What's the story with the seat post collar/lug/thingy?

...appears to be a custom fabrication, with a hex headed machine screw inserted from the other side to tighten the thing on the post. The head for the machine screw is a 3/16" hex socket, not metric. Which I presume dates the bike to back pretty far in the scheme of things.

I bought it from someone up in the foothills here who had not ridden it for a long while, along with a Carlton Flyer which he was riding on a trainer up there. The Flyer is beautiful as well, but needs some paint touch up and a few decals. Also both had wheel sets built up with 27" non hook bead rims, So I probably need to build some wheels for that one, which is spaced at 120 in the back.

What is the purpose of the small protrusion which appears to be at the bottom of the seat lug slot?

Look forward to seeing the Carlton Flyer thread when you are ready. :)

That shop was Diablo Bike in Walnut Creek.

I worked there in the early 80's. Different from Diablo Cycles.

...that's either a photographic relict or maybe some leftover blob of anti-seize that temporarily gooped out. :)

Some photos from today.

Here is the McReynolds bike that started this thread. Originally posted at Tom Fritts but Photobucket trashed the photos for 2005. Just trying to restore the thread. boone5: http://www.rockshow.rocktumblinghobb...8-9442a238.jpg

So I've been staring at this listing on Facebook forever and finally admitted that it's too tall for me. The bike has a 7in head tube and 33in standover - so a 58/59 I guess. Maybe it's a 60cm seat tube center to top? Anyway, it's a brilliant bike and appears immaculate. I really wish it fit me. Anyway, someone here should pick this up: https://www.facebook.com/marketplace...6216487002516/

Boone McReynolds designed and built the first "aero" bars well b4 Scott Bars
and one of his first riders to use them was Greg Lemond

alexihnen's purple McReynolds looks like a pure race bike, I see no eyelets and the stays look short considering the horizontal dropouts.

Reminds me that I picked up a McReynolds race bike in red, slightly big for me at perhaps 59cm(?), but it got buried behind a row of bikes out in the garage three years ago. I will have to gain access to it, since unfortunately I had a truck full of varied road bikes come in (right after I got the bike from a shop here that was going out of business).
There's a story about the row of bikes in the garage, about a retired, affluent older guy who fixed up and donated lots of bikes that were donated to him over some period of time. He put out hundreds of MTB's it seems, preferring those because they would hold up to real use in the hands of the poor and homeless folks that his church was assisting. So over time, the many road bikes he received mostly piled up in his basement. And though some he had already serviced, there were almost 25 of them just sitting. I can't recall how or why I ever was contacted by this fellow, maybe someone from a local shop gave him my name, but I ended up buying two truck loads of road bikes off him pretty cheaply. I had to work however to convince him to sell me the Ritchey P23 that he was about to donate to the homeless.

Anyway, the well-buried McReynolds has fairly steep angles I recall (I measured them, now thinking it was about at 74 degrees).
Thinking also that there is a Reynolds tubing sticker on it(?).
Thinking an hour or two of work might bring it out from behind that dense row of bikes.
Oh yeah, it's bright red!

Has mixed components but primarily Campy Record/Super Record as I recall. I'm now dying to get to it for a refresher course and to actually prep it and ride it for the first time!!!!!

Ironically I had just searched out this thread to gain more info on the Boone McReynolds history when this new bike popped up. Interesting to see the features Boone incorporated in bikes he built (even tho they were headed for different uses). Dupont Imron paint with matching frame pumps seemed to be one shared characteristic. That distinctive design of the seat tube clamp is another. In detailing my bike I found the serial number of 0011 on the bb. Anyone else have a serial number?

Vintage 80`s Boone Mcreynolds bicycle - $985 (dublin / pleasanton / livermore)

...kind of a mess, and way too expensive. But another one to look at.
