I just saw that I didn't updated the progress
I already made a new mould for the dropouts, a bit more "bulletproof" and with internal cable routing. First I just made a test prototype, and here are just a few more photos from those dropouts, just to show you how I will make it with the internal routing.
You can see the orange small tube - those small tubes will be in-laminated in the inside of the tubes and connected together in one smooth line, so that the cable will run smooth and the instalation of the cables won't be a problem. It's true that it will be a bit harder to make it, but it will be worth the extra work!
Rough dropout with cable:
The small tube in the dropout is slightly curved because the rear derailleur cable routing.
The weight of this dropout is at this moment 31.7g. Anyway, I will make a new pair of them and they still have to be a bit shorter for the frame etc.,..at the end it should be less than 60g for both dropouts.
I'm still very busy and hopefully I will manage to continue with the work soon, just can't wait that I make some more work on this project!
