I added a nylon washer around the stock bolt going into the bars. The arrow mirror is secured to the plastic sleeve. Seems to work and cost less then $2.oo to do both sides.
I mounted up the front 17” wheel without the tone ring, put it in sport mode, turned off the ABS/TC and hooliganism ensued. 😈
All I can say is… Ooh my!
I'm guessing there is some visible thread exposed, but I too would like to know. I have a front 17'' wheel ready to go to the machine shop. Has there been a tone ring adaption part produced yet?
I already have a 17'' rear. I've been running the 17/19 combo for a while. It works, but I think ultimately a 17/17 combo makes the most sense for my riding style on this particular bike.
Cheers!
