|Changing Ultegra double to Ultegra Triple?||coifmo|
Jul 28, 2003 9:40 AM
|Looking at a nice price on a NOS '02 Lemond Buenos Aires for The Girl, who would like a triple instead of a double.
Shop says no problem.
How hard (or time consuming) is the change-out -- does the BB stay the same? The shift lever? Front deraileur?

|bb, cranks, front derailleur change. i think (not sure) the shifters are universal double/triple.
however, IME most shop/stock bikes/kits come with a 12-25 cassette. you could easily change the cassette to -32 or -34 with a mtb rear (xt = ultegra) and get almost the same low gearing as with triple/12-27.
30/27 = 29.6 gear inches
39/34 = 30.5
something to ponder.

|Yes, but the big gaps between the gears would be annoying.|

|I swapped my Ultegra triple for a double. I traded up for DA, so after I got the new parts (crank, crank arms, BB, fr der.) and had them installed, I think it cost about $300. Maybe you just want to move into the next price range rather than modify this one.
Also, once the wrench adjusts the shifters for a dbl, actual shifting and feel of the STI will be a little bit sloppy.
PS - don't use DA BB they are extremely delicate

|They'll need to change the crank-set, bottom bracket, both derailleurs, and adjust the chain length. Ultegra shifters are the same, double or triple. Consider switching the cassette to a 12-27 instead of the 12-25, depending on the hills you plan to ride.
