Hi Louis Cypher,
your custom bike with integrated gearbox raised big interest on ridemonkey.com
G-BOXX topic as it is very similiar to Aaron Lahar's solution of Speedhub integrated DH gearbox bike. But your approach seems to be easier, more easily implemented. There are some things I would like to ask you regarding your design. Sorry for English but my German isn't what it used to be.
1) Did you use TS or QR version of Speedhub ? (from detailed fotos I'd guess QR ver.)
2) Did you shorten hub axle ? If yes, by how much ?
3) What is the overall width from outside-to-outside between mounting plates ? BB shell width? Inner Q-factor width ?
4) How thick are mounting plates ?
5) If you didn't shorten axle; did you make a thread to end of the axle (in order for the in-between nut to properly hold hub axle in mounting plate) ?
6) How did you mount an output sprocket to the hub shell ?
7) Did you used OEM Axle plate or OEM2 Axle plate ?
Thank you very much for your answer.
