If the difficulty of polishing the "nubbed" flutes is your biggest rap on Nervar, his is the answer:

This is a Nervar Sport triple, with Nervar, not TA, rings. The later, probably 70's, arms have smooth flutes with "NERVAR" in raised letters. I also have two 3-arm 116 BCD Nervar cranks with the same style arms.
The inner ring TA chainring bolts (middle set of bolts) are the ones I sought in a previous post. They have slotted heads like the large-ring-to-crankarm bolts, only slightly larger. They are slightly longer than the newer allen head bolts which were made for rings with countersunk holes.

\r?\n> As the owner of about 4x Nervar
\r?\n> cranksets, I have to disagree slightly

\r?\n> (Raleigh Supercourse
\r?\n> MK2 models, 3-pin with alloy rings), and 2 Nervar Star
\r?\n> (5-pin, 128
\r?\n> bcd) models.

\r?\n> There is one huge downside to ALL nervar alloy cranks, and

\r?\n> Bicycle Team.

\r?\n> The alloy cranks have nubbed arms, and they are fully 100%
\r?\n> polished
\r?\n> cranks. I don't know if you ever tried to polish
\r?\n> nubbed arms, but
\r?\n> it's exceedingly difficult to polish in the vallies between
\r?\n> the nubs.
\r?\n> At least with Campagnolo Nuovo Record derailleurs (the only
\r?\n> other
\r?\n> nubbed alloy parts that I'm aware of), the derailleurs are
\r?\n> anodized,
\r?\n> and the nubs are aligned in rows and columns, so they clean
\r?\n> easily and
\r?\n> won't tarnish.

\r?\n> In the original TI Raleigh Team article, they complained
\r?\n> about the
\r?\n> first-year 1973 parts (Nervar Star cranks and Huret
\r?\n> Jubilee
\r?\n> derailleurs), saying that once the Nervar Star crankarm
\r?\n> turns grey, IT
\r?\n> STAYS GREY, FOREVER, and also they complained that grit
\r?\n> will easily
\r?\n> jam inside Huret Jubilee derailleurs and foul the
\r?\n> shifting. These
\r?\n> problems were especially acute in the wet environment of
\r?\n> the U.K.
