How To Convert From Triple to a Double?(6 posts)

How To Convert From Triple to a Double?sidley

I'm building up a new frame with old, mostly, ultregra parts. Presently it has a triple but I want to convert it to a double.

I've been given 2 options. First, the $20 option: take off the third ring and lock out the superfluous gears. Second, the $400 option purchase new BB, R. derail., F. derail., and crankset, and the labor to install that.

Can I get away with the $20 option for a little while?

How about the $0 option; just don't use the third ring.

You really dont need a new crankset.Just remove the granny ring and use the BB for the double crankset.

I'll echo Rusty's comments. Get the BB with a shorter spindle, adust the H & L on the front der, and remove the third chainring.

Question is, why? Mostly flat where you ride? Trying to lighten up the bike?

If you are trying to improve your shifting, removing a chainring and using the stuff you have now isn't going to do it.

If you just want the look of a double, you aren't going to get that either. The guys who care about that sort of thing will spot that long cage derailleur from across the parking lot.

Someone else on this post wants to run a double? My god, lord above, there is someone else.
