Like most riders I use only the three biggest cogs with the inside ring on a triple, so don't worry overmuch about chain drag. It is true I occasionally absent-mindedly shift into the big - big combo. This has never been a problem, except on the tandem, where a combination of very long stay

"Why should the RD care how big a difference you have between rings as long as you stay under the 33 & 28 limitations?" You are absolutely right to ask this. The RD absolutely does not care how much of the 33 teeth of capacity is used up in the front and how much is used up in the back. If yo

A short-cage rear mech won't take up all the slack in the chain when on the small-small combos. With the chain at the correct length to cover being in the big-front-ring/big-rear-cog, you will probably find that it droops when in the small front ring, and, say, the four smallest cogs in the rear
