So a whole crankset it is ... (I really have no choice: the middle CR is missing several teeth, and inner and outer have a few missing as well). Okay, so say I can't find a used OEM off eBay ... and since I'm no loger using the GF as a Mntn Bike (but as a Utility or Hybrid bicycle instead) ... what are the best NEW options? How about these:
Sugino Impel Triple Crankset
$41.25
or how about...
FSA Dynadrive SQ Taper C-Set Crankset
$50.00
Hint: I want to remain a cheapskate with the replacement crankset
