One major area in which Campagnolo
outperforms that other company is wheels
(ShimaNO doesn't make rims or wheels). Campy has
for several years offered factory-built wheels based on a
high-profile, aero rim (the Shamal, Vento, and similar
wheels); for 1998, the line-up has expanded. In this
edition of Tech Talk, our expert, Tim Laflin, examines
the complete Campy wheelsets. (For our exclusive
discussion of Campy's '98 rim lineup, check here.)

Special Purpose Wheels
One of the areas that Shimano has been missing in
the market is the special purpose wheel. If you take a
look at what is available you will find that there a a
bunch of aftermarket companies making wheels for Shimano
equipment. Mavic, Hed, Rigida, Spinergy and others are
all focused on the Shimano market. Campy has the
components that Shimano is lacking in that they actually
make rims.
The special purpose wheel consists of 3 parts. The hub does not need to
be special, but Campy makes a number of special hubs
depending on how deep your pockets are. Shimano goes as
far as offering a slotted hub to make special purpose
wheels. The second part is the spokes.
Campy actually makes special spokes for their wheels;
Shimano leaves that to someone else. The third and very
important part is the rim.
Campy has the rim technology to deliver cutting edge rims
that Shimano lacks. With all three components in place
Campy can offer special purpose wheels that are exactly
Campy-compatible and reliable.
Any company competing with Campagnolo has their
work cut out. The Campy wheel is more than just a
straight pull spoke and an off-the-shelf rim. The rim
extrusion is similar to the standard production rims but
a little heavier to account for the increased tension of
the fewer number of spokes. The spokes are designed
specifically for the hub to allow fewer spokes and a
wider offset. You won't be pulling the radial spokes
through the hub flange, nor will the spoke heads snap off
as easy as a standard straight pull spoke.
This year Campy has addressed the Mavic Helium
issue with the Climb-Dynamic
wheels. As with last year, the Fluid-Dynamic
wheels are still in the line. Almost all special purpose
wheel sets are targeted to the racer. This almost goes
without saying for all the special purpose Campy wheels.
Riders usually have a set of heavy strong wheels for
training, and a set of lighter race wheels. In fact, as
you ride more miles a second set of wheels eases the
burden of having to repair wheels the same day. If you
are serious about training you can't take 3 or 4 days off
waiting for a wheel to be repaired. By the same token you
never go to a race with one set of wheels. I am always
amazed to see riders come to state wide events with a
single set of radial raced wheels and break a spoke in
warm-up and have to borrow a wheel. A back wheel
substitution can make shifting a real problem if you do
not get an identical swap. At the very least you will
need to adjust the brakes. So come race day or the club
rides you can toss on the good wheels and, if you have a
problem you have a spare. Don't spend all the time
training for an event just to loose with broken
equipment. If money is a problem get two conventional
wheel sets instead of a special purpose wheel set.
Climb-Dynamic
Wheels
This is a new wheel for Campy this year. It comes
in two flavors the Electron and Proton. The Electron is
high end version that uses the Record hub internals. The
Proton is based off of the Chorus hub internals. Both
wheels share the SWT rims with glass smooth braking
surface.
Campagnolo has revised the rear wheel on
Proton and Electron wheelsets! Check out our Rumors page
for more . . .
Electron
The Electron is the lightest version of the
Climb-Dynamic Wheels. It differs in only the hub to
the Proton. The one advantage the Electron offers is
a lighter 7000 series aluminum tubular rim that the
Proton does not. If you want to run tubulars this is
the only game in town from Campy on the Climb-Dynamic
Wheels. The Electron has a choice of clincher and
tubular. The clincher uses a slightly heavier 6000
series aluminum rim, but the majority of the extra
weight come from the clincher rim design. Clincher
always weigh more than tubular rims (for the same
strength) due to the design to hold the clincher tire
on the rim. The front and back wheels use special
high tension spokes and more aerodynamic hubs. The
Electron wheels use 24 spokes front and rear. The
fronts are radially laced and the back is radial on
the non-drive side and 1 cross on the drive side. (Campagnolo
has revised the rear wheel on Proton and Electron
wheelsets! Check out our Rumors page
for more . . .) The tubular front is a
light 681 grams and clincher is 733 grams. The rear
is 905 grams for the tubular and 965 grams for the
clincher. Compared to the Mavic Helium which is sort
of the bench mark, the Campy front is 30 grams
heavier and the back is 50 grams heavier. It is worth
mention that the majority of weight savings in the
Mavic wheel is in the hub which is not a big factor
in the performance of the wheel. The big item to note
here is the Campy wheels are significantly stiffer in
the few spins I have taken. If you are a heavier
rider, or a strong sprinter I think the Campy wheels
are a better choice.
