improper fit? google jim langley bike fit. it'll give you an idea of how properly fit your bike is. you could also get a LBS bike fitting but you'll have to keep adjusting your settings to your liking til you find the sweet spot and you'd have to ride maybe 25 to 50 miles to feel if the bike feels good to you. trust me, there is a setting for your body. just keep experimenting. is your saddle high enough? are the bars lower than the saddle?
