ok, i ride a sm610, have the rear brake adjusted down as far as possible but find it damn hard to use it without taking my whole foot off the peg, especially when wearing my MX boots. this in turn makes it mega hard to modulate the rear brake, and creating the difficulties. i find it hard to do even in shoes unless i'm sitting way back on the seat. its like i need the peg to be a bit higher but dont have any adjustablity that way. i'm 6'1" with 32 inseam. anyone have any suggestions?
