Tossing around the idea of going to a 21" front wheel, just for looks obviously. Im seeing a few wheel sizes so Im unsure which is what I need. Im seeing 21"x2.15 and 21"x3.25. Ill be sticking with 40 or 60 spoke. Which wheel would best suit me or should I say will it make any difference between these 2? Looking at tires for these wheels has be a bit confused to. If any of ya know tire sizes for both these wheels any help is very much appreciated. And I assume I can still use my factory rotors ect?

 

Typical Tire sizing for those wheels:
21 x 2.15: MH90-21(=80/90-21) & 90/90-21
21 x 3.25: 120/70-21

Make sure the wheel is for your FXDC Mid-glide Frontend NOT wide-glide
