If I understand your question correctly the reforms make new units available to the Romans.

You no longer can make Veletes, Equites, Hastadi or Principes. After the reforms you can make:

Auxilia (light spearmen)
Early Legionary Cohort (light infantry)
Legionary Cohorts (heavy infantry )
Preatorian Cohorts (heavier infatry)
Urban Cohorts (very heavy infantry)

You get better archers, a new light cavalry and a pretty good heavy cavalry (2 turn production time) and some special units.
