Track racing bike-build

If you don't have the resources to measure all these factors under full load full speed conditions to a resolution of 0.1W, you might as well go with aesthetics since they are both good.

That's good to know both are highly considered for track riding and either way they'd be up to the job. On further reading I noticed a few people having chainline problems with the Omniums as the chainring bolts can strike wider chainstays (http://www.lfgss.com/thread29215.html).
