OK, so I forgot to mention to test it in the large/large combo and that there would be someone who wouldn't. You just need to be sure you have the right size ( long enough) derailleur pulley cage.

I've used this technique on HUNDREDS of touring bikes, mountain bikes, road bikes with triples etc. with success in all cases with no damage whatsoever, I have had to reccomend longer reach derailleurs, ( before damage), to those who had tried to use short reach when converting to triples etc.

Note: This technique gives you the MAXIMUM chain length you can use and still have tension on the chain in the small/small combo. This maximum length gives the most flexibilty when using more than one size cassette/freewheel. If it doesn't work for you you will NEED a longer derailleur cage.


Oh, Sheldon- This is a proven technique - Scientific Method and I learned it from a guy who used to work with Albert Eisentraut among others
