My bike is a Trek 820 (probably 1999) and I ride maybe twice a week. Well I was looking at the original sprockets (Shimano FC-CT92 24/34/42 170) and many where worn. I'm looking to order online and my price range is $20-$80 since I don't ride that much. Well I was looking at Shimano Tourney FC-TX70 and not knowing if it would work or not but the price is right $20.00. I'm thinking it is just as good as the original that lasted 6 plus years, but is there a step better?
Thanks for the feed back!
