No, you do not need to remove the chain. Like you said, just loosen it up and you should be able to remove it no problem.

pretty sure their will be enough adjustment on your carrier that you'll be fine.I just bought a 13 tooth sprocket to play around with but i haven't installed it yet.I bought a primary drive front 13 tooth sprocket and it came with 2 clips has anyone seen this before?

You're only supposed to get 1 clip. 2 must have been a screw-up.

HOW MUCH WOULD I LOSE IN TOP END WITH A 13T? I KNOW IT WILL BE QUITE A BIT BUT, 10 MPH SEEM REASONABLE OR COULD IT BE MORE.
