HI guys,

I just got a new bottom bracket for my Peugeot and I noticed there is a washer on the drive side of the axle. I can't imagine what the purpose of such washer is. Do you know?

According to SJS Cycles it is a limiter. I'm guessing it's to stop the chainset going too far on to the spindle and having a chainring rubbing on the chainstay. Somebody asked the same question on the SJS web page linked, "Plastic/Metal Ring On Axle".
