winter project this year has been to build up a road bike with a
Premium 8-speed Shimano Nexus hub. Having discovered a 1988ish Norco
Monterey which features a nice cromoly, double butted Tange frame,
I ordered a new Nexus premium 8-speed hub. Whilst awaiting its arrival,
I stripped the Norco down, overhauled the b/b and headset and then
rebuilt it up replacing the “heavy metal” components with some light
weight stuff I had lying around, weighing the difference between
the original and replacement.
replacement 1980 Campy Record brakes and crank, aluminum bars and
seat post for steel, a single-speed rear wheel with CXP21 rims for
the original 6-speed and a matching CXP21 front wheel gave total
savings of no less than 4lb! With the quoted weight of the 8 speed
Nexus unit being about 3 pounds, the final configuration is 2lb
lighter than the original Monterey.
as per Grant Peterson, I fitted Nitto Moustache bars to improve
the braking effectiveness of the old Campy sidepulls. Butchering
an old T/T Profile bar I made up a bar-end attachment to make the
road bars compatible with the 7/8’’ Revoshifter. The 3/4” silver
inner portion is secured to the inside of the moustache bar by the
taper nut and the black outer section screwed to it by two self-tappers.
It works perfectly and was so simple to make that -as shown in the
picture, I made up a second unit! The most time consuming part of
the conversion was the setting up of the bar/brake-lever relationship.
may get a matching Mavic Open Sport front wheel to match the rear
but am too busy riding at the moment! I’m amazed at how well it
has turned out and can understand the much-lamented Sheldon Brown’s
enthusiasm for the hub. The 42/19 sprockets give 8 reasonably spaced
ratios between 30 and 100 gear inches, the shifting is excellent
and certainly at speeds less than 30kph, there is no noticeable
loss in transmission efficiency.
