Hi guys! Ive been riding for 7 years(attakwas,sani,w2w,K2c,oyster,3 towers) Currently on a niner jet nine (large) What bothers me is my high seatpost and Ithink switching to an XL could solve the problem???????? curently using normal seatpost at 78cm and a 90mm stem. Has anyone made the switch? I am 1.84 tall and greater trochanter 101cm arm 84cm Would appreciate help? Do you guys think I will be more stable running a XL? Still want to compete and improve my times Thanks
