Hi Ian,
Thanks for the quick reply!

I doubled checked the numbers and measured seat height. Pad x also went down 10mm (this is to center of pad).

My seat height seems to be high compared to your 750mm number.

Height: 174 cm
Inseam: 85 cm
Pad Y: 655 mm
Pad X: 450 mm
Seat height: 780mm

I'm looking at the Speedmax CF 8 DISC eTap or Speedmax CF SLX 8 DISC Di2 - not sure if it matters.

Thank you,

Derek
