| Chain and Sprockets
This topic has almost certainly been discussed before.
I want to know the general opinion on sprocket sizes for my 748S. Standard is 14/38 and I would like a little more drive. What would be the best combination based on experience? Is it good procedure to replace all sprockets and chain at the same time? Any particular make that would be better in this case and where would be good to buy from? |
