I just purchased a Eddy Merckx Team SC (NICE!!!).<br />I live in Canada ,so, winter months i have taken to the indoor trainer. On my trainer (CyclopsFluid2) I ride for 45 minutes, I don't stand out of the saddle because i don't want to stress the frame out. MY problem is with pain in my tailbone, when i ride outside i feel in better position on my bike but i don't change anything, indoors i feel more cramped! I don't feel pain riding out side, indoors i do. Am i riding too long on my trainer or is my positioning wrong. Any help would be grand!!! :-[
