Shimano Ultegra 6600 SL 10 speed mini grouoset in good condition This SuperLight version of the 6600 groupset was designed to bridge the gap between Ultegra and Dura-Ace and was sold in Ice Grey All parts feel excellent mechanically and all barrel adjusters and derailleur adjustment screws turn freely and smoothly. There is some wear from use as shown in the photos The rear derailleur jockey wheels have been removed, cleaned and reinstalled and both now spin great. One uses a ceramic bushing and the other has a sealed cartridge bearing All springs and pivots points feel great Feel free to message with any questions or for more info
