Arse, I passed over SB's sizing chart and went strait to the part about whacking it with a hammer! 27.0 seems likely, since most other parts that were on the frame were JIS rather than ISO. Humph... is there any reasonable way to get the crown race on (filing?) or do I just have to bite the bullet and get a new headset (the head-tube races are already pressed in)?
