Otherwise... you may want to ask this on the "road cycling" forum and not the "road bike racing" forum... just a suggestion.
One does not want a 60-11 ratio on a road bike. First that would give a top gear of 147 gear inches.
With a cadence of 90 you'd be travelling 39 mph, the areo drag at those speeds would require a rider to produce 1200-1400 watts, something only the elite echolon of cyclist can maintain in only a short burst.
With a 60T ring, your shifting would be a lot rougher since the standard fder arcs are optimized for big rings about 53T.
