|...I know there are many similar questions/answers already posted, but I did not see the answers I exactly needed, so here goes.
I have vintage 1998 Ultegra group, and want to go from a double chainring to a triple.
1) Can I use the same left shifter?
2) Can I use the same bottom bracket?
|Yes, and no,||TJeanloz|

|You can use the same left shifter.
You will need a new bottom bracket (118mm).
Also, you will need:
Front & Rear derailluer

|...why a new rear derailluer?
PS: thanks for helping, I do my all my own bike maintenance and am not going to be relying a LBS mechanic for these types of questions.

|The double rear derailluer doesn't have a long enough cage (space between the two pulleys) to take up all the slack that would be in the chain in a 30-13 type gear (little front ring, little rear ring).|

|I suspected that, thanks again.
I think maybe I should just get out and ride more!!! When I am riding fairly regularly, the hills don't kill me too bad, but basically all I ride is hills and the folks riding triples are soooo slow, I have to leave them behind because I can't pedal that slow.

|"can't pedal that fast" is what I guess I meant to say :)
You know what I mean...I have to maintain like 8mph on the climbs or I will die! Those guys with triples can move along much slower.
