Road Bike - Tire Pressure

2008-06-14T07:03:00.000-07:00

Proper tire pressure is very important! Too little air in your tires greatly increases the likelihood of getting "compression cuts", which are caused by bottoming out the tire on the rim when hitting a bump. These punctures are easily identified by the type of damage to the tube: a thin slit (sometimes two parallel slits) running lengthwise along the tube.

Too low pressure also greatly increases rolling resistance, meaning that you have to pedal a lot harder to go the same speed. In addition, since air literally cushions your bike's components, low tire pressure accelerates wear and tear on your frame, fork and wheel parts. Too much pressure may cause the tire to want to blow off the rim as well as giving you a harsh ride.

Chain Reaction recommends always running your tires at the pressure rating listed on the sidewall of the tire. Unlike mountain bikes, road bike tires have a narrow range of acceptable pressure, making it essential that you check for the right amount of air before every ride! We suggest either a separate pressure gauge ($3.95-$14.95) or a pump with a built-in gauge

Road Bike - Gear Shifting Components

Before we go into detail about how to shift gears on your Mountain Bike, it should be first explained what the Mountain Bike Gear Shifting System Components are. This to give you an idea what happens technically if you shift gears; if you understand how the gears work, shifting gears will be something that comes natural instead of a thing that you should memorize.

The crank which is bolted onto the bottom bracket consists of three chain-rings. Chain Rings are bolted into the cranks. They come in three size ranges. The big ring (48-42 teeth), the middle ring (36-32 teeth), and the small or "granny ring" (26-20 teeth).

The "sprockets" or "cogs" are found in the rear hub. Modern sprockets consist of 7-9 size ranges from 36-11 teeth. Normally, the 7 & 9 speed sprockets have the same heavy and light gear. The difference is in the mid-range gears. The 9-speed sprocket has more mid-range speed which lessens the change in speed upon up or down shift.

Do you like to ride fast as lightning? Are you interested in riding on streets and sidewalks but not rugged trails? Then I have the perfect bike for you - the Road Bike.

The main thing the road bike built for is speed. The road bike is similar to the bikes that race in the Tour de France. Don't you want to be like a famous bike rider in the tour de France? If you do, go out and buy a road bike! It can be used for a race or just riding around in the park. It is more of a modern 10 speed and a lot safer. If you can't afford to buy a Mountain bike or hybrids, go out and buy a road bike. You'll be so happy with the light weight frame, drop bars and all the other things that you can get on the road bike.

Frame: The frame is very light. It has a narrow seat. The frame is usually aluminum, carbon or titanium.

Gears: To change gears you push a lever under the brakes to change gears. That makes changing gears really easy. Keep your gear at a lower gear.

Tires: The tires are so strong that they could hold a bomb squad. The tires are less than an inch wide. If it is a rainy day the road bike has better traction than any other bike.

Brakes: The road bike has caliper brakes. The brakes are sensitive to small changes. The brakes don't have a lot of braking power.

Pedals: When you push the pedals you move the bike forward. The pedals have a lot of grip in case of rain or anything slippery.

Handle bars: Most road bikes have drop bars. The drop bars come in many different shapes. The drop bar allows you to have many different positions with your hands.

Tips on Buying a Bike

You’ve made the decision to buy a bike. Now it’s time to start seriously gathering information on how to select the best style for your needs and get a good fit. Here’s some tips that will help you purchase the right bike for your needs.

Know Your Type

First, you’ll need to decide what you want to use the bike for. Where will you be riding your bike most, on road, off road, or both? The answer will help you determine the type of bike to purchase. There are five basic types of bicycles in three categories that you need to be aware of:

Road Bikes.

They used to be known as the "ten-speed," however road bikes now range from 12 to 21 speed. Within this category of bikes are touring, racing, and sport bikes.

Touring Bike.

This bike is not built for speed, rather, it’s designed to provide comfort for the long haul. A touring bike is an excellent bike for long distance riding. The drop handlebars provide comfort, good control and allow for multiple hand positions. Twenty one speeds will take you over any type of incline you’ll encounter and cantilever brakes can stop you even when you’re heavily loaded down.

Racing Bike.

This bike is built for speed, sporting an aerodynamic, thin and ultralight frame. A short wheelbase allows the bike to respond to the slightest movements and 12 or 18 gears will get you, and keep you, at top speed. If you’re into winning races, this is the bike for you.

Sport Bike.

This bike falls between the touring and racing bike. Not as light as a racing bike but more responsive than the touring bike. The sport bike’s drop handlebars provide comfort and control and the aerodynamic design allows for faster speeds. If you’re into taking rides of 10 or more miles while turning up the intensity by adding some speed, this bike can take you there.

Mountain or All Terrain Bike.

This bike is rugged. Built with a sturdy frame, straight handlebars and fat, knobby tires, it can tackle the rigors of off road riding. The upright riding position on the bike makes it comfortable while giving you leverage for steep inclines.

Hybrid Bike.

This bike is a cross between the road bike and mountain bike. It’s lighter than a mountain bike, but not as fast as a road bike. Straight handlebars, medium-width tires, 21 gears, and upright riding position makes the bike perfect for short distances, running errands or commuting.

The Perfect Fit

Once you know which type bike you want, make sure the bike you select fits you properly. There’s essentially two ways to accomplish a good fit. If you want a perfect fit, for about $50, have a quality bicycle shop calculate your bike size using a computerized program called the Fit Kit. They’ll take various measurements such as, length of your legs, torso and arms then give you a printout of your measurements and which frame height and length best suits your body.

The second best way to get a good bike fit is to follow these guidelines:

Frame Height.

Straddle the bike. You should have one to two inches of clearance between the top bar of the bike and your crotch, three to four inches if you’re going to be riding on off-road terrain. If you want to be a little more exact, measure your inseam, straddle the bike, pick it up until the top bar touches your crotch, then measure the distance between the bottom of the tires and ground.

Frame Lengths.

Be sure when you sit on the bike you can comfortably reach the handlebars. If the handlebars are too far away you won’t have adequate control, if they’re too close you’ll be uncomfortable and tire easily.

Seat and Handlebar Adjustment.

A quality bike shop will make the necessary adjustments for you to fine tune the fit of the bike. A critical adjustment is seat height. Your knee should have a 25-30 degree bend when the ball of your foot is on the pedal at its lowest position. The handlebars should be one inch lower than, or the same height as, the seat. Check to be sure you can comfortably reach the brakes and that the width of the handlebars are approximately the width of your shoulders.

Take a Test Ride.

Just like purchasing a car, this is where the rubber meets the road. You should feel comfortable and in control. Your elbows should be relaxed with a slight bend and squeezing the brake levers should be easily accomplished. Slide your rear back off the saddle, stand up on the pedals, flex and round your back, and move your hands to various positions on the handlebars to assure you can move around on the bike easily while it’s in motion.

Accessorize

Once you select the bike to purchase, you’ll want to get some accessories to go with it. Most important is a helmet. You may also want to consider a tire pump, tube repair kit, pressure gauge, seat pack, water bottle and cage and a lock. The bicycle shop can help you select these and install them on your bike. Depending on how much you spend on your bike, you may be able to convince the salesperson to throw in some of the accessories at no charge.

Enjoy the ride.
