I'm wanting to add a 21" wheel to my bike. But being a 1999 king I seem to be having issues. Seems all I look at none of the bolt straight up. Im not sure what I need to make it work. Any help will be appreciated.

 

Did you get an explanation why they won't bolt right up?

Someone can correct me but maybe the 2000+ bikes uses the current wheel bearings. The earlier bikes might be using the Timken bearings. Probably not many wheel mfg may not carry them.

I have the 21" Sinister fat spoke wheel on my '13 King. I would give them a call, as they carry wheels made for the older bikes as well. They also carry the smaller 11.5" rotors for your bike. They also carry tires and install and balance everything.

 

Hi all,
I had a 99 RKC and as I recall they do have the Timken bearings. I changed the lowers which will allow use of newer 1inch axle and dual piston calipers. To the original poster I have an owner's manual for that 99 RK, if interested I'll send it to you for the price of postage.......goldie
