Whatta catch, that thing is bonkers! I've seen all those kinds of nice, vintage, craftsmanlike details and components before, but not all in the same place.

Nice score :thumb:

What he has on there now certainly isn't a 144 bcd crankset. Looks a lot like a Mighty Tour to me.

Yes Lascauxcaveman it was all those little details (and many I didn't know of until it arrived), the condition of that amazing racing seat and the complete condition of the bike that led my thoughts. This was a bike of intention, someone choosing to take the best, in some cases as with the Black version of the First Generation Dura Ace the rare and not afraid to mix parts from different nations, such as the Mavic as opposed to Araya tubular rims to build their one of bike. It is sad to think that this person died and someone dropped this bike off at Good Will, that won't happen again. I have a small wealth of grand children several showing interest in riding bikes, one who is getting her very first adult sized 700c bike built by Grandpa this Christmas. I have hopes in the next ten years that these bikes will get spoken for and then in good time passed on.

Here's what I found looking up the lead offered by cdmurphy that his is identical to a Centurion Professional, these are pictures for a 1988 Centurion Professional and the following are identical to the Sannow Sport:

Fast back chromed seat stay.

Yes, that photo is my bike, showing the OP what a Mighty Tour looks like. The OP doesn't have any great shots of his crankset on the new bike, but it does look like he has an early Mighty, with a 144mm BCD on there.

Polished chrome backs to the rear drop outs, the entire frame is chromed as is the Sannow Sport frame.

d'oh! Both those bikes look really, really nice.

And if you look at the first picture you can see the same lugs used though in this case not chromed and the icing on the cake the gold fill inside the lug cut outs. The forks are identical too with chrome tops and of Identical design.

cdmurphy you nailed it. :beer:

So thanks to you all I have answers to my frame tubing, when it was made, who made it and what bikes it was patterned after and are its identical twin siblings in frame/fork build.

Again, thanks, now it's up to me to make it right to ride and heal and ride. If they hold the Eroica in California next year that's my goal, make the 40 mile ride. :thumb:

I'll post when we pass each of these points.

Miki or Mikki was a contract builder in Sakai, Japan (suburb of Osaka). During the mid 70s to mid 80s, they were responsible for some of the better (best?) Japanese made bikes that were imported to the US. (Early Specialized Sequoia and Allez, Centurion Professional, Semi Pro, Pro Tour, some Super Elite's, Sekai 4000 and 5000, Some top end KHS bikes)

Thanks cdmurphy I will add this information to my bike file. Here's a better picture of the crank and it does measure out to be 144 BCD so I will be interested to see what the BCD of the First Generation Dura Ace cranks are, If I recall right Velo Base had them at 130 BCD. If they aren't then I will look for a Sugino Mighty Tour or consider my triplizer to get the lower gearing needed for old knees.

Here's a last little bit of detail these lovely Dura Ace brake cable clamps and from my builder friend the seat tube clamp design patterned after the French/Peugeot seat tube clamp? Thanks again, back to cleaning.

One last thought. I like wider tires and ride 28 & 32 cm tires on my 700c rims, would there be space? Wow, was there ever, no problem with fitting either tire on this frame, so nice when you reach a gravel or dirt section. :thumb:

Are those 23's or 25's? If 25's, 28's shouldn't be a problem. If 23's, might pay to test fit with a different set of wheels with tires of the desired size.

Shock and awe!

After 42 years when I inflated the tubular tires they held air, no not inflating them above 60 psi and not riding on them, but they held air! The side wall lettering is gone, only ink smears, but the calipers say either 22mm or 23mm maximum width which is about right for a 1976 racing bike.

After inflation, looking at the spacing I am certain I can fit a 28mm tire and quite likely a 32mm tire as height is not an issue for either the brake bridge or fork crown, only width, but there's still a lot of room to the sides as pictured above.
