Vivo rear mech no19 recieved as a pre production sample at eurobike in late 90s, fitted for testing then removed and left in a box of bits. so whats you think this hens tooth in unicorns shit is worth???
 
Straight cable pull but despite the cover nothing more. I like more the SGS system: you control rear and front derailleurs with only one shifter, the syncroshift
