I'm converting another project and I once again turn to the forum for opinions. I am converting another road bike to a three speed. I am considering either running a RD with three cogs in back and a single ring up front, or three chainrings up front (the current crankset has bolt holes for a triple) and something like the Paul Melvin, Problem Solvers, or Shimano Alfine for the rear:
If I go the RD route, I will just use a regular 8 speed shifter and adjust the lower and upper limit screws (longer screws) to keep the RD from over shifting. If I go the triple chainring route (trying to mainting about a 4 tooth difference between rings) I will just use a regular mtb style front shifter. Please let me know your opinions on what you would do and why. If I am missing something mechanically that won't work, please let me know. Thanks.
I prefer the 1 by 3 that uses a standard dérailleur and shifter as you will have more options for selecting gearing steps than you will running a triple with a tensioner and will also save a good deal of weight and money.
