I'm not saying it can be flopping all over the place. But chain stretch isn't going to cause your chains to derail if you do exact c-c with Paul's added distance.

100 ratcheted in 2012 when we were climbing the bridge. 6" wheels with 16T sprockets. There were more than a few stupid things going on with that drive, but chain alignment wasn't one of them. The chains were properly tensioned too.

I guess I've been too conservative in my comments. I never intended to scare people off of c-c chain runs completely. I just want to caution teams against betting your season on something that has the potential to fail miserably if you don't know what you're doing.
