+1. It can be shimmed. But why not just get a 25.8mm from the LBS? They are still readily avialable and probably cheaper than shipping from a forum member. Or is this another Canada only deal, like those 11-28T freewheels? My supplier lists 25.8mm posts in steel for $4.00, aluminum for $5.50 and micro-adjust for as little as $8.50.
