Treck cable OCLV guides

Chris M said:

I asked a while ago and I want to open up the possibilities to any
resource. I am putting together a repainted 1998 OCLV frame with a
threadless fork. Since 2000, there have been both prototypes and
production models of ultra-light versions of the frame, fork and I
assume any other parts not provided by sponsors like the cable guides
and the heaviest bit that seems absurd to hang on a SSLx or whatever
the model is with the 110[55 OCLV and boron in the BB shell. Is this a
case of making all the changes where you can claim them in the ads? I
find it hard to believe that Lance would have allowed it considering
the lengths he went to in the name of weight reduction (though I wonder
some times of some of the mods are for show, to psych out the others
that are carrying 2 STI levers in a group with Lance and he only has 1,
it makes a statement and maybe that is the most important mod to make
in racing bikes).

It's all kind of moot anyway since there is an imposed minimum weight
limit on the bikes anyway. I'm sure Lance could have made the limit
easily with two STI levers. OTOH, we may never know what other weight
they ADDED as a result - perhaps "special" stiffer frames for climbing
and descending? Steel steer tubes on the forks (not a bad idea
considering the speeds on the descent).

Are there any vendors that would create a front derailleur hanger in
aluminum? Steel is overkill especially since it can be easily replaced
as a throw-away after a wreck. You might even save money if the
derailleur hanger breaks off and saves the load from being focused on
the derailleur itself.

Aren't the already aluminum? I can't remember the last time I saw a
steel FD hanger. To get the "breakaway feature", you could just use
an aluminum bolt (though I suspect it could snap under the load caused
by a bad shift).

WRT the cable guides, those are much thinner and the weight does not
bother me all that much. I am thinking of drilling some holes and
placing some Nokon cable sleeves along the route and then I will jjust
hot glue them in and replace them whenever I change the cables.

Hot glue is SOOOO heavy though. Consider superglue. Use less, dries
into an aero shape.

Any ideas for improving the 1998 OEM parts here? Everything else is
ready to go and I would like to ride it as soon as the California
weather clears up for the season.

Replace everything but the frame. Components have lost a lot of
weight (on a cost/performance basis) over the last eight years.

I think some Lemond frames used a similar looking front derailleur
hanger in aluminum, but I'm not positive it would bolt onto a Trek.

A home-made carbon fiber front derailleur hanger?

I believe the other advantage was that he could trim the front derailer
more precisely with the (friction) downtube shifter.

I'm not a tremendous partisan, but the Campy Ergo shifters already have
ratchet-shifting on the front that allows simple and accurate trimming.

Trek OCLV frames are very light, but not among the lightest out there.
Most medium-sized (54-58 cm?) pro bikes seem to come in just a bit above
the 6.8 kg weight limit (some are 500g over, even), so it's reasonable
to guess that Lance's mountain specials were a matter of a stock frame,
complete Dura-Ace group (but with DT front shifting), and fairly
standard component choices for everything else, and probably came in
close to the weight limit.

Road bikes under the 6.8 kg limit usually engage in some sort of
madness: my own benchmark is that if your bike uses aluminum cogs or
carbon fibre chainrings, you're into the crazy end of components.

This may be less true now that sub-1000g frames are becoming almost
routine.
