I guess your saying you do not have an external threaded BB.
Isn't a Quarq pm mounted in spider of crank?
I have a 2011 Trek Madone w/BB90. I had my SRAM RED Compact Crank (BCD 110) from my old bike (which used a GXP external BB) re-installed to the Madone using required a BB90 BB kit. I chose the Enduro one with hybrid ceramic bearings.
