• Back to the back brake routing question, this looks like quite a simple/elegant solution to route past a BSA BB

  • A very good point....
    I'm convinced that downtube external routing is too ugly so that will have to go inside, but I'm fairly relaxed about external chainstay routing...
    As far as I can see, the options are:

    • Thru DT - thru T47 BB - thru CS
    • Out of the DT - under the BB - back into CS
    • Out of the DT - under the BB - outside the CS
      Given your good point on the weatherproofing of the DT - CS concept above I think I'm inclined toward internal DT/external CS.
