Do yourself a favour and opt for either Suntour Superbe or Superbe Pro kit. The derailleurs are marvellous ... three different models (Front and rear) through the 80s/early 90s. The hubs run sealed bearings and roll close to forever. Brakes (the latest models had concealed springs) and early pedals were made by Dia Compe if I recall proper. Later pedals - again sealed bearings - had removable cages. Terrific stuff .... biased?? Moi??? SR took Suntour over in the 90s and, whatever you do, don't be fooled by SR Suntour Superbe labelled stuff. It's not.
