The Giant Sedona is a comfort bike that can be ridden both on- and off-road. Depending on the model, it has either a 21 or 24-speed drivetrain and a front suspension. The bike comes in extra small, small, medium and large sizes. Women-specific models are also available.

Finding comfort on longer rides can be a challenge, especially if you're using a racing bike. These bikes are designed to maximize efficiency, but that can come at the cost of comfort for less-experienced riders because the aggressive riding position is less than gentle on your body.

Disc brakes have become widely used for mountain biking because they provide effective stopping power in wet conditions. Unlike rubber pad brakes that provide friction against the rim of the wheel, disc brakes press ceramic or metal pads against a hardened-steel rotor to stop, which prevents brake slippage.

Although road bikes are commonly used in road cycling competition, the more specialized triathlon or time trial bike may give you the edge in shorter races.

Tubeless tires come with a few wonderful benefits for those who enjoy a riding experience on less-than-flat ground. In mountain biking, for example, the use of tubeless tires allows for a lower PSI rating, which will greatly improve your handling and performance over the harsh terrains you will explore.

Bell bike computers are devices designed to attach to your bicycle and record certain types of information, such as the distance you have traveled and the speed at which you move. A magnet and a sensor unit attached to the front of the bicycle track the movements of the front wheel.

Replacing the chain on your Schwinn bicycle can seem like a daunting task, but with the correct tool, the job is not too difficult. Chains for all bikes have the same core design, small links that join with pins. The old chain is one circular piece that must be disconnected.

Bike handlebars come in various designs, so the method required to remove them will vary depending on the type of bike you own. Newer bikes have a threadless stem for easy height adjustment. Older units have stems secured with locknuts that require a wrench to adjust the height of the handlebars.

If you're doing something like traveling with your bike, either by plane or having it shipped somewhere, you'll have to disassemble it before boxing it up. While you could pay a professional at your local bike shop to do this, it's fairly easy to do on your own.

Setting the proper height for your handlebars (and adjusting other bicycle components such as the seat and cranks) can help alleviate back, wrist and arm pain while riding, according to Boulder Community Hospital’s Center for Sports Medicine.

It was only a matter of time before mountain bike enthusiasts and road racers joined forces. When the weather around the country turned cold and wet and the road racing season ended, road cyclists took lightweight racing bikes with larger tire clearance and stronger brakes off-road, and cyclocross was born.

A Presta valve is a long, thin stem often found on the tires of high-end bikes. These valves work with a manual lock nut, as opposed the spring found on the traditional Schrader valve. Bike stores sell air pumps that can fit both valve styles or just one valve type.
