Guys,
I have been offering some Biopace rings here for weeks, waiting for this type of posting to come along.
Biopace were for 7-speed, so use a 3/32″ chain.
They were without pins and ramps, so could be put on ‘inside-out’ and rotated one hole to give the ‘power’ position mentioned above.
I have the following items that are still up for grabs:
LX M500 crankset, 170mm Square Taper, with 48T Alloy Biopace, 38T Alloy Biopace and 24T Steel Round all on 110/74mm BCD, very nearly new.
Silver 48T steel Biopace 110mm ring
Black 48T steel Biopace 110mm ring
Black 38T steel Biopace 110mm ring
Black 28T steel Biopace 74mm ring
Silver 28T steel Biopace 74mm ring
Mail me for more details if interested.
