help! zeus w/ 35xP1 bb threads

[Charles Taylor]

Hi Everybody,

My zeus has a bad fixed bb cup that I need to remove but don't know the handed-ness of the thread.
The sugino bb cups both say 35xP1, which I've never heard of.

More info:

bb shell is 67mm wide (not 68, measured twice)

Zeus frame looks to be late 70s (cable guides over bb shell)

campy italian Nuovo Record spindle (70-ss) is a perfect replacement for the sugino spindle.

My question is: what's the handed-ness of the fixed cup? It's on there monster tight, maybe
rusted tight.

Thanks

35 x 1 designates both French and Swiss threading, the difference being in the "handedness" of the
fixed cup.

French fixed cups=right (wrong)

Swiss fixed cups=left (right)

I've never heard of Zeus using Swiss, I'd bet it's French, righty-tighty on both sides.

That's French threading.

It'll be right-hand, which is why it needs to be monster-tight.

Zeus bicycles are French thread. Unscrew BB cups anti-clockwise, same on both sides. The shell was
68mm before someone agressively faced the sides. It is still a "68" for purposes of parts selection.

The proper tool bolts through the BB , clamping the cup securely, and has a long 400mm handle. Well
worth the $1 charge at an LBS if it is troublesome at home, IMHO.
