    2019 Crust Evasion, BBS02 or BBSHD, Shimano Alfine 8 IGH

    The currently available "fun" funds demand that this build proceed at a snails pace. It won't be cheap.

    Initial Specs: BBSHD 68mm motor with the Eclipse 42 chain ring on a 73mm bottom bracket, should end up with a 48mm chain line. I'd have used a BBS02 motor on this build but the Alfine IGH demands a tight chain line. If only Luna made a BBS02 Eclipse 2-piece chain ring ...

    UPDATE: The chain line for the Lekkie BBS02 40 tooth ring, mounted flat (no chain ring or motor spacers), on a 73mm BB measures 46mm, so that's the motor I'm using for now. For reference, the Lekkie 42 tooth ring doesn't come in as close - it's probably out at 55mm or so in the same situation.

    Otherwise, the specs and retro silver color components are pretty well defined:
    • steel frame tubes, fattish tire clearance with a narrowish Q
    • adjustable, replaceable 135mm rear dropouts with an inboard (within the frame triangle) disk caliper mount
    • 17AH downtube tray-mount removable battery
    • BBS02 mid drive
    • Lekkie 160mm crank arms
    • Lekkie 40 tooth chain ring
    • 1/8 inch chain
    • Shimano Alfine 8 IGH with a shift sensor - very nice shifting and just enough ratio
    • 1/8 inch chain
    • 24T Sturmey Archer rear sprocket, dish facing out
    • 26 by 2.35 Schwalbe Fat Franks tires
    • Velocity Blunt 35 disc rims
    • TRP Spyre cable brake calipers
    • Nitto flat bars
    I considered randonneur bars, but the resultant control issues aren't worth the cost.

    First for fun part test fitting:

    The build proceeds spoke by spoke, bolt by bolt ... I'd buy 'em built but few in the U.S. it seems want to sell complete, quality steel bikes with wide tire clearance and IGH drivetrains. No market I guess. Europe is a different case.
