Performance
|
SPIDER is a very light weight (1,265 grams/set)
metal rim clincher wheel for road racing and fast riding, sold factory built at a moderate $640/set price.
Its light rim weight lowers inertia and drives
excellent acceleration. Its design offers excellent stability and
handling. It comes in multiple spoke counts and configurations to maximize
performance specific to rider size and style.
2009 introduces our new version III rim. This is the first of a wave
of innovations that follow the fire that destroyed our composite production
building. The new Spider rim is stronger, stiffer and builds lower
spoke count, more aerodynamic wheels. It has stronger materials, more
precise tolerances, innovations in sectional design, and introduces our
new easier to mount and safer tire bead lock system.

Low Inertia, Excellent
Acceleration |
 Not only
light overall, its low mass machined sidewall alloy rim keeps the critical rim rotating
mass to a minimum (370g/335g) . The result is 101 gm2, a remarkable total
inertia for any wheel, especially at a moderate price. |
Lower Weight |
At
531g
total weight for a front 700C 16 spoke clincher, it easily rivals the most expensive competitors. |
Crosswind Stability |
The
proprietary shallow aero rim profile offers world-class side-on aero stability and side-on drag
performance. |
Better Handling |
Combine
the lively low weight and quick acceleration with Spider's laterally stable rim section
and the result is a delightfully firm and responsive
wheel. Matching specific spoke options with rider weights and styles
further enhances the ride feel. |
Confidence |
You
should be confident with your purchase. We offer a 30-day satisfaction guarantee, a
12-month limited warranty, and a no-fault reduced cost replacement program for the
original owner. |
Nine
Years of Proven Technology
|
Like every Nimble wheel, Spider's nine years and
three major generations shares 13 years of
technology investment made to develop and produce 18 generations of the Nimble
CROSSWIND. We design every
aspect of our wheels and their production. We manufacture and build our own tooling and equipment. We manufacture our
own proprietary composite with technology and materials comparable or
exceeding those used in the space-station and
state-of-the art fighter planes. Our design tools and test facilities are the best
available.

| 21mm Rim Drives the Design |
Spider's low profile 21 mm rim balances mass, strength, and
stiffness. The rim is extruded from proprietary aerospace quality aluminum
alloy. This alloy starts as US branded pure.
The rim weight is 370g/335g (700C/650C). The proprietary cross-sectional
profile optimizes side-on airflow. The machined side wall enhances braking.

rim images. |
| Rim Shape creates side-on Aero Properties |
The shallow aero sculpted parabolic rim shape fits within an
integrated aerodynamic flow design that offers excellent side-on aero drag. The high
fraction of open side area (86.5%) offers outstanding handling. |
Butted Stainless Steel Spokes |
 Spokes are
black double butted stainless
steel tapering from 2.0 to 1.7 mm.
Nipples are forged alloy. Wheel building tensions are 110+ Kg. Extra
narrow butted 2.0/1.5 spokes are also available as special order. Extra
narrow spokes trade
weight (~g/spoke) for loss in lateral stiffness with no effect on
durability. Extra narrow butting trades about 3% weight for about 10%
loss in lateral stiffness. Consult us to configure your order to an exact stiffness
requirement. |
| Precise
Light Hubs |
Our hubs are the same precise lightweight durable hubs used in FLY.
Our new front hub added
more than 24% to the lateral stiffness of the new Spider III front
wheels. The front hub weighs 65g, the rear
hub only 220g. Both designs use sealed cartridge
bearings. We are biased to the highest quality steel bearings rather
than ceramic bearings. Ceramic bearings are available as special
order. |
Multiple Spoke Configurations
Optimize Fit
 |
Spoke count options allow tensioned wheel designs to accommodate different riders
and race applications. Adding spokes trades an increase strength, stiffness and
durability for decreases in acceleration, and aero efficiency. To optimize rider
fit, Spider comes in 6 standard spoke configurations for each wheel size. We also
offer custom configurations to accommodate riders outside standard limits.

Hidden Spoke Nipple Aero Option |
Our new standard is to build with hidden internal aero nipples. Each configuration is
also available in standard access external nipples. Hidden nipples decrease spoke related drag more than 60%. This
option trades enhanced aero properties for reduced access to nipples for spoke
tensioning. Spoke nipples are tensioned using a 4.78 mm hex nut driver
(see Spider aero spoke tool) and are
accessed from under the tire. Also see spider
rim images. |
