Info easily searched for...
You will need a 5mm spacer, the Ex has the larger brakes, the caliper will scrape on the wheel.
I did search, all I found was a bunch of classified listings for hx's on google.
And on this site I just found a bunch of posts asking if they have to roll their fenders with a certain size wheel spacer, or what are wheel spacers.
I did search, thank you very much.
But thanks for the answer
(what's the tech section for? I'm sure any question could be searched down far enough and an answer could be found. If that's the case then why even have a tech section on the site?)
