• Out of curiosity (potential future buyer), what is the chainline requirement for the Katu (to know what measurement to target if changing the crankset)?

  • The models with internal-gear hubs come with:

    • 48T chainring
    • 18T sprocket
    • 1/8'' chain

    My model, Katu 30, has 5 speeds.
    The katu 20 has 8 speeds.

    The chainring I have now is 46T, and it's OK for Paris (I mostly hang around between the Seine and Clichy).

  • thanks for the info, but how did you choose the new bottom bracket when you swapped the crankset? is it a regular double crankset road chainline value?
    Regarding the change of shifter, was there any problem to set up the thumb shifter instead of the gripshift-like shifter? Nice car btw!
