I am not the greatest googler, I tried, I cant find it.

OK Then......When did disc brakes on bicycles become mainstream and popular?

"As it turned out, in 1975, Shimano actually had just released 2 versions of disc brakes for bicycles. -

they became popular (commercialy spreaded) in mid 90's along the downhill mountainbiking trend, but they should by far not be considered as mainstream in any case.
 
True, I dont know why I asked this question.

Oh wait, pondering it now. I guess I put an ad in the classified, guess I will change it now to mid 90's.

Which reminds me, I should go to the classifieds and repost everything so its at the top of the pile.

If you mean make new threads, then no, you should never do that, you should only bump your original threads by replying to them. Never create a new post for it, and never delete the old one and repost it.
 
The earliest bicycle disc brakes I'm aware of are the '70s Shimano brakes mentioned earlier, though I strongly doubt they were the first commercially available disc brakes for bicycles. You could buy them on bikes from Kmart, so there's no doubt they pretty much sucked. Despite being made by one of the big name manufacturers, they failed to catch on at that time.

The next widely sold bicycle discs were made by Sachs and Mountain Cycle in the late '80s. Sachs made small diameter rotor hydraulic discs that were similar to fancy moped items from the time. The most noteworthy thing about Sachs discs were that they brought the 44mm 6-bolt rotor mounting pattern that has become the predominant standard since then.

Mountain Cycle made cable-pulled hydraulic master/slave calipers and full-floating hard anodized aluminum rotors under the name "Pro-Stop". Those were seriously hyped as the Next Big Thing by publications like Mountain Bike Action. I have a set of Mountain Cycle Pro-Stop brakes with 9" rotors. They work fairly well, but they jingle a lot when rolling and they make a horrible honking racket in wet conditions.

Magura, Hope, Hayes, Formula, and Avid were part of the next wave of commercial development in the 1990s that left us more or less where we are now.
 
I have cable Avid BB5 160mm disc brakes, a quick scan of the interweb says the better option is the Avid BB7 in the 200mm range at a minimum for the front.

Does the mounting arrangement for the disc, change on the wheel hub, going from 160mm to 200mm? Most Likely Not!
Does the caliper change at all going from 160mm to 200mm? Yes - From 160mm to 185mm to 200mm

This seems like a reasonable price.

However I can get a pair of BB7 calipers for $70, the seller does not list whether its the newer bb7 or older, does not list whether its 160,180/185, or 200, also does not list whether its road or mountain. Lots of questions for an unknowledgable seller. Its exactly like looking at vehicles for sale on the dealer lot, with no years, no price, nothing. Forces you to make eye contact and communicate with salesman!
