  • Is using an SP PD-8 on a 20" wheel likely to cause issues? I note that they do a small wheel version, but I don't already own it.

  • I doubt it, since it'll just be like riding it on a big wheel at high speed all the time, but I don't exactly know

    Unless there's some consideration wrt spoke angles and hub flanges and other such mechanical magic

  • As aliasalias said it's just spinning faster. So if anything you could use the less powerful variant (SD-8 I think) which is slightly lighter and has slightly less drag. Small wheel variants are probably in the same vein (or are actually SD-8). But otherwise PD-8 should be fine if you have one already.

  • i have this setup in my soma tradesman since 2016, no issues.

    produces light with less effort than with 650b/700c wheel.
