i think it's from the nob thing on my bike. since it was a geared bike haha man they just started appearing today... i need to admit, my bf has been beating me up a little too...
lol same thing happened from my univega conversion. my legs had nasty bruises. but they'll callus and explode. lol jk. put some bar tape over there or a bandana it'll work as a buffer for not so sharp cuts later down the road (like i had).
