I have compiled some info on this, and especially the 10S narrow casette with "direction" (?), that seems to work with 105, Ultegra and DA. Note: The table is probably very incomplete!

Is that why it breaks so often in bicycle crashes? Only from excessive horsting around. Ba-da-bump. I'll be here all week. Enjoy the salad. |

CN-5700, 6700, 7900 that Shimano has no less than three chains all the same size, only with different quality, and they correspond to their 105, Ultegra and Dura-Ace groups? So at least on this casette, there is no problem in theory mixing components from any of those groups? This brings me the thought, to what extent do these groups differ in technology and to what extent are they the same only with different quality and detail finish to appeal to different economic segments of the cycling world? -- underground experts united http://user.it.uu.se/~embe8573 |

There's one under every rock: http://www.bianchiusa.com/bikes/road...-dura-ace-mix/ This has a "Shimano Ultegra 11sp" chain, I wonder if that is the same as "Shimano Ultegra 6800/XT M8000 HG701 11-Speed Chain" [1]. If "chain width" is the same as "pin length", this one is 5.62mm which means it isn't in my table [1] http://www.chainreactioncycles.com/s.../rp-prod119827 -- underground experts united http://user.it.uu.se/~embe8573 |
