Mafac Straddle Cables and Rinko!

The old Mafac straddle cable was so short that it positioned the yoke directly in front of the tail-light. I decided to change both of them today but didn't have replacements....or at least I thought I didn't until a day ago; that's when I discovered that you can use old shifter cables. They have the same diameter and are flexible, just like the originals. In a couple of minutes I was able to reduce the size of the fixed-end anchors to fit the recesses in the Mafac spools. A little while later I had two new straddle cables and a very visible tail-light.

Rinko: When I built the frame I slotted the rear brake housing ends/guides but I forgot to slot the rear dérailleur cable housing stop and guide. I remedied that today. I haven't converted the fender to Rinko but I'll purchase a donor fender and rinko nut shortly to complete that step (VO 50mm Snakeskin if you're selling rinko splice pieces). I'll need to carry a lightweight headset wrench and removal of the rear yoke pulley is how I'd have to disconnect the rear brake cable to complete the disassembly; but iIt's got the essential rinko DNA. The cable guide/stop slots and a brass brush/copper slip ring assembly in the head tube/fork steerer; the fork can drop out without touching an electrical wire.

I love it when a plan comes together!

OK, guess I'm behind the times, as I had to look up Rinko.
So, pics or it didn't happen.

(what we can see looks nice)

How did you reduce the size of the anchors?

The anchor (or the side of the cable that you don't cut off) can be just the right size, or just a bit too big to fit into the thimble part for it to fit. I carefully "rub" these alongside the side of my spinning grinder wheel to reduce the diameter slightly.

Nice! I just got one of those slotted Nitto cable hangers that a seatpost bolt goes through on my Rinko - I realized the same thing as you. The Snakeskin fenders are pretty new, but I do have some Zepellin remnants that I think would work. Email me your address and I'll send you a slice.*

I'm thinking of building a new frame for myself, hopefully with your slip ring integrated in - I've studied your pix and your "white paper", but I may email you if I get stuck!

Compass has a "Mickey Mouse" rinko headset wrench which you probably know about. If you like to do your final headset adjustment with the stem in and tightened, it's no good. Here's a picture of a famous aluminum wrench maker:

Feel free to holler when you're ready to start with the slip ring; I'm happy to help. The second one has taken me a heck of a lot less time and futzing than the first so if that experience can be brought to bear on your efforts, so much the better.

Yes indeed, I'll build an aluminum headset wrench. I believe I have suitable stock kicking around in the shop.

Thanks for the offer of the fender splice piece; email to follow.
