Wanted: Single speed spacers

Bump.

I would also like to echo the OP and ask for some rear axle spacers (moving sprocket outwards). I need to make up 20mm (ish), and don't want to flip the chainring onto the inside of the cranks.

You can use a piece of plastic/nylon piping cut to size, it is more that strong enough and available in pretty much any DIY/builders store.

Or if you want the spacers just ask in your local bike shop, they normally have a few in the work shop - and usually give them to you for free.
