I recently mentioned a new threadless BB design I saw in Taiwan. Much to my surprise a sample arrived today. Usually development on products like this takes a very long time, so I wasn't expecting to get one for many months.
This BB uses a new locking system that works even if the threads in the BB shell are damaged, or non-existent. That means it should fit Swiss and other oddly threaded bikes. As the adjustable cup is tightened the silver sleeve is pushed up the tapered outside face, expanding and locking in the BB. Installation requires a traditional-style BB spanner or a pin wrench.
We're going to try it on a few frames before ordering, but the quality looks great. The bearing are big sealed cartridges with serious weather seals. The body and cup are alloy with nice machining. The axle is chromo steel, but not hollow. As for the colors, we can have that changed; maybe lime green?
If all goes well we should see these arrive in about 3 months. The first shipment will probably be 107mm, 110mm, and 113mm lengths. We don't have final pricing yet, but I would guess they will run around $75.
