Frame size preference.
If you had to have one or the other would you rather have a frame one size too large or one size too small? You could do anything after to the bike to adjust it except alter the frame.
Still a very limited supply of bike sizes not to mention models. I have a bike, two actually but the wrong sizes, and I should just wait it out until supply catches up to the wait lists but I am not getting any younger.
Thanks in advance, Frank.
