Which Groupset?

Meh - no choice of chains or cassettes..

Campag is already proprietary enough without cutting yourself off from affordable cassettes etc. Personally, I only really want to run one system across all my bikes and until 11 speed trickles down to Veloce etc then I'll be happy* with 10 spd Record and Veloce.

• edit: when I say happy - I mean that I will (of course) continue to moan ad nauseam about it on internet forums whenever a part fails :)
  

You have a point.
Athena does seem a little highbrow for a training bike TBH.

Not really something I'd think about, as the drive chains on my bikes are wildly different anyway.
