I need some help I ordered the front sprocket 16t and the rear 42t instead I got a 16t frt and 43t rr does a 108 link chain would be fine or do I have to add a link?

 

it'll still work , just the wheel will be a hair more forward on the adjusters

You should always have a new chain with new sprockets tho' , an old
chain will wear them faster and kinda defeats the purpose

So the chains fairly new too right ??

 

Its about 3 week old.

 

that's more than fine. what sprock is saying is you don't want to put a chain (with a certain wear pattern) on new sprockets, and vice versa. if it's a few weeks old, that's fine. but if you had a chain with 5k miles, you may want to reconsider.


you won't need to add a link. 43t is the stock size. 108 is perfect.
