Peugeot was good at making their high end and entry level road bikes look similar to the casual observer.

Look closely at the promotional picture of the Pro 10 and compare it to your bike.

Especially the stays and forks.

I suspect yours has stamped rear dropouts and is probably lower end tubing. Depending on the year, I think it is either marked as Carbolite or HLE. Still a fine riding bike, but not an X10 level bike...

An X10 level bike would have forged dropouts, high grade tubing and be significantly lighter than yours is likely to be.

I could be wrong, as I have never owned a Peugeot, but just seeing the pictures doesn't make me think your bike is the same type as the one in the promo.
