Crank Help!

£87 ?!?! Watch and wait and just buy the crank arms to save ££s
you should be able to get a slightly more modern pair for £20 if you are patient.
I know your bike is unrideable - but unless you are really want period-correctness, it's a waste of monneys IMO. Those cranks have some real history.
EDIT - you will need a Bottom Bracket aswell.

If you buy me a 111mm campagnolo chorus Bottom bracket I will give you my TA cranks and a bottom bracket. :-) not the chainring.

I'll buy you a Chorus BB, how much? when?
