Conversion to Ultegra 10speed
Yesterday, I was speaking to a bicycle coach who said that the 10sp
Ultegra crankset and BB could be used on a 9sp setup, and vice versa. Sheldon Brown says this: "Note, also that rear derailers do not care how many gears you have. You do not need to have a so-called "10-speed" derailer to use a 10-speed cassette. This is true of all Shimano derailers with the exception of 1996 and earlier (pre-9-speed) Dura-Ace units." at http://sheldonbrown.com/k7.html The same article also says "Also, hubs marked "8-speed, 9-speed or 10-speed will work with any number of sprockets! (Add a 4.5 mm spacer before installing a 7-speed cassette on an 8-, 9-, or 10-speed hub.)" However, he then says "2004-2006 Dura-Ace 7800 10 speed hubs only accept Dura-Ace 10 speed cassettes." I've heard that apart from the alloys, Ultegra 10sp is mechanically basically the same as Dura Ace 10, so maybe the same applies to Ultegra. Anyway, it does beg the question, what is the absolute minimum change required to move over from 9sp Ultegra to 10sp Ultegra? Since various places sell groupset bits one piece at a time, bits could be replaced piecemeal as they wear out, rather than all at once so I would have to discard otherwise perfectly servicable bits. Maybe I'm reading the various things wrongly, but would I be right in saying that to convert from 9sp to 10sp I would at minimum only need to repace the casette, STI shifters and chain? That would suit me fine, as my STI shifters are getting to the end of their useful life and the others are considered to be "consumables" anyway. Travis |
