Hi. I just picked up a Vuma quad....I am going to put it on my Trek, BSA English threaded.
Hoping someone could tell me the lightest BB I could get.

Zipp Vuma ceramic BB is truly amazing. Light, spins forever and really durable. I've been using it to use my PF30 Quarq's on frames that are BSA or ITL treads.

fwiw, mine weights 550g alltogether (172.5, 50/34, incl. standard (=non-ceramic) bsa bottom bracket)

Mine weighs 544grms including the bb it came with, I just picked up a new Vuma ceramic BB which should drop the weight some more plus I'm going to put Fibre lyte chainrings and sand the graphics off and see if I can drop some weight with chain ring bolts.

Its going on my WW Trek. But Im going to get a new titanium shell fitted in the frame first before I put the Vuma on and I wont do this until my Guru is up and running ....slowly but surely.
