Buying A New Road Bike
It's A Great Time To Shop
 The road bike: the world's most efficient
machine.
You couldn't pick a better
time to shop for a new road bike. Today, manufacturers offer more models than
ever in a wider variety of price points. And component companies make an
exceptional array of top-notch wheels, brakes and shifting systems that operate
like never before. For example, it's possible to get 27-speed drivetrains that
shift blink quick, and wheelsets so light pedaling is effortless. In fact, there
are so many attractive choices today, that if you just walked into our store,
you might be overwhelmed.
Don't be. Having a lot of choices is a
wonderful thing because it drastically increases the likelihood you'll find the
perfect bike -- as long as you know a little about what's available.
To
help, we've put together this comprehensive guide for finding the ideal road
rig. We explain the decisions you need to make and offer advice on everything
from frame materials and wheels to gearing and component choice. To start,
though, you need to do some self analysis (therapist not
required).
Answer These Questions Before visiting our showroom,
define yourself a bit. Consider how you'll use the new bike once you get it, as
well as where you'll pedal once you've had the machine for a while. And ask
yourself a few questions to figure out what model's right. Are you:
A new cyclist?
Into improving fitness (medium to long rides)?
Interested in touring?
Training for an event?
Getting into road racing or triathlon?
Thinking of commuting to work/around town?
Analyze
Yourself Also, consider how many miles you might log per week, or year.
And think about your tendencies in purchasing other things. For example, do you
consistently demand the highest quality, or are you more apt to look for
reasonable quality and lower cost? Do you dig trick, high-tech gadgets or are
you satisfied with simpler designs? Additionally, it helps to know about how
much you want to spend because that's a quick way to focus the selection process
on the appropriate models.
Answering these questions will ensure that
you get the best bicycle. We'll be able to show you models with the right
features for your needs, interests and budget. And you'll soon be sailing down
the pavement with a big grin on your face.
Variables Of Today's Road-Bike Market
There are lots of
fascinating variables in choosing a modern road bike. The rest of this article
explains these choices so you'll have an easier time selecting your dream
machine.
Frame And Fork Materials
 Fine frames are built from a myriad of
materials.
Although over the years
there have been such oddities as bamboo and plastic frames, current road bikes
are made of one or blends of these four materials: steel, aluminum, titanium and
carbon fiber. We get into the differences below.
But first, realize that
fine bicycles are built of all these materials. Also, two frames can be
constructed of the same material yet have entirely different ride qualities due
to differences in geometry, assembly, tube shape, and material manipulation
(reinforcing a tube, for example). Which is one of the reasons it's so important
to test ride and feel the bikes you're thinking of buying.
A tip for
inspecting frames: Look for a tubing decal on the seattube or downtube.
Sometimes manufacturers provide these and they usually explain what brand and
type of material is used in the frame. We're happy to elaborate if you have
questions. Just ask.
Steel The most traditional frame material,
steel has been used by framebuilders for over a century. Many types of steel
tubing are available and the material is easy to bend and shape. Plus, there are
myriad methods of assembly making steel very adaptable to cyclists' needs. It
also offers excellent ride quality, durability, is easily repaired and
affordable. If there's a knock on steel, it's that it tends to be heavy when
low-quality tubing is used (found on bikes sold at department stores). And steel
can rust if treated carelessly (protect that paintjob!).
Entry-level
steel-frame bikes are usually less sophisticated than those typically favored by
discerning cyclists and steel fanatics. But, the affordability of the lesser
steel frames usually allows you to get a better level of components. And, it's
possible to make a fine-riding steel frame on a budget by cutting back on some
of the frills that add cost. For example, such a frame might feature less-costly
TIG welding compared to the fancier lug construction on the higher-end
model.
High-quality steel frames integrate great design, superior
assembly, and better alloys in the tubing. A popular quality steel for bicycle
frames is American SAE 4130 steel, better known as "chrome molybdenum," and
referred to as "chromoly" or "chrome-moly." And, there are plenty of other
impressive alloys offered by tubing suppliers such as Columbus, Reynolds, Tange
and True Temper. Frames built of these materials are famous for their
combination of responsiveness and comfort.
Steel is an excellent fork
material. It can be formed into any shape; even aero ones. It's plenty strong.
And, it also absorbs shock to soften rough roads. Steel forks are heavier than
those built of lighter materials such as aluminum and carbon
fiber.
Aluminum Aluminum was first used in frame construction
in 1895. But, it didn't come into wide use until the 1980s when large-diameter
tubing was conceived and construction processes were perfected. Now, it's the
most popular of frame materials. It's subject to the same variances in assembly
and quality as steel. And, like steel, as you spend more, you get higher quality
tubing and better construction.
