    Two Options for Americano Rebuild - Please Help Me Choose!

    After 35k miles of loaded asphalt road touring I want to rebuild my Americano http://www.co-motion.com/single_bikes/americano.html. When I bought it in 2006 it had Ultegra STI's (9 sp) and short-pull Road BB7's, both of which I have been happy with.

    But in 2010, the only new Shimano STI 9 speed is the Sora model and I would prefer to stay with "Ultegra grade" components. Soooo, I see two main options:

    Option 1 ($1100): - Double 10 sp w/ STI's (20-96 gear inches)

    Shimano Ultegra ST-6700 Double STI Lever Set (10 sp)
    Shimano Deore XT FD-M770-10 Dyna-Sys Triple/Double Front Derailleur
    Shimano SLX RD-M663-SGS Dyna-Sys Rear Derailleur (10 sp) (would prefer XT when/if available)
    KMC SS 10 sp chain
    Shimano Deore XT CS-M771-10 Dyna-Sys 10-speed Cassette (11-36)
    SRAM X.9 2X10 Crankset (26-39)
    Avid BB7 Road Disc Brakes

    Of course as a variant to option 1, I could also go with a triple for more gear-inches (need different front der).


    Option 2 ($900): - Triple 9 sp with Thumbies (18-104 gear inches)

    Paul Thumbies Road Shifter
    Shimano Dura-Ace® SL-BS77 Bar-end Shifters
    Shimano® R600 Road Brake Levers
    Shimano XT® M771 Traditional Front Derailleur (9 sp)
    Shimano XT® M772 Shadow Rear Derailleur (9 sp)
    KMC SS 9 sp chain
    Shimano SLX® HG61 Cassette (12-36)
    RaceFace Deus Crankset (46-34-24)
    Avid BB7 Road Disc Brakes

    I use this bike for touring on anything down to and including degraded chip seal. Front and rear panniers with 40 to 50 lbs of gear. Total weight bike, gear and rider 250-260 lbs.

    My considerations include durability and ergonomics. Cost is secondary.

    What do you think?

    Rohloff retrofit kit, Schmidt or Shimano Alfine disc-dynamo front hub..

    Several solutions for fitting the grip shifter on the side of the steer tube

    Hub bub bar end adapter work fine [ fitted into a Drop in bar , IMHO near ideal ]

    According to Shimano, Dyna-Sys derailleurs are only compatible with the new Dyna-Sys shifters...which are flatbar only.

    145mm dropouts preclude a non-McGuyver Rohloff installation. Granted a Rohloff could be incrementally superior to a derailleur system, my application does not (IMHO) warrant the certain $900 incrementally higher cost. (Maybe if I was also going to be replacing the rear hub... humm...) I rarely ride at night so the dynohub would be wasted on me.

    I was afraid of this. Manufacturers, be they of bike components or electronics, seem not to consider compatability with their older products. Touring bikes are the bastards of the bike world and do not seem to warrant purpose-built componetry.

    Oh that , yea you need a rear Tandem hub to get a 145 wide axle , Phil or Shimano hub..

    Good luck
    Bruce Gordon fits a MTB drive train and Bar end shifters, 9 speed on his touring bikes ..

    11/44 or 12/48 should be high enough..
