I am one who likes the frilly lugs, the functional but not pretty Mafac brakes and levers, and the idea of French thread creating its own market for parts. I like the Lion logo and the overall color scheme. I like the look and the mystique, but I can not believe that the bike weighed less than a comparable Italian bike of the same period. OK, so the PX-10 is quoted as weighing 21.5 lbs, but I have and have seen lots of English and Italian and Japanese bikes of that era weigh the same. 21.5 pounds is a low average but it is still well in the spectrum of average. Perhaps the PX-10 frame was not even a light one after all, because the Delrin parts contributed to making the bike lighter too, so if the bike still only ended up weighing 21.5 lbs. than perhaps you could say that the PX-10 frame was a little heavier and the parts were a little lighter.