The buzz about aluminum is that is has a
more jarring ride than the other materials. But, while this used to be the case
in its early years, it's not a problem today thanks to new aluminum alloys,
tubing enhancements and improved construction techniques. These allow the frames
to absorb shock better than ever while still offering the wonderfully lively
ride that makes aluminum all the rage today.
This magic ride is
attributed to aluminum being the lightest frame material -- even lighter than
carbon and titanium. It makes aluminum frames great choices for racing and time
trialing. And, unlike steel, aluminum won't rust; another
advantage.
There are various types of aluminum tubing in use by
manufacturers. Some common types are 6061 and 7005, numbers that refer to the
alloys in the aluminum such as magnesium, silicon and zinc (pure aluminum isn't
strong enough for bike use). And, there are some new superlight tubesets such as
Easton Scandium. Be sure to ask if you have questions about an aluminum bike in
our store and we can explain further.
Aluminum forks are generally stiff
and light, and can be shaped aerodynamically. They also offer excellent
compliance for comfort on rough roads.
Titanium Titanium (also
called "ti") is one of the longest lasting, strongest, and most expensive frame
materials. Many cyclists and experts feel that it combines the best
characteristics of all the other frame materials. It rivals aluminum in weight,
is as comfortable as steel and it has a sprightly ride and electric handling
that many riders swear by. The frames feel "alive," as if each pedal stroke gets
a boost from an inherent springiness in the frame.
Titanium is hard on
metalworking tools, requires expensive titanium welding rod and must be joined
carefully in a controlled environment. Consequently, titanium frames are very
expensive to produce, which explains their high purchase price.
The two
common types of titanium are 3Al/2.5V and 6Al/4V. These designations refer to
the amount of aluminum (Al) and vanadium (V) alloys used in the titanium. 6Al/4V
is more expensive, lighter, harder to machine and stronger. But both titanium
alloys are excellent; they may even be combined in a frame.
Only a few
companies manufacture titanium forks and they are very expensive due to the
additional costs in material and construction. Also, because extra strength is
needed in the fork steerer (the upper tube), ti forks usually outweigh other
high-tech tillers. These two considerations are why most ti frames come with
carbon forks.
Carbon Fiber Carbon fiber (also called "carbon"
and "graphite") is a relatively new material and unique because it's not a
metal. It's a fabric that's impregnated with a glue called resin that allows
shaping and joining the material. Carbon frames are extremely light, stiff and
durable. Its greatest advantage is that carbon can be manipulated essentially in
endless ways (because builders can orient the fabric strands however they want),
which means it can be fine-tuned to provide just about any ride qualities
desired. It's also impervious to corrosion and can be built into beautiful
shapes producing Ferrari-like looks.
Like titanium, because construction
is somewhat complicated and because carbon fabric and resins are costly, carbon
frames are on the high end of the cost spectrum. To describe these frames
manufacturers use terms such as "high modulus" and "void free," which tells you
that it's high-quality carbon fiber material and stellar construction.
Sometimes, these designations appear on frame "tubing" decals. Be sure to ask if
you have questions about the carbon material used in a frame.
Carbon is a
popular material for forks due to its natural ability to absorb shock while
offering fine handling. Although, they're not the best choice for heavy or
aggressive riders, there are even all-carbon forks (weighing less than a pound).
These are great if you want a superlight road bike. (Other carbon forks use
steel or aluminum for the steerer.)
Choosing Gearing
 Selecting the correct gearing means easy
pedaling and happy knees.
Regardless of what bike you
choose it won't be much fun riding it if the gearing isn't appropriate for your
fitness level and where and how you pedal. Fortunately, all component groups
offer a variety of different gearing options. And we can also modify things if
needed to suit your needs. Here's what's involved:
Chainrings and
Cogs There are sprockets on the front and back of the bike. The fronts
are called "chainrings" and they're located on the crankset, the part that the
pedals are attached to. The crankset comes with 2 (called a "double") or 3
chainrings (called a "triple"). Triple cranksets include a small inner chainring
(sometimes called a "granny") that offers easier hill-climbing gears.
The
sprockets on the rear of the bike are called "cogs," or, if you're referring to
the entire cluster of gears, it's called a "cassette" or "freewheel." The
cassette is attached to the rear wheel to drive it as you pedal. Depending on
the components on the bike, there will be from 8 to 10 cogs on the rear
cassette.
