Giant Mountain Bikes: Big on the Trail

Many expensive branded things turn out to be disappointing. When it comes to high-risk recreational vehicles like mountain bikes, falling short of expectations may not only be "disappointing," but possibly even life-threatening! Thankfully, consumers help each other decide which brands are good and which are not and avoid fatal pitfalls, by placing certain labels higher than others in terms of purchase priority. Giant mountain bikes sell a lot, and are considered top of the line. Are they worth the hype?

Well, if the many satisfied online reviewers are to be believed, they certainly are. There are currently hundreds of reviews for Giant mountain bikes on the popular bike review site, MTB Review (Mtbr.com). The Giant NRS line, in particular, has merited the "Freeride Choice Award," after getting close to a perfect 5 rating from an adequate number of reviewers. Talk about satisfying its costumers! Giant models are built to please, and they deliver.

Giant has developed models for different body sizes, so that women and kids may not feel excluded from its clientele. Another big thing (pun intended) about the Giant bike is that it places priority on manageable weight and speed. Ironically, given the brand name, a lot of the top-rated Giant bikes are lightweight and aerodynamic – all but streamlined to fly. The Giant NRS 2, for example, is considered light for a full-suspension machine. The slight weight difference between this model and its competitors makes all the difference for racing cyclists with a discriminating eye, and a drive to win.

Not to be pigeonholed, however, Giant is also recently branching out into making notable "muscle" bikes. The Trance line of bikes, fortified with the new "Maestro" rear suspension, is taking the place of the VT line. Before the Trance line came into the fore, the VT line received considerable praise from many users. Like the NRS, it received the "Freeride Choice Award." Some users may complain of excessive weight, but compared to the other features, it may prove to be an excellent deal. We have yet to hear from other Trance users on this.

Price may be a problem for the bargain hunter, but with brand names like Trek, Intense, Ellsworth and yes, the Giant, you get what you pay for – which is quality. You can surf the Web and see for yourself that various Giant mountain bikes are highly rated by a great many users, and for good reason.

Tips To Understanding The Basics Of Mountain Bike Gears And How They Work

Remember when you didn't think about the gears on your bike? Your bike had a bike sprocket connected to the pedals and a small sprocket connected to the back wheel an that's all you needed. Then you got a little older and got your first 10-speed. That bike had two sprockets up front and five on the back. In all likelihood, the shifters were a pair of levers connected to your bike frame near the handlebars. As time went on the shifters moved to the handlebars themselves and then became advanced-looking dials right beside the grips. And next thing you knew, instead of a paltry ten speeds on your bike, you were riding a 27-speed mountain climbing machine!

Why all these gears? To make riding faster and easier, of course. Whatever the number of gears your bike has, if it has 2 or more then there's a basic set-up which almost every bike employs.

First of all you have your front and rear sprockets. These, along with the chain, form the most basic components of the gearing system. To determine your gear ratio you compare the number of teeth on the front sprocket to the number of teeth on the rear sprocket.

If your front sprocket has 52 teeth, and your rear sprocket has 20 teeth, then you're looking at a ratio of 2.6. The higher the ratio the faster the gear. Typically the gears on the front, starting from the inside, get larger as you move out. On the back wheel, though, the largest gear is typically the farthest inside and they get smaller as you move out.

The next key component for your mountain bikes gears is the derailleur, or derailer. The derailleur is what moves the bicycle chain from gear to gear. A typical shifting system employs both a front and rear derailleur. Without the derailleur you wouldn't be able to shift gears. The derailleur consists of pulleys and the cage, which is the part which actually comes into contact with the chain. The pulleys are attached to the gear cables. There are separate cables for the front and rear derailleurs. The gear cables connect to the gear shifters.

There are a variety of gear shifters available today and they cover a wide price range. The gear shifter is what allows you to change gears. The first type of shifters were levers known as friction shifters. These worked simply by pulling the cables attached to the derailleurs.

Friction shifters can be troubling because the way they're designed you can easily get caught between gears and accidentally damage your gears or even wreck. The more advanced variety of shifter is known as the index shifter.

Index shifters have specific stopping points and are calibrated to perfectly shift from gear to gear. They remedy the drawbacks of the older friction shifters. Gear shifters may be placed anywhere from the frame to the handlebar base to the grips to models which seem to be part of the brake levers.

Mountain bikes have multiple gears to make it easier for you to negotiate difficult terrain. Higher gears are there to help you speed downhill or across the flats, and lower gears are there to help you surmount those difficult inclines. Remember, it's best to shift gears when you're not putting a lot of stress on your pedals. Shifting when there's heavy pressure on the pedals can damage your shifting system.

