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 |

If this bugs ya, get Campag 10s ERGO levers and any Campag rear derailleur, spend the same $ that you will on ultegra STI, cogset and chain(or less), and go ride... Travis |

Peter Chisholm replied: Right lever, cogset [sic] and chain...minimum to be '10s' ultegra. Peter, Peter, you're usually complete in this sort of thing (even when you use a funny made-up word for "cassette") but you forgot the 4th essential item: Travis will also need new handlebar tape, preferably 10-speed compatible handlebar tape.

Dear BJK, The cut-throat world of mail-order bicycle parts leads to ruthless business decisions that are not immediately obvious to customers. Harris Cyclery already loses money stocking the different kinds of handlebar tape needed for modern Campagnolo and Shimano shifters. Rumor has it that Sheldon may soon stop offering fixed-gear handlebar tape. The shop hasn't sold tublar handlebar tape for years. It's simply impossible to break even if you have to offer handlebar tape for both above and below the seat recumbent handlebars. Cheers, Carl Fogel |

Tape vs. Grips, was Conversion to Ultegra 10speed

Everyone knows recumbent bikes require *grips* to help maintain control at extraordinarily high velocities above 20,000 meters per hour. These are the latest volley in the recumbent technology war: http://www.performancebike.com/shop/....cfm?SKU=20412 Jeff "Hang On Sloopy" Wills |
