result? the vigorelli is a complete noodle & a shimmy nightmare.
now, some of the shimmy could be the wheelset. i experimented with a
badly shimmying frame a while back & was able to tune out some of the
resonance with a stiffer rear wheel [straight gauge spokes drive side
& hub with a fractionally better bracing angle] - improved the ride
substantially, but the frame still had the propensity to shimmy. same
with the vigorelli, even with a straight gauge spoked rear....


How about wrapping the tubes in the head tube/down tube/top tube are
with carbon fiber composite to add some stiffness to the frame?

like carbon cranks? sure, that would work. better off not bothering
with the steel in the first place if investing that kind of effort though.

honestly, i'd love to be a die-hard steel guy, but aluminum frames seem
to be so much superior in this important regard, i do all my serious
mileage on them these days. curved seat stays & carbon seat posts make
the ride just as comfortable as steel.
