If it is the Callas from South Korea, I wouldn't put much time or especially money towards it, if it is something nicer than you could but first figure out what is wrong with the current cranks. A two teeth difference for two chainrings on a triple isn't a huge enough need to swap over at least not for me.
Thanks for your reply. Current crank is rusted but still works. I'm currently station in Seoul South Korea at Camp Humprey's (US Army Base) so buying parts here isn't that simple. Mostly over-sea's shipping so I could only find 24/34/42 local shopping. Since it's a cheap bike, your right, not worth the money to buy all new matching expensive parts.
So the two teeth difference shouldn't be a problem once I order the new parts right? Problem meaning when I change gears, etc. I'm newbie to fixing up the bike & since its a cheap bike, not worth to take it to bicycle store since they over-charge.
Thanks again for the helpful info!
