Where can I find a 40mm press-fit BB?
I have encountered this strange bottom bracket standard on German city
bikes and at least one Dutch bike. It features a 70mm wide shell with an unthreaded 40mm bore. But this time the parts I have to work with can't really be repaired or retrofitted, and I need to find a replacement BB unit. If it's for cottered cranks, I can use the same old cranks from the bike. Here's one, out of stock and not in North America in any case: http://www.recumbentparts.com/detail...s-fit-127.html Any other ideas? Chalo |

Our USA supplier has closed but you might try a Dutch or German internet supplier. Although Thun seems to have a good marketing department: http://www.bike-eu.com/news/3426/thu...artridges.html I can't find them on their web page at all nowadays: http://www.thun.de/de/ p.s. It seems more people upload photos of these than sell them: http://www.flickr.com/photos/kuvakke...in/photostream Lou? You there?
