TEST BUILDING THE MASERATI MT-7
Many
vintage road bicycles, as found, require little to make them road
worthy. The same was true for the Maserati, however, the term road
worthy would have to be stretched and stretched a great deal before the
bike could be ridden safely.
Once past the dented chain stay and flaking head lug
chrome plating, the next thing to warrant investigation was the
structural and geometric integrity of the frame set. In other
words, was the frame and/or fork set bent? If either situation
proved true, either repair would be needed, or the frame would be
tossed.
But
other things demanded attention also. The wheels installed were
twenty seven inchers, obviously wrong for the bicycle since the
Universal brakes were intended to accommodate 700c units. In fact, the
brake pads could not be adjusted to properly meet the braking surface on
the wheel rims. New wheels would have to be found, or perhaps,
shorter reach brake callipers. Fortunately, The Old Shed had
exactly what the doctor ordered - a very nice set of period correct,
Campy high flange hub set laced to Super Campion tubular rims.
Next on the already replaced list would be the
transmission. The rear derailleur, a very nice pre-Dura Ace Crane
GS, was obviously not original, having been installed to replace the
original
Campagnolo
Gran Sport model, or perhaps Nouvo Gran Sport would be more accurate.
Sadly, The Old Shed failed the Maserati offering up no GS derailleur.
With that in mind, the transmission would be built up in Nouvo Record
format.
One look at the freewheel and the reason for the rear
derailleur change out becomes obvious - the freewheel has a huge spread,
far too great for most Campagnolo derailleurs to accommodate.
Needless to say, the freewheel would have to go, along with the Shimano
Crane (early Dura-Ace) rear derailleur.
With those items changed out, the bicycle could be made
road worthy. With that plan in mind, and nothing more, the task of
measuring became the first exercise in building up the Maserati.
 When
checking for straight and true, start by looking. Look dead on
from each side to see how the forks look. Do they look bent
backwards, even a little bit? If so, there is work to be done but
the forks on the Maserati looked to be just fine - from the side.
Next,
consider the front of the bicycle, once again looking at it straight on.
Does anything look to be out of line? This will be a tough call
since all of the components will tend to interfere with one's line of
sight. But one sure check for bent is to consider the front
wheel's position in the forks.
Looking directly at the front of the bicycle, does the
front wheel appear to split the space between the fork blades evenly?
If so, there is likely nothing to worry about. If the wheel does
not sit dead center, then there might be issues that warrant further
investigation.
Next, drop the wheels and measure the distances between
the drops, both front and back. The rear measurement should be
either 120mm or 125mm, or extremely close to it. The front drop
space will measure either 95mm or 100mm, and once again the measurements
must be close to bang on.
Though the Maserati measured very close to bang on in the
frame alignment department, the drop space, at 118mm, was cause for
concern. The next step would be to install the drop-out tools,
used for checking to see if the drops were parallel to one another.
They weren't!
 The front drops were pretty close, which supported the
centered front wheel finding. Though close, they were not perfect,
showing a drop face to face measurement of 98mm and just slight
misalignment. None the less, a few minutes would be spent aligning
the front drops.
 The rear drop-outs were another story, to say the least.
Two to three millimetres too close together and miserably mis-aligned.
Was this how the bicycle was sold, or a product of improper packing?
The answer, needless to say, will never be known, but the results will
have to be addressed.
Some of the components on the Maserati were anything but
original issue. The gigantic freewheel cog set, the Crane GS rear
derailleur, the 27" wheels and the pedals would all have to go, each
being replaced with a period correct unit that would have been quite at
home on the bicycle back in the seventies.
With the frame issues recognized, understood and
repaired, all that was left was the assembling and tuning of the
bicycle. And that process, of course, would be followed by the
test ride - the moment of truth and one of the most rewarding
experiences in vintage bicycle ownership. Actually, the test ride
can also be one of the most miserable of experiences on a bicycle, if
one forgets to do this or that to something or other...
