Hi all,
I'm going to be purchasing an 11-28 cassette for my bike, which will replace the original 11-25. I'm doing this as a bit of extra insurance to help get me to the top of Mont Ventoux in a few months time, but would appreciate some advice from the learned folk on here as to whether a new chain will be required too.
The chain that is currently on the bike is fairly new, and has only covered about 200 miles, so meshing with the new cassette shouldn't be an issue, but are the extra three teeth on the large sprocket likely to cause a problem?
The rear mech is a Shimano Sora, with what I believe is a long cage (about 73mm centre to centre of jockey wheel pins. Chainset is a 50-34
I know a new chain won't break the bank, but don't want to purchase one if there really isn't any need.
Thanks in advance for any advice you guys might be able to give.
