Help me with a choice I'm making. Upgrading from Open Pro/Ultegra on a Seven Axiom Ti. 3000mi/yr. recreational rider. My weight is 210lbs (for now-don't we all say that). I want the usual: up hills faster and some more speed on flats. Choice is new 2003 Ksyerium SSC SL with the 2 year Mavic warranty program ($650+8% for the warranty) or Dave Thomas' new SpeedDream model with Arrowhead velocity, White Industry hubs and a new Wheelsmith spoke (XE14A?) (20 front/28 back) for $549. SpeedDream is a bit lighter. But what will I feel in stiffness change from my current wheel and performance? Thanks for the help.
