I can get a front Hubsmith wheel and a Hubsmith XDR freehub in my country, but the rear wheel is oddly unavailable. This led me down the path to custom build. I am really disappointed to hear that the front wheel is non-standard. The reliability of a big name like Hope or DT Swiss is important to me, and mismatched front and rear hubs is a no go. Would you happen to know of any other manufacturers for a matching front and rear hub using XDR freehub?

glye, thanks for the book recommendation. I'm not ready to build anything myself, and I look forward to learning more!

Another question, is there anything special about the brake calipers? Assuming the caliper is compatible with the rotor size, can road or mountain calipers be directly swapped? Looking at SRAM 2 piston mountain at the moment.

Thanks for all this information. What a great asset you guys are here.
