Omniums on a Precursa has to really be a labour of love with all sorts of jiggery pokery bracket spacers and some "depressions" on the chain stays .
Having tried it a few times now my view is its not worth the trouble, just use SG75's or DA cranks if you think you will notice any difference over the Sugino messengers or Miche Advanced .
if your looking to buy a 54cm Precursa drop me a pm I have a few surplus ones for disposal .
