Also does anyone know where I can get hold of a seat clamp bolt? I bought one but its not a perfect fit..(the original one snapped...)
Uhh... Take it to a different shop. Seat posts come in increments of .2mm for a reason. If you try using the wrong size post you will have problems. Go someplace that will test fit posts and then you can know for sure which one fits.
As far as the clamp, oftentimes a plain nut and bolt will do just fine. If you really want the correct clamp I'd say your best bet is probably ebay.
