Thank you for the great information and ideas about the triple! After searching all morning, I have narrowed it down to choosing between a couple of Shimano FC-6206s or Shimano FC-1057s since everything else on the bike is Shimano. Unfortunately, more questions arise. Most of the ones I've seen have no dust caps. Is that a big deal if I can't find a crank with dust caps?
The bottom bracket sizing still confuses me, especially after reading no67el's post. That's great about your daughter, by the way! I thought BBs had to be an exact size to work, but maybe they don't? I have looked at Velobase on the FC-6206 which states a 68mm X 121.5mm BB, but another site says 68 X 122.5. Does Shimano make new BBs to fit the 6206 or 1057? Or, do I need to search for a used one? I'd hate to finally buy something and find out I can't get the proper BB.
Thanks, again!
Brian
