The only other bikes with that kind of stiffness....was a Parlee Z4/SRAM Red and Storck Fascenario 0.7/Super Record.
You sure about that? Don't lay it on too
I own both bikes and run the Rotor 3D crank on both. I can't tell the difference between the bottom brackets. I actually ride them...not just parking lot test rides or riding a buddy's bike for a quick spin around the block. The S2 just don't bite back when the roads get rough.
Don't get me wrong...I love my System...but its just not the wunder bike you make it out to be.
I mean the S2 worked pretty well for the Test Team in 09...just sayin.
