I wasn't sure if I was getting the alloy or plastic pulleys - but plastic arrived. I AM grateful to get these, nonetheless. Fit perfectly, easy installation, back in the saddle again! Installed on Simplex Prestige mounted on a 1970's Batavus. For $35 total, bike is back up and riding great! THANKS

The jockey wheels do work with the old simplex prestige derailleur. They are ever so slightly too wide which makes getting the securing bolt tension correctly somewhat difficult. The original simplex jockey pulleys are a totally different design than are the replacements. So far they seem to work.

For those who still use a vintage derailleur. This product works well with 70's French (Peugeot) bikes. Custom made to fit; so, save the metal parts. Noticeable difference in performance/shifting. All good. God send for my old bike.

While replacing the chain on my PX-10 with the original Suntour derailleur, I noticed the pulleys were literally falling apart. The conversion kit was an exact fit, and took only minutes to install. There's not instructions, but it's straightforward. Add lots of lubricant to the parts when installing.

I am happy to report that this pulley set was an exact match for my 1971 Raleigh Supercourse 10 speed with a simplex derailer. The overall thickness and screw (6mm) was a good fit. My bike is tuned up and so am I.
