cassette progression
 

Need some help figuring out what cassette my P8 Peugeot has. It is a 1983 build. The chainrings are 52 & 42. I can see that two of the cassette gears are 17 & 20. 17 is the second one in and 20 the third. I cannot find any other numbers. Any help from Peugeot pros would be appreciated.

um...I always count 'em. A 1983 would more than likely be a six-speed. A P8 probably has a 28 big cog and a 14 little cog...so, I'd guess 28-24-20-17-15-14, or something like that.

Thanks Luker,
Yes it is a 6 speed I should have mentioned that, There are two numbers stamped into the Sachs/Huret derailler of 14 and 28. The 14 may be the first one as the second is 17. I'll check it further this evening when I am home. I can always do as you suggest and just count them all, but I thought there might be some reference numbers to find.
