Wow. It never fails to amaze me how many people are so new to
bicycling and know nothing of its history. Campagnolo came out with
its 135mm bcd cranks in the mid 1980s. C Record I believe. Before
that all of the higher end Campagnolo cranks were 144mm bcd. 42 tooth
was the smallest chainring. I think this was the standard from about
the mid 1950s to the mid 1980s. Pretty much all of the European crank
makers copied Campagnolo and made its cranks to the same standard.
Zeus, Ofmega, etc. Can't think of any others at the moment.
Track cranks have more or less always been 144mm bcd. For the high end
ones. You can find a few makers using 130mm bcd but they are not
considered the top end track cranks.
As reported on this forum, Shimano used 130mm bcd from the early 1970s
on its Dura Ace brand, and maybe all of its sort of higher priced
lines. Don't know and don't really care what Shimano did or does.
