I acquired the 84 miyata team from a neighbor

It has been a fun bike to do different versions of, which of course it a bit easier with friction shifting, if if does result in a mild franken bike

Latest changes were:
Swap out MA40 rims with GP4 rims (courtesy Mad Honk ) both to get to original spec and to run tubies (28 mm corsa control...to bad they don't make these any more they are nice)

Put on r8000 ultegra dual pivots.
I was fiddling with current brakes (super nice dura ace from rccardr also the crankset same source) and contemplating putting on some dual pivots from the recent @sloar sales and saw the R8000 on my parts self and thought whey not?

They brake so nice and match the black deore derailler (it was a parking lot change in the rain for Cino 2021 to match a 32 rear cog and 105 triple is was running for Cino... again different builds)

funny thing is with one more addition to my stash, a 7110 Durace crank I can get the bike back to original spec (in process thought i had one but some shipping confusion...we will see)

any way fun to have a base pallette so to speak for different builds, what are yours?

The idea of a "Frankenbike" is the result of lawsuits between component manufacturers, esp Shimano, starting in the mid 80s. Shim was trying to use monopoly business tactics with component group discounts and SRAM took em to court . Spoiler: Shimano lost in the early 90s (1991?). Spoiler: result is a ban on economically integrated drivetrains and a proliferation of "technically" integrated systems yay!!

Just don't worry about that. Bikes have historically been built with the combination of components that works best for a given situation. Just look at the mavic /simplex tdf bikes of eg lemond. They worked pretty well, or at least good enough for lemond

Sweet!

Very nice, I have a frame in 52cm which is sadly way too small for me, so if anyone is looking, drop me a line, I'm in western Canada.
