New Ultegra Group

[rboz2006]

Can anyone tell me what the difference is in the Shimano groups? The new Ultegra SL group lists two rear derailleurs 6600G-GS and 6600G-SS. Same with other components. Just wondering. Thanks.

The 1st G means you're buying an Ice Grey version the silver. The 2nd SS or GS gets you a different pulley cage. SS for a triple, GS for a double.

Long derailleur cage vs short cage, triple vs double.
