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.

Wheels And Tires


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 light, sometimes super light. 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 light, 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 XXc," 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.

Frame And Fork Materials


Although over the years there have been such oddities as bamboo (still available!) 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 shapes, 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 seat tube or down tube. Sometimes manufacturers provide these and they usually help 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, while there are new steels almost impervious to corrosion, most types can rust if treated carelessly (protect that paint job!).

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 and straight-gauge tubes compared to the fancier lug construction and butted tubes (varying tube wall thicknesses) 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.

You may hear that aluminum has a more jarring ride than the other frame 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 most steels, 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 super-light tubesets such as Easton's 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 good vibration damping to smooth the ride.

Titanium
Titanium (also called "ti") is one of the longest lasting, strongest, and most expensive frame materials. Some 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.

Titanium forks are rare and 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," "composite" and "graphite") is unique because it's not a metal. It starts out as a fabric that's impregnated with a glue called resin. The resulting material can be turning into tubes or shaped in molds and is usually cured with pressure and heat turning the material into a solid structure. Frames made of carbon are extremely light, stiff and durable.

Carbon's greatest advantage is that it 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, so it's possible to achieve supreme lightness with outstanding rigidity and top-notch compliance for comfort, too. What's more, carbon is 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 in high demand by other industries, carbon frames can be 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 because there are some amazing designs and we enjoy showing them off.

Carbon is a popular material for forks due to its natural ability to absorb shock while offering fine handling. There are even all-carbon forks (weighing less than a pound). These are great if you want a super-light road bike. (There are other carbon forks that use steel or aluminum for the steerer.)

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 30-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 choices. 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.