The Intricacies Of Mountain Bike Gears

When you choose mountain bike, it is a good idea to learn more about the gearing systems. This article will explain more about how those systems work.
Mountain bike gears are continually becoming more and more complicated and intricate. Today's bikes can come with up to 27 gear ratios. It is common for a mountain bike today to use nine gears in the back and three sprockets of different sizes in the front for gear ration production.
Why so many gears? The most common reason is that a large number of gears allow a rider to pedal at the same pace no matter what terrain that he/she is on. This can be understood better if you think about a bike that just has one gear. Every time you turn the pedals one full turn, then the rear wheel also turns one full turn, too (1:1 gear ratio).
For example, your back wheel is measured at 26 inches. If you pedal one full turn, then this would mean that your wheel moved 81.6 inches. If you are riding at 50 RPM, then you will be able to go 340 feet per minute. This means that you were going 3.8MPH, which is equivalent to walking speed. This speed is great for going up a hill that is steep, but it is not a good speed for flat ground or racing downhill.
If you want your bike to go quicker, then you will need a different ratio. If you want to reach a speed of 25 MPH downhill using a 50-RPM cadence, then you will need to have a 5.6:1 gear ration. If you have lots of gears on your bike, then you will be able to get that ratio so that you can continue your pedaling at a consistent pace, no matter what terrain you are on or what your speed is.
A typical mountain bike that has 27 gears will have six gears so incrementally close to the other that you will not be able to determine that there is any difference between the gears when you change them.
Most mountain bike riders decide to choose a gear system with a front socket that is suitable for the slope or terrain that they usually ride on and they stay with this choice, even though it may be more difficult under a heavy load to shift the gears. This is purely a personal decision, but it is simpler to shift between gears when the rear socket, rather than the front one.
When you are pedaling uphill, then you will find that it is much better to choose a sprocket that is smaller on the front and then shift gears with the nine gears that are available on the rear. If you are more speeds on the rear sprocket, then you will find that it is much more efficient to ride.
Mountain biking needs gears so that you can keep an overall speed going. If you didn't have gears, then you would find it difficult to build up any speed and you would find it nearly impossible to pound your pedals for extra control. Gears help to move the pedals and enable you to gain that speed.

Your Mountain Bike Needs a Little Lovin’ Too…how to Care for your Bike!

When you’re out on the trail, miles and miles from home, you don’t want any serious mechanical situations occurring with your bike. Pushing your bike up and down steep, slippery slopes is not what mountain biking is all about. You want a fun, exhilarating ride, and the best way to ensure this is by keeping your bike in good mechanical order. Here we look at a few things you should do to keep your bike in shape. Clean your bike after each ride

When you’re out all day on the trail, you’re bound to get dirty, and so is your bike. While you might not mind staying dirty for a while, your bike does. When you get back to camp or when you load your bike into your car, give it a quick clean with some spare water. If your bike is caked in mud, clean the excess gunk with a stick. When you get your bike home, give it a thorough clean. Take particular care in getting all the mechanical parts as clean as a whistle. Keeping your chain lubricated

Once you have cleaned all the crap off your mountain bike, then you need to lubricate the chain. A dry chain will eventually lead to big problems, including kinks and broken links. And Murphy’s Law clearly states that this will happen at the worst possible time, when you’re miles from anywhere. Before you lubricate the chain, make sure that it is clean. Also, clean the gear sprockets with a small brush. There are special chain lubricants available specifically designed for the rigors of mountain bike riding, so use these instead of a general purpose lubricant.Lubricating your brake cables

While we’re on the subject of lubrication, every now and then you should lubricate your brake cables. You don’t need to do this as often as your chain, but you should do it periodically. It’s really quite simple to do. Remove the cable from both the brake housing and the levers and then remove the cable from the plastic covering and lubricate the whole length of the cable before putting it all back again. If your brakes feel sticky, then this may be all you need to do to fix it. Adjusting your brakes

Your brakes can really come in handy when you’re on a big downhill ride, so the last thing you want is for them not to be working properly. Before going on a ride, always check your brakes are properly adjusted. Firstly, if you have cantilever or V-type brakes, check that your brake pads are not too worn and that they are adjusted properly. If they need replacing, then do so. It may be a good idea to have some spares just in case. Alternatively, they may just need a little adjusting which is a simple procedure. It may just be a little fiddly and may require some trial and error. Next, adjust the cable from the brake and then do the fine tuning from the handlebar brake levers. If you have disc brakes, these will require a more complex service so you should closely follow the directions in your owner’s manual.

You should do a full service on your mountain bike periodically. The length of time between services will depend on how often, and how hard you ride, and the conditions in which you’re riding. If you enjoy spending time on your bike in the great outdoors, then you’ll need to be prepared to spend a little time with your bike in the garage as well.
