K and hippy - I'm now sure I need to do something about the dodgy chainset, thanks so much for probably saving my life! Any suggestions for a good conversion, or will most work?

    On the pic hippy (and thanks for the jargon heads up, new to these forum thingys!) The bike is at a mate's at the moment, but will send photos when I get it back over the weekend, although I'm pretty sure it is just a really bad made bit of kit and was meant to be round - the crank and cog is all one piece of pressed steel by the looks of things.

    Pip - think you might have saved my hubs with your advice, thanks v much! Must admit I was going for a cheapy lock ring but will invest in a good'un on your advice. Got a surly cog which seems to be well made. By installing well, I take it you mean greasing the threads and tightening with the proper tools? I think it will be a while (if ever!) before I get skidding and skipping, so hopefully get some life out of the wheels (if they ever turn up..!)
