I didn't use this for my project. It's a new YST threadless sealed-bearing bottom bracket. 113mm JIS spindle. It's supposedly for 68mm shells, but seems to fit 70mm fine, too. Perhaps an inner ring would be too close to chainstay on some Italian frames. Anyway, this would solve any type of bottom bracket shell thread problem; stripped, English, French, Swiss, Raleigh 26tpi, maybe Italian. $15 shipped to CR members.
