Well I have learned that the specifications provided with a bike are just enough to drive a person crazy. I have a Fuji '06 Crosstown 1.0 with a SR Suntour NCX-410 28-38-48 that has a four hole 58mm BCD inner chainring. I want to go to a 22t for a 1/4 mi. killer hill on my home commute (yes, I am out of shape but probably is as good of shape as I am going to get on my now 7.5 and soon to be 2 mi. commute).
The 28t ring has a 5mm dish and the few 22t rings I find listed are all flat (uh, as is the 64mm BCD 22t ring I now have, but a cheap lesson as lesson's go). Should I ditch the whole thing? If so, recommendations? It has been a trip learning about the Suntour label, the square Shimano (or Shimano type) spindles, and the odd MTB I assume (left over parts??) 58mm BCD inner ring. Hybrid as specified . . .
