Both the CAAD9 and systemsix are renowned for there torsional stiffness. The system being the lighter and more comfortable one. The caad being the cheaper one.kcinjp said:Mind if I ask what kind of wheels you're on? I had a six13 with Mavic equips and SLs and found the bike too plush. The carbon soloist was a league better but not the price, mind you the wheels were different (eastons) too.
I wouldn't mind switching to a CAAD 9 IF it were that much stiffer.
Bike was stolen so I'm off to a fresh start.
Any thoughts for a stiffer ride than six13 appreciated.