Proton
Here is the big question: What am I giving up
to go with the Proton wheel vs. the Electron? The
answer is not much. If you are going to run clinchers
I can't see paying the money for the Electron. Just
taking the first catalog of the desk, Excel is
looking for $250 for the Electron front and $209 for
the Proton front. So $40 bucks is not much. The
problem comes in the back. The Electron back is $409
and the Proton is $299. For $160 more you can get a
set of Electrons. The weight savings is 50 grams in
the back for the Electron. The Proton rear is 1015
grams. The weight savings in the front is 12 grams.
The Proton front is 745 grams. All the weigh savings
of the Electron is in the hub which is the lowest
rotating mass in the equation. It is impossible to
tell which wheel you are riding from a feel
standpoint. The Electron does not pass the $1 per
gram test. It is, however at a hefty $2 per gram
upgrade.
It is a tough call. In the gram world we live
in I can't recommend the Electron clincher as a good
value, but at about $2.5 per gram from a major player
it is a sound value. My cutoff used to be $1 per gram
and it may go up this year. It will come down to your
wallet. As far as a tubular, the Electron makes the
upgrade value of 174 grams for $160 dollars a
definite green light. You will be hard pressed to
find a special purpose wheel that is better than
these. When a company has control of all the elements
in a wheel, the result is this good.
Fluid-Dynamic
Wheels
Campy has taken the Fluid-Dynamics to the edge and
back. I can comfortably say that Campy has the aero wheel
market covered. If you are shopping for a time trial
wheel, this is the place to look. These wheels differ
from the Climb-Dynamic wheels in that they are aero
section wheel that are heavier over all, but more
importantly heavier in the rim. The rim Climb rims are
box sections that plow through the wind. The
Fluid-Dynamics slice through the wind. The trade off is
Fluid-Dynamics accelerate slower and suffer in cross wind
drift compared to the Climb-Dynamics. It is a rare sight
to see any rider in the peloton using an aero wheel for
several reasons. It is not good to be on the outside spot
of the gruppo and have the wind push the bike into the
next rider. It is also not very useful to have heavy aero
wheels in a large pack that is shielding you from the
wind anyway. In order to cover breaks and react to
changes in pace an easy to accelerate wheel is a must.
Conversely, it is rare to see a rider in a profession
race not use an aerodynamic wheel in a single rider event
like a time trial, unless it is very hilly. Aero wheels
work, but make sure your purpose matches the wheel. An
aero wheel is great for a century ride to reduce effort.
In a 100-mile race where the pace out of corners is hard
and people is trying to break the pack, the aero wheel
will take its toll and wear you down. Choose wisely.
Ghibli
This is the disc wheel line for Campy. While
they are used in some road races, it is more common
to find them in use on the track. The wheel is a a
completely flat disc that is no wider than the rim.
It comes in a variety of flavors that you can see on
the official Campagnolo page. This wheel comes in
tubular form only and is more expensive than most
bike frames. The last ones I saw were in the $1,400
each price range. It is made in front and rear wheel
models. The front track style comes in 700c or
26" and the rear comes in a 700c with a 120mm
track spacing or in 700c with 130mm spacing and a 9
speed cassette body. I am not going to spend much
verbiage on these, since most people will never buy
them, but Campy does make a disc. I have never used a
Ghibli and am not familiar enough with discs to
compare them to other brands. If there is anybody who
can add comment on these wheels, webmaster@campyonly.com I will add it to the write up.
Bora
This is the pinnacle of Campy's road racing
aero wheels. The Bora and Shamal are very similar in
design. The Bora is the most aerodynamic of the open
wheels. The Bora has a 50mm deep aero (Shamal is only
41mm) section with aluminum brake surfaces embedded
on the sides. This construction is the most ideal for
an aero wheel. There are a few makers out there like
Corima offing a full carbon wheel. The full carbon
wheel is neat, but the braking surface degrades over
time and is positively dangerous in a little bit of
water. Aluminum is not great in the rain, but carbon
quite a bit worse even with special brake pads. The
older Bora wheel used to be all Carbon. If you look
at Jan Ullrich's wheels in 97 tour you will see he is
still riding the old Bora. The older version was
nearly 250 grams lighter than this years Bora. The
new construction of the Bora makes for a better,
safer and heavier long term wheel. The rim section is
19mm wide to allow a narrow tire to still hide the
rim. The Bora features are the HPW hub which hides
all the spoke heads and the rim covers all the
nipples. The deeper aero section is you are paying
for. The internal hub pieces are from the Record hub
so you get the Ti axles and sealed bearings. These
wheels are so expensive that I have never actually
built a bike with them. The 12 spoke front wheel is
830 grams and the 12 spoke rear is 1040 grams in a
tubular rim which is all that is offered. Hey, if you
have the money for these wheels, tubular tires are
not expensive. I can't find a mail order price on
them, but a rough guess would be around $1050. This
wheel is just too expensive to justify the cost. It
is no lighter than the Shamal, but costs around $200
more. You will need to be a very serious competitor
to spend the extra money to get 9mm more aero depth
for $200.
