Hi, first post on here, hope this is the right subforum....Am looking to buy a hybrid bike to ride the Front Range, with a few jaunts into the hills...anyhow, looking through the used ads for a better value...but the frame sizes as listed are all much smaller than road bikes...I s'pose this is because of the way the top bar(forgive me am a cycling newb) angles down towards the seat post on hybrids...anyhow...thinking about a decent model hybrid I've found, but the frame size is 15'...has 700 wheels though...I am 5 10' and will be riding this bike daily...is this bike definitely too small for me? thx for your comments(and yes I'm being vague on the model in case someone snaps it up haha)

Edit: after looking at a few other bikes I realize that the frames are daramitcally different, so, will just go ahead and say its a 2012 TREK 7.5, which seems to have much more of a slant down to the seat post than other hybrids, thanks again for reading
