Wheel standards - please educate me
Could you guys give me a run through of the fundamentals of 20" wheel standards & compatibility? How many axle diameter and lengths are in use? Do most fork dropouts accomodate BMX size axles, or is it only BMX forks that have big enough dropouts? How many hub width standards are in use? And am I right in thinking that the 451 size rim is generally not in use in current folders?
