You guys know if it is possible to fit an ISO CR on a JIS fork? The difference I believe is about .4mm. I have heard that you can get away with pressing ISO cups (30.2mm) in JIS headtubes (30.0mm) - though I have no first hand experiences.
Anyone on here try this or have seen it done? I want to fit my Dura Ace HS on my JIS frame/fork.