How Many Gears? To figure out how many total gears
are on a bike, simply multiply the number of chainrings by the number of
cassette cogs. For example on a model with a triple crankset and a 10-cog
cassette, you have 30 gears -- quite an upgrade from the 10-speeds so popular
years ago.
How many gears to get depends on how and where you ride. If
you're reasonably fit and bike in flat to rolling terrain, you'll probably be
fine with a double chainring and 8 to 10 rear cogs. If it's hilly and you're
getting into shape, consider a triple chainring and its easier
gears.
When considering how many rear cogs to get, keep in mind that
you'll have plenty of gears even if you get an 8-cog cassette. If you go to more
cogs, you can either get a wider range of gears or more-closely spaced gears.
The latter is excellent for racing and training because it makes it easier to
fine-tune pedaling effort. Wider gearing offers easier low gears so it's ideal
for mountainous riding and for when you're not in tip-top shape.
How
the Gears Feel To figure out how easy it is to pedal the gears, you have
to know a little more about the chainrings and cogs. They are referred to by the
number of teeth on them. So, you might read in bike specifications about 39/53
chainrings and 12-23 cassettes. This means that the small chainring has 39 teeth
and the large has 53 teeth and that the cassette has a small cog with 12 teeth
on it and a large one with 23. To know the size of every cog, you usually have
to count each one (usually cogs and chainrings are marked, but, the marks can be
hard to see).
Know Your Numbers Don't let the numbers confuse
you. The key thing to know is that for chainrings, larger numbers mean it's
harder to pedal and vice versa. For cogs, it's the opposite: the larger the
number, the easier it is to pedal and vice versa. By keeping these rules in
mind, you can quickly see that a 30/42/52 triple crankset and a 12-30 cassette
will offer much easier gearing than a 39/53 double with a 12-23
cassette.
Pondering a Triple Many people wonder whether or not
they need a triple crankset. Our advice is that it depends a lot on how and
where you ride. If you like the hills, ride fairly long distances, sometimes
carry gear and aren't training all the time to be in optimum fitness, a triple
is a great thing to have. Even if you don't use the small chainring all that
much, it can be a lifesaver at the end of a long ride when a tough climb stands
between you and home.
Even some competitive riders favor triples, though
if you're really strong, you may decide to forgo the additional grams of a third
ring. Also, a triple-chainring drivetrain shifts slightly more slowly than a
double, which is a consideration in a race when a slow shift can cost you a
podium spot.
If you're not sure which is right for you, we recommend
coming in and trying a triple to feel how it works for you.
Cassette
Considerations You also need to decide on the range of gears on your rear
cassette. Here's a guide to some commonly available sizes and what they're
designed for:
| cassette |
what it's good
for |
| 11-21 |
stronger/competitive riders on flat
courses |
| 12-23 |
stronger/competitive riders on varied
terrain |
| 12-25 |
a combination that begins to favor
climbing |
| 12-27 |

Wheels And Tires
 Modern wonder wheels are veritable wings
for your bike.
Not too long ago, when you
bought a new road bike, you got fairly run-of-the-mill wheels comprised of
decent rims, spokes and hubs. These wheels were reliable and worked just fine.
But, they didn't really add any pizzazz to your new two-wheeler.
All that
has changed. Today, many if not most road bikes feature wheels that are marvels
of engineering. They're prettier, more aerodynamic, durable and lightweight,
sometimes superlight. Why is this important, you ask?
Because when you
cut wheel weight, you drastically improve a bike's climbing, acceleration and
handling. This happens because wheels are rotating weight. And this type of heft
is felt most by the rider. In fact, a few-hundred grams reduction at the wheels
feels more like a few pounds reduction. On the road, it's an amazing feeling,
like suddenly dropping 10 pounds of body weight.
Box vs. Aero Section
Rims One difference in these new wheels is rim type. There are two basic
designs named after their cross sections: conventional box-section rims (square
or rectagonally shaped) and aero-section rims (triangularly shaped).
Box-section rims are lightweight, accelerate quickly, and provide the
most comfort. Aero-shaped rims are stronger, have less wind drag, and are
stiffer (less comfortable). It's important to consider wheel feel when you're
test riding bikes. You might prefer one type to another.
When choosing a
rim or wheel type it's important to consider where and how you ride, as well as
how much you weigh. For example, a 140-pound rider who spins leisurely mostly on
rough pavement, will probably prefer a box-section rim for its additional
comfort. But, a competitive 200 pounder on smooth roads will much prefer the
stiffness and speed of aero-section hoops.
There are many wheelsets on
the market designed for general and specific types of riding. Most use minimal
spoke counts (traditional wheels have 32 spokes), which cuts wind drag and wheel
weight. Superlight wheels are excellent for climbing. Aero wheels are usually a
little heavier and intended to cheat the wind for an advantage during long rides
and time trials.
