A guy I bought a bike from gave me a square taper titanium bottom bracket spindle from a sealed bottom bracket (I assume it was sealed because the spindle has no cones, only a small lip on one side and a pair of recessed rings around the other that look like they would hold a circlip or snap ring). The spindle has no makers mark but its brand new, light as hell, has the right taper for my cranks and is the right length for my chainline.
My question is: is it possible to use this spindle? can I build a sealed bearing bottom bracket? I have an older shimano UN-51 with the right threads for my bike... could I rip it apart and rebuild it using this titanium spindle?
As always, any and all advice is appreciated!
