Sl2 and sl3 have little in common with sl4 Roubaix
Sl4 Roubaix is basically the bottom half of tarmac sl4 with softer seat stays, taller head tube and slacker/longer geo
the newer Roubaix is a much sharper ride under power and sharper handling whereas the older frames felt pretty spongy / soft and appreciated being wound up to speed rather than hammered
Sl4 Roubaix also not as comfortable, it definitely benefits from the cg-r seat post which it was designed around.
Tarmac sl4 is a sharper handling ride especially hard corners and descent, rapid acceleration, but Roubaix sl4 a very impressive endurance frame with more noticeable race feel than older models
so if you look at the price difference and consider that ill probably ride mainly to work on my road bike and my spare time of a weekend on my HT mtb would you have the tarmac?
