But, spend a few minutes making sure the fit is right first.
I found a great deal on a bike on-line, but spent between 5 and 10 minutes checking frame measurements carefully to make sure that the fit was right.
Then bought it immediately after I was certain that it would only need a new stem.
Am very happy with that bike. But if it did not fit well, would not have been very happy.
