Not sure why I have all these (and more!). Various biopace rings all in good condition with little wear. 110/74 bcd.
1. 28 inners x 3 all alloy = £3ea
2. 38 middle x 2 all alloy = £4ea
3. 48 outer alloy (marked) = £4
4. 48/38 steel = £6 pr

I also have a set (48/38/2:cool: of the very rare alloy Stronglight version of Biopace called Biostrong (?). Pic to follow but very nice condition and £12. Post at cost, prob £2 max per item.

Re:

Yep, the outer would fit ok on your Tiagra chainset. And a close up of the two steel rings is below. I do have more Biopace including a set of Stronglight version (but please don’t ask why!,)

thanks for the quick reply.
i'm looking at a sort of super compact double set up on my tiagra - do you have any small inners that would also fit my tiagra?

Can i buy both 48 outers with postage? i can paypal no probs.
 
I can let you have the Stronglight set (48/38/2:cool: for £12 plus £3 post. And the steel ones as well for £6 plus £3 post. Let me know!
