Rotor mounting bolts/nuts

anyone know the correct size?  Do they need to be harder than hardware store nuts/bolts? 

I would make sure they're hardened. If you can get Class 10.9 flat head cap screws at the hardware store then those should be fine. The nuts are low profile lock nuts though. Probably not something you will find at the hardware store.

 

I will get back to you on size...

M8 x 32mm with a flat washer and the low profile lock nut.

 

The low profile nuts are't a necessity on the 400, I was thinking of my CR wheels. With a standard lock nut I'd go with 35mm long bolts.

 Didn't think to mention it but it IS a CR front end!  Whew, thanks!

I had a total brain fart. I was looking at the sprocket mounting bolts. :o

99% sure the front rotor mounting bolts are M6 low profile hex bolts. I doubt you will find them at a hardware store.
