Change from Double to Triple(4 posts)

Change from Double to TripleOkiBama

I have a Ultegra Crank w/ a double chainring. How can I change to a triple? Can I just buy the smallest ring, or do I have to change out the entire crank? Also what other adjustments have to be made by the LBS, and do I have to change the shifters?

Thanks

Crank,BB, probably front derailer. Rear derailer will work but may not wrap all the chain when in the granny ring and small cogs.Just avoid that combination.Assuming 9 speeed ultegra,the front shifter shifts a double or triple.

You also need a wider bb to accomodate the three rings.

I am trying to swap my 105 triple for a double, check my ad in the classifieds (cranksets #22) shoot me an email if you are interested. Cheers,

Might want to try a huge cassette in the back instead? -nmfiltersweep
