If anyone is able to view some issues of "Cycling"
from the early to mid '70's you'll see some
interesting component trimming there, too. The most
extreme was a bike ridden by either Alf Engers or
Derek Cottington that had it's Campagnolo hub and
pedal barrels slotted--the hub axle was painted in
world champions' stripes that were clearly visible
through the slot! This in addition to the usual
half-taped bars, hoodless brake levers, Campionissimo
Seta Extra tires on 24 spoke wheels. I don't remember
seeing weight specs on any of these bikes, it's just
how most of them were pictured with a few closeup
shots of interesting details. I haven't ever traveled
to or lived in Britain, it's just that in Los Angeles
ca. 1970 it was easier to find "Cycling" than
