Ive just changed my rear sprocket from a 38T to a 40T and have had real trouble getting the correct tension on the chain (its a 520 chain with 94 links) i have no idea how old the chain is but its seen better days thats for sure!!!!It has a couple of tight spots in it and is also i would guess a little stretched, so that has what's made it a B**tard to get it right, i had about 6 attempts and still wasnt happy with it when i put it away
So chaps i think its time for a new chain, the questions are.......
What brand of chain do i go for, AFAM, DID etc?
Also do i stick with a standard 94 link chain or do i go for the 96 link?(i.e will i struggle to get the new 94link chain on with the new gearing setup?)
Its on a 748Bip with 14T front and 40T rear.
Any recommendation's/help would be very much appreciated
