Strengths:    Light, fast, precise, stiff with linear power transfer and looks very sharp

Weaknesses:    No longer produced

Bottom Line:   
I have the 165mm arms, and they spin up very fast...I simply cannot believe how a 5mm variation can make such a difference in cadence.

At 741g you get Dura Ace shifting efficiency and reliability, thanks in part to the startegically-placed shift pins and ramps. The Hollowtech II cold forged hollow cranks arms and spindle makes this crankset AS GOOD as the pricier Ultegra SL gruppo...who needs more spindle machining and aluminum chainring bolts(the ONLY weight difference)???
