the reach is 5mm longer. I am sure the Geo will work for many however, personally, I dont think dropping my bars by 15mm (a seat to bar drop totaling 7cms) would work, when I went to RETUL, he said although I am very flexible, power-wise, a larger drop didnt work for me. I think there is a lot of misunderstanding in that a large drop is always beneficial to riders. It may be more aero but if your body geo doesnt produce as much power or you cant ride in that position for a long time, its not a good setup.