Shamal
This is the Campy's aero wheel that most fat
wallet people buy. The new version is going for about
$850 from Excel. This is wheel comes in both tubular
and clincher. The price tag is hefty and orders have
been slow. It is sort of a cost reduced Bora. The
Shamal falls back to the 96 version with respect to
16 spokes in the rear. The Bora maintains 12 spokes
front and rear, while the Shamal goes back to 16 for
98. The aero section rim is all aluminum and it is
41mm deep compared to the 50mm for the Bora, but is
still 19mm wide like the Bora. The Shamal still uses
a Record grade (HPW) hub. The Shamal 12 spoke front
wheel is 800 grams in tubular and 825 grams in
clincher. The Shamal 16 spoke rear wheel is 1050
grams in tubular and 1080 grams in clincher. The
Shamal is on par weight wise with the Bora, but the
Bora; with its deeper aero profile, wins the
performance race. When the Shamal started out life it
was about $150 less than today's version. The $850 is
probably going to keep most people away.
Vento
This wheel is the first wheel that most
serious riders will buy. You can get a set for about
$625 from Excel. I am sorry to say it, but the Bora
and Shamal have just gotten a little out of control
in the price arena. Vento is not the best pick in the
top performance for the buck from Campy. The Vento
uses the same rim as the Shamal, but it has 4 more
spokes up front. The Vento 16 spoke front wheel
weight is 914 grams in clincher. The Vento 16 spoke
rear is 1133 grams in clincher. The Vento is offered
in 26 inch wheels also, with lower weights. You can
check it out on the Campagnolo page. The front wheel
picks up 99 grams from the Shamal and the rear is 83
grams heavier. The front weight is more a function of
the extra spokes than the hubs. The rear weight is
mostly the hub. The Vento gets a Chorus grade HPW hub
that makes it heavier due to the steel axle and
hardware, compared to the Shamal and Bora with Record
Ti parts. The bottom line here is for some weight in
the hub and a few more spokes, you get a wheel that
almost matches the Shamal. The $225 extra bucks to
get to the Shamal is a little above the gram per
dollar mark. You save 182 grams. It is a decent
upgrade and misses the $1 per gram good value mark.
If you have the money or want to run tubulars move up
to Shamals. Tubular Shamals pass the money and grams
test over the Vento, but not as clearly over the
Zonda. This year's improvements in the Zonda make it
much more attractive than the Vento on a price and
performance basis.
Zonda
Take one more step down and the Zonda is your
wheel. For about $150 less than the Vento the Zonda
offers a lot of performance. The hub is the same as
the Vento and it has all the same features with
respect to the hubs and spokes. The rim is slightly
less aero with a 38mm deep aero section, but it is
still 19mm wide. The 16 spoke front clincher is 857
grams and the 16 spoke rear is 1104 grams. While you
are dropping 3mm in aero profile the Zonda is lighter
than the Vento. It would most likely be a mistake in
my opinion to move up to the Vento over the Zonda.
The Zonda has nearly all the aero features like
concealed nipples and spoke heads, and it comes on a
Chorus hub like the Vento. I feel like the question
here is Zonda or Shamal. The step to Shamal may be
too big for most riders. You are looking at an almost
2 times price jump to move up to something better. My
advice is to stop at Zonda and forget Shamal and
Vento. If the Shamal was in the $500 to $600 range it
might be a jump to make.
Scirocco
This wheel is fairly far down the food chain
in the Campy line. This year it gets a strength
improvement with the higher line straight pull spokes
and reinforced drive side hub flange. The stronger
rear drive side makes this a better wheel than you
can build with stock components. The rest of the
wheel design is fairly standard. The spokes have
exposed nipples and the front hub is a standard hub
flange, just like the non-drive side of the rear. The
rim width is 19mm and the aero section is 34mm deep.
The front and rear wheels each use 20 spokes. This is
the last of the Campy wheels that I would consider to
be advantageous to buy over a stock hub and rim
combination. The only spokes on this wheel that are
bladed are the drive side high tension spokes. The
rest of the spokes are aero, but not to the degree of
the more expensive wheels above, and are a standard
looking bent head spokes. If you are still using 8
speeds this is the best wheel in the line that is
still available in 8 and 9 speeds. The front clincher
is 887 grams and the rear clincher is 1113 grams for
9 speeds and 1193 for 8 speeds. The hubs in this
wheel set are of the Veloce/Athena hub design. The
hubs are still easy to service and good for many
miles. Excel is offering this wheel at about $410.
