hey, whilest browsing ebay i came across a mavic bb that fits euro shells, but doesn't use the threads. it also has a floating spindle (like a bmx bb) so you can spacer it out for perfect chain alignment. http://cgi.ebay.co.uk/Mavic-Bottom-Bracket...1QQcmdZViewItem it requires a special facing of the bb for it to fit, this may be the perfect bb for people who have stripped the thread out of their frames. take a look, if anyone has more info i'd be interested in seeing it. cheers, mat
