Another Mixte

New front derailleur is at the back. The other one had been rubbing on the chain for a long time and is almost warn through. Both are ....

Donor bike

This bike (Repco 83/ 84 mixte) was listed for sale on Facebook marketplace for $20.00, and was about 1km away from where I live. So I was able to ride to pick it up, and wheel it home, riding one bike and wheeling the other. 

I was quite pleased to find it had interesting Suntour gears on it, and despite some plastic bits broken, I was able to fix them. It now rides quite well. I didn't touch the brakes: all the fixing was in the drivetrain, and I regreased the bottom bracket and used the donor bike chain. Very pleased with how it turned out and I like the sombre dark purple colour.