Tire Talk Bike companies use a variety of
different tires on their road models and usually, the tires are good for 1,000
to 2,000 miles, depending on your weight, riding style, and whether the tire is
located on the front or back. So, the chances are pretty good that you'll be
fine riding on the tires that come stock on your new bicycle.
You might
consider upgrading however, if the tires are the wrong size or design for your
predominant type of riding. One important difference is bead type. Beads are
found in both edges of the tire. They're the parts that grip the rim to hold the
tire on the wheel. Less-expensive tires use wire beads, which add weight
(remember that rotating weight is the most important kind). Better models have
Kevlar (a super-tough fabric) beads.
Tires with Kevlar beads are called
"folding tires," and they're a great upgrade if you want lightweight wheels and
lively handling. These tires cost more, so expect to pay for them. But, the
additional expense is worth it if you want optimum performance.
Another
reason to swap tires is to get a different width. Tire width determines how much
air it holds, which in turn decides ride softness. It also affects how the bike
handles, rolling resistance and durability.
You'll find the tire's size
written on its sidewall as "700 x XX," where XX is the tire's width in
millimeters (700 refers to the nominal outside tire diameter in millimeters, a
European standard called "700c"). We're happy to discuss tire differences with
you. Here's how the sizes compare:
| size |
what it's good
for |
| 700 x
20 |
thin, primarily for time trials and
lighter riders |
| 700 x
23 |
normal, for most conditions, racing and
training |
| 700 x
25 |
thicker, longer wearing, more shock
absorption |
| 700 x
28 |
thick, longest lasting, ideal for
touring, commuting, heavier
riders |
About 650c Wheels Some
time-trial bikes, as well as some compact, smaller models come equipped with
650c wheels, which are smaller diameter than 700s. These are a little lighter
and slightly stronger, and they accelerate faster than standard 700 wheels. But,
650c wheels sometimes ride a bit rougher (smaller, lighter riders can compensate
by dropping tire pressure slightly), lose momentum a bit faster and cover less
distance per revolution (strong riders will require taller gearing). So, if
you're comparing bikes with both wheel sizes, be sure to test ride them to feel
for yourself the differences. That's the best way to decide.
Component Groups
 30 gears. Foolproof bearings. Awesome
braking. Today's componentry will amaze you!
The two companies selling
road groups are Shimano and Campagnolo and each offers 5 different levels of
components. A group is comprised of brakes, hubs, chain, cassette, bottom
bracket, crank, derailleurs, shifters and headset (sometimes a seatpost is
included, too).
As you spend more money, parts get lighter and bearing
quality (bearings are what the hubs, headset, pedals and crankset spin on)
improves. Higher-level components shift and brake slightly better, too -- though
even entry-level braking and shifting is exceptional on modern systems.
So, how do you decide what to buy? It comes down to your price range and
which group offers the features you want (i.e. weight, number of gears,
appearance, quality). Usually, you can narrow it down to a couple of groups.
And, at that point, a great way to decide is to ride and compare. If you can
feel a difference in braking and shifting, go with the bike you like
better.

Shopping Tips
We're looking forward to helping you select
the perfect road bike.
Price
Particulars We've asked you to think about what you'd like in a bike and
what you'd be comfortable spending. Now that you have an idea how to decide what
type of road machine to get, it's time to come into our store and do some tire
kicking and test riding to see how the models compare in person. This will
complete the picture and give you a chance to see what you get at the various
price points. Here are a final few helpful tips:
Shopping
Guidelines
Buy once. It's less expensive to get the frame, wheels and components you
want initially than to upgrade later.
Proper fit is much more important than getting a good deal. And only by
coming in to see us can we size you and ensure that you're looking at the right
size bicycles. As one master framebuilder says, "Anyone who suggests that you
can be fit over the phone or internet is just demonstrating their
misunderstanding of the topic."
Be wary if a deal sounds too good to be true. Manufacturers pack as much
value as they can into each bike model. But, they also want to sell things.
Sometimes compromises are made in component specification or frame quality to
reach a more attractive price point. If a bike you're interested in has parts or
features that appear to be uncharacteristic for its price, try to figure out
what corners were cut. Or ask, and we'll explain.
Pick out the features and components that best meet your needs, then see
what the bike costs. This way you'll know if your performance expectations match
your budget.
Be prepared to spend a little extra because usually you'll want a few
important accessories with a new bike such as a water bottle and cage, a
cyclo-computer, a new helmet, etc.