Eurus
This is the last aero wheel in the Campy line.
Eurus is designed for the Mirage and Avanti
equipment. It uses the sealed bearing hubs from these
lower lines and comes in 8 speeds only, to match the
Mirage and Avanti gruppos. There is noting really
remarkable about this wheel set other than it is a
good set of wheels for a low end bike. It uses a
standard hub flange and standard spokes and an aero
rim with 19mm of width and 30mm deep in the aero
section. The non-drive side is radially laced, but
the front uses a 1 cross pattern. The front wheels is
878 grams and the rear is 1151 grams with clincher
rims. The Eurus will most likely run in the $320 area
from a mail order company, for a set.
When writing this I happen to have the Excel
catalog #36 sitting on my desk and a wholesale price
list. The prices are all from Excel just for reference
and will most likely change. For the wheels that Excel
did not list I gave a rough stab at them knowing the
wholesale price and the margin that Excel charged on the
other wheels. Just in case you are wondering, I do not
wish to give out wholesale prices and I guarantee Excel
is not getting rich on a single order of wheels. Shop
around and try to get a set of last years wheels or get a
used set off the Campy Only page.
I would avoid the 12 spoke Shamals from 97 simply
due to the fact that Campy is not making them in 98. The
16 spoke versions from 96 and 98 are a much sturdier rear
wheel. If you get a set of 12 spoke wheels, get some
spokes also. It would be a good idea to have an extra set
of spokes for all the special purpose wheels, because the
local shop can fix them, but they will not have the
spokes in stock. One final note is that if you get a
Zonda or above wheel there is a special tool is needed to
true the wheels. It reaches down into the rim to tighten
a 5.5mm nut/nipple. If you do not have access to this
tool a Snap-On brand 5.5mm deep reach socket will do the
job. Snap-On is the only socket I have found that will
fit the rim hole and the nut, since the socket wall is
thin enough.
We Road Test the Proton Wheelset
Your webmaster has been using a set of
Proton wheels for about a year now, mostly in a number of
hilly, ultramarathon events. Here are my impressions and
experiences:
- The wheels are very attractive and
still very unusual in most pacelines. The HPW
hubs are striking and unlike anything else on the
road. Overall, I like the look of the wheels much
more than any competing wheelset (like Mavic's
"Helium" wheels). The Proton wheelset
also doesn't come in a funky red color (like
Heliums) that looks funny with most frames.
- I like the "ride" of the
wheels. The HPW hubs allow the spokes (24 on the
Protons) to carry up to three times the tension
of a traditionally spoked wheel. Campy's official
specs call for up to 160 kilograms of tension in
the rear wheel drive-side spokes. What this means
on the road is that the wheels feel very quick
and fast. The ride is a little more harsh than a
standard wheel, but comfortable enough for my
long distance events.
- How durable are
they? I've had mixed
luck with my Protons--sorry to say, quite a dose
of bad in with the good. I put about 500 miles on
my first set of Protons, and they remained very
true and straight--until a spoke let go on the
rear wheel. I was 180 miles into a double
century, slowly pedaling away from a rest stop,
when one of the drive-side spokes on the rear
wheel broke off at the hub. Because of the
tension in the spokes, and because there are only
24 of them, losing one spoke throws the wheel way
out of true, and I was forced to limp back to the
rest stop, where they were able to true the wheel
enough for me to finish the event. After the
event, I sent the wheel back to Campagnolo USA,
which fixed it for free and shipped it back to me
within a week. The new wheel lasted for a few
months, until a spoke let go in it, too. I
shipped that one back to Campagnolo, and they
replaced it with a newer version of the Proton
rear, which now has a different spoke pattern and
beefier spokes (Check out our Rumors page for more). That one had about 200 miles
on it when it, too, lost a spoke--the first such
spoke breakage that the folks at Campagnolo USA
have seen in the revised Protons. I'm now on my
third rear wheel and waiting to see how it holds
up.
- August 1999: The double century
season is over, and the rear wheel shipped to me in February is
still holding up very nicely after several hundred training miles,
four DC's, and the steep and sometimes rough Climb to
Kaiser. Campagnolo's latest effort, it seems, can be
trusted. So, would
I now recommend these wheels? If you're looking for a
very light, attractive, and lively wheelset, my answer is a
definite "Yes."
- Next Up--We'll be contacting Campagnolo to
start a road test of the new Neutron wheelset. Watch this
site for results!
