|I was just thinking about some possible upgrades and ways to save money and it got me thinking. What would I REALLY need to upgrade to a triple CR?
Things I'm pretty sure I need:
-Right Crank (w/ appropiate new chain rings)
-Left STI Lever
Things I'm not sure about but (I believe) are included in those "triple upgrade" kits:
-Rear Derailer (Really wondering about this one)
-Left Crank (Pretty sure I don't need this)
-Right STI Lever (Pretty sure on this one too, but not sure)
Basically I was wondering if I could save a little money by buying seperate parts rather than one of those pre-packaged upgrade kits.

The price of buying a right crank and rings separately may be the same or more than mailordering a total crankset. The crank arm angle may not be the same so that might be an issue if its designed to use a longer BB axle. No need to buy a right STI although again the cost of a set is probably not much more. Rear der is a bit tougher. The longer cage on a triple der helps the pick up the slack due to greater range of teeth in front. It might be OK. You could try it and make a determination. You'd probably be better off cost-wise by buying a triple upgrade kit rather than indovidual pieces. Used is another option.

|You don't need a front shifter is yours is triple capable, and 9 speed other than pre 2002 DA were.....A short cage rear derailer works fine with a triple,except that due to limited chain wrap capacity,some of the smaller cogs are not usable when in the granny.No problem,since for many the granny is just bailout.|

|You need a
Crankset (cheaper than right side solo)
rear deraileur (if you don't want to lock up or have chain slack)
You most likely will not need a shifter unless you have Dura Ace or Ultegra.
F.Der is debatable. It will be a liitele wider to prevent chain rub but it is not needed.
You will need to adjuct your f-der lockout screws but that is pretty simple.

|Unfortunately you haven't said what you have now. If you now have a Shimano 9-speed double drive train you will need to change the bottom bracket, crank-set with chain rings, both derailleurs, and add some chain. The shifters are the same except with Dura-Ace, even the Ultegra are the same from double to triple. In my mind the bigger question is why. Best change I ever made was upgrading from a triple to a double.
