Hi, this is my first post to the forum. i currently ride a kona one20 delux from 2008, i bought this bike from a friend who owned a shop. i know nothing about bikes and he said that this one would be able to handle light downhill. im getting pretty alright at biking now and i feel like my bike is holding me back from doing certain terrain here. i mainly ride at park city mountain resort in utah as i work here and get a free pass, occasionally i go to moab to ride. again i know nothing about bikes but when i hop on some of my friends bikes that cost 3-4k i do so much better, so this season im going to be in the market for a nice bike. what are the things i need to look out for? or what is a good stock bike to look for, it doesnt need to be new. if im buying a used bike what sort of things do i need to look at to make sure the bike is in good condition? i do have about 4k i could drop on a bike but would prefer to stay as cheap as i can.
thanks for all the info in advanced
