still cant get an answer lol ive measured the bar and I get 20mm yet most of my online searchs suggest 19mm.. I found a supplier that states 19mm. ive been told 21mm by above.
my 20mm measurement is on the original bar but that may have a slight build up of grime over time I don't know. I cleaned where I measured but who knows.
