I was looking at spacers, i think i need a 4.5mm one for the above, but i thought that it would be likely that this could be bodged. Any experience of this?

thanks

It used to be a standard piece when 8spd hubs first came out.

Your LBS may still have one in the parts bin.

Otherwise try SS spacers.

Try using a sprocket spacer or two, the ones that live between the loose sprockets.

How wide is an old (smallest) sprocket?

>> << About that much? 1.7mm?

£2.99 for a 4.5mm 7 to 8 speed spacer

thanks everyone, i’ll mooch down to my LBS
