GMC Topkick Dual-Suspension Mountain Bike Review Tuesday, January 24th, 2012


Whether you are an avid cycler or a seasoned mountain biker, the GMC Topkick Dual-Suspension Mountain Bike is the bike to have. It is an ideal choice for both rough city riding and trail riding. Its 26-inch full-suspension aluminum MTB frame is extra strong; it features a floating beam suspension design combined with a 65mm travel Zoom CH-386 suspension fork with elastomer/spring technology. This excellent suspension system allows a steady and smooth performance even on the toughest of terrains.

The GMC Topkick Dual-Suspension Mountain Bike features a 3 speed Falcon MF 31 T front derailleur and a 7 speed Shimano RD-TZ30GS SIS rear derailleur. This derailleur system makes up 21 speeds and the rear derailleur shifts smoothly with no jump clicks thanks to the Microshift push shifters. The bike is equipped with a set of strong aluminum wheel with 26 x 1.5 inch V-shaped alloy black rims, complete with a pair of Kenda black with yellow band 700 x 25C tires. It also features front and rear Promax disc brakes for smooth braking in any circumstance. Disc brakes are more superior compared to the usual rim brakes especially on unfavorable track condition.

Like any other GMC bikes, the GMC Topkick Dual-Suspension Mountain Bike is exceptionally sturdy, rugged, and comfortable for a long ride. It does not only offer superb performance, but it is also stylishly designed. Despite the superior features it has to offer, this mountain bike is surprisingly affordable. A brand new Topkick bike will only cost you somewhere around $450; note that prices vary between retailers. This is a good bargain, considering that other mountain bikes that feature similar Promax braking system can cost you more than $1000.

Despite all of its high-end features, the GMC Topkick Dual-Suspension Mountain Bike also has its share of drawbacks. The handle bar of this mountain bike cannot be adjusted without additional stem extender. The rear suspension system makes it difficult to buy accessories such as rear tray. As for the tires, the tire treads are a bit too rough to be used on regular city streets. This indicates that this bike is one of the types which are not really suitable for light riding. Weighing at 36 pounds, this bike is not exactly lightweight as well. If you are an inexperienced rider, you will likely face difficulty in controlling the bike especially when crossing across rough terrains. This bike is more recommended for professional mountain bikers.

Mountain Bike Parts – Gears and Derailleurs Tuesday, December 14th, 2010


Mountain bike parts serve to enhance the off-road cycling experience. There are many different parts of such a bicycle. Among the most basic are the gears.

The gears allow a bicyclist to keep a comfortable or maintainable pace no matter what the slope or speed. This pace is known as the cadence.

As time goes on, these off-road bikes continue to gain more and more gears. In fact, some today even have as many as twenty-seven ratios. These gear ratios are created through the various combinations of different sprockets. The typical layout is to have three of these located in front and nine located in back.

The gears are changed through the use of the derailleurs. These important mountain bike parts move the chain between sprockets as needed. There is a front one as well as a rear one.

The rear derailleur has two jobs to accomplish. The first is to ensure that the chain is always kept tense, regardless of the speed at which the rider is traveling. If the chain is on the largest front and back sprockets of the bicycle, the chain will naturally be more taught. If the chain is on the smallest sprockets of each, the rear derailleur has extra slack to manage.

The second task which the rear derailleur is faced with is that of switching gears. It does this by moving the bottom of the chain from side to side. It deals with the bottom rather than the top because that portion of the chain is under less tension. The force of the legs pedaling forward is what keeps the top under significant tension.

The front derailleur moves the chain between the front sprockets. It works with the top portion of the chain. As mentioned previously, this is under tension due to forward motion. In order to switch the front sprocket being used, it is necessary to ease off on the pedaling.

Sprockets are designed to hold and move the chain along smoothly. These mountain bike parts have developed to do more than that of course. Shorter and wider teeth as well as ramps and pegs are some of the elements used in sprocket technology to ease gear transitioning.
