OK. The cassette is a 13-24 (I believe) Hyperglide. The crankset is an older RSX triple without the little ring currently attached. The derailleur is also older RSX, long cage.

So what I'm hearing is that if I use this method, I won't be able to cross-chain. I mean, I know it wears things down faster, but this is my brother's bike. He sometimes does the cross-chain thing before settling into a better gear. The chain I'm using is an SRAM one with a Powerlink. I figured in the video he would just be using a pin, and I would actually cut the chain before that outer link he pointed to. Eliminate that link, and the Powerlink pops in as its substitute offering the same length. But are you guys saying I should cut at the end of the next inner link in order to have adequate chain length?
