My PX10e was purchased new, in March of '73. Since the serial numbers were assigned in hysterical order, I can't absolutely date it, but it appears to be a '72, or thereabouts. It has the 'plain' lugs, which are painted black.
The ride is anything but twitchy. It's quite laid back in the steering-quickness department... a very easy-going ride. I've always heard this from other owners of PX10's of this vintage, as well. I'm pretty sure the frame is a typical 72/72-degree affair, and the fork has a very large amount of rake, having a large forward 'swoop' in it. I've always heard that these frames had 72-degree head and seat tube angles.
A PX10 of the early 70's with a 76-degree head angle and twitchy handling doesn't seem to compute.
I'd be interested to hear what Dale and Jerry Moos think.

Apropos title for Halloween.
A good friend of mine brought over his PX-10 to examine.
He mentioned it was "twitchy" in steering and wanted my opinion. It is about my size, so I took it for a test ride, best description is
entertaining at the least.
An angle measure of the head tube read 76 degrees. fork rake I would guess was 40mm. With reference to the recent toe clip overlap thread, this one JUST missed interference.
What throws me about this bike is no trauma to the frame or fork, graphics that would place it to the early 70's, nervex lugs and the seat tube is 74 degrees. My guess is that the trail on this bike is quite small, an experienced
rider might find it amusing but I consider this one a bike that wants to go anywhere but straight.
I am aware that some of the later PX's had steeper head angles, but from my memory they felt a bit more neutral than this.
Anyone with similar experiences and or a modification that helped or (did not) would be appreciated. At this point he rode one of my bikes, an early Medici for all of 10 minuted and fell in love with it.
