OK, Ergos, sadly the 9-speed units are 9-speed specific, you can downgrade them to 8 but there isn't much point as the 8sp stuff tends to be cheaper. I do have some 8sp Athena units which I'll be listing on eBay in two days. Alternatively I have another 8sp Record set in the queue. All the gen 1 & 2 stuff is pretty much identical between groupsets, it's only the 9-speed era where they varied quality between levels.
PM me if you want pics & prices etc.
Thanks
