No, the chroming is done after the frame is
built. That way the chrome even covers the brass.

As one clamps wheels into the frame, the paint will suffer damage from the skewer and from the axle locknuts. The chrome is a much stronger surface and will resist such damage.
However, the chrome is also slipperier, so there's a greater risk of the wheel slipping forward under chain tension.
Chroming on dropouts and front fork ends was common on high-quality bikes before 1974.
In '74, there was an "energy crisis" and the cost
of electricity rose drastically. Plating uses a
LOT of electrons, so most builders discontinued
this at that time. This was especially so in
England, where they were coping with a long and
bitter coal strike at the same time that the
price of oil was going through the roof as a
result of the OPEC embargo.

Somewhere along the line, diacritical marks, such as the "e" acute at the end of Ronald's town are getting stripped out of postings. Is it not possible to enable 8-bit characters and thus permit correct spelling of words not in English, without opening the floodgates of HTML?
It seems rather insular to me to reduce everything to 7-bit ascii on a list that deals with so many European topics and names.
