Product Description

The GMC Yukon XL is a lightweight road racing style bicycle featuring a 6061 Aluminum frame and aero fork. Alloy frames are not only lighter, but are torsionally stiffer and transfer pedaling energy more efficiently to the rear wheel. The Shimano STI Shifters with their integrated brake levers give you excellent control of shifting and braking. This puts gear changing and braking conveniently in one central location. The Yukon XL also sports a light and strong alloy wheelset and Kenda tires for superior traction and excellent braking response. Small Frame bike ; 20" or 51.0cm, Top Tube 52.5cm, Chain Stay 40.4cm, with a standover height of 30" or 75.5cm. Medium Frame bike; 22" or 56.0cm, Top Tube 55.5cm, Chain Stay 40.4cm with a standover height of 32" or 81.0cm.

Finding the Right Bike
To really enjoy cycling, it's important to find a bicycle that works for you. Here are some things to keep in mind when you're in the market for a new bike:

The Right Ride
In general, bikes are broken down into three major categories:

• Road and Racing Bikes--As a general rule, road and racing are built for speed and longer distances on paved surfaces. Thinner tires, lightweight 29-inch (700c) wheels and drop bars that allow for a more aerodynamic position are the norm. Most road bikes, regardless of price, offer many gears for tackling both hilly and flat terrain.
• Mountain Bikes--With their larger tires, hill-friendly gearing and upright position, mountain bikes are very popular for all types of riding, both on pavement and off. Mountain bikes that are designed specifically for rugged trail use typically feature a suspension fork. Some may have rear suspension, as well. A quick change of the tires on any mountain bike--even one that you use regularly on trails--adds to its versatility and makes it a worthy street machine.
• Comfort/Cruiser Bikes--For tooling around on bike paths, light trails, or for cruising a quiet beach-side lane, comfort/cruiser bikes are the ticket. With a super-relaxed riding position, padded seats, and limited or no gearing, these bikes are made for enjoying the scenery and having fun with the family.

The Right Price
A bike's price boils down to three essentials: frame materials, bike weight, and component quality and durability.

• Entry-level--You'll find a wide range of comfort and cruiser bikes in this category, as well as some lower-end mountain bikes and road bikes. Most will have steel frames and components that are designed to last for several years with frequent use.
• Mid-range--Bikes in this range may feature a lighter aluminum frame with mid-range components that keep performing after miles of use. If you're looking for a quality bike that is relatively lightweight and will stand up to abuse, this is the "sweet spot." Most serious commuter and touring bikes fall into this category, as do mid-range mountain bikes with a decent front suspension.
• High-end--Racers and serious enthusiasts who expect lightweight, high-performance components will want to stick to this category. For road bikes, exotic frame materials (carbon fiber, titanium) and ultra-lightweight components can add thousands to the price tag. Mountain bikes in this class often feature advanced front and rear suspension technology, as well as components designed to handle lots of rugged trail action.

The Right Size
Fit is crucial for comfort, control, and proper power and endurance on a bike. Here are some basic bike fit tips:

• Stand-over Height--To find out if a bike's overall height fits your body, measure your inseam. Next, determine how much clearance you'll need between your crotch and the top tube of the bike. For a mountain bike, you'll want three to five inches of clearance. A road bike should offer between one and two inches of clearance, while a commuter bike should have two to four inches. Compare the stand-over height for a given bike to your measurements (inseam + clearance) to determine the right bike height.
• Top Tube Length--You can measure your torso to get a good estimate of proper top tube length. First, make a fist and extend your arm. Measure from the center of your fist to the end of your collarbone (the part that intersects your shoulder). Next, measure your torso by placing a book against your crotch with the spine facing up. Measure from the spine to the bottom of your throat (the spot between your collarbones). Finally, add the two measurements (arm length + torso length), divide the number in half and subtract six inches. This is your approximate top tube length. Compare this number to a bike's posted top tube length. You can allow for about two inches longer or shorter, as most bikes can be adjusted via stem length/height and saddle fore/aft position to make fine adjustments to the fit.
• Bikes for Women--Proportionally, women tend to have a shorter torso and longer legs than men. Bike makers design women's bikes that offer a shorter top tube and many comfort/cruiser bikes built for women may also provide more stand-over clearance.

The Right Accessories
When you make a bike purchase, don't forget these crucial add-ons:

• Helmet (this is a must!)
• Seat pack
• Lock
• Hydration pack, or water bottles and bottle cages
• Spare tubes
• Portable bike pump
• Gloves

Customer Reviews

Good Value
I commend Kent for producing an affortable road bike. The lowest priced road bike with Sora STI shifters cost $650. There are some cost-saving measures to get to this price point: bolted rear wheel, a threaded headset (vesus lighter threadless (Aheadset) headsets), use of low end mtb derailleurs, non-carbon fork. However, none of these features are really that important. The wheels are light, STI shifting is great, and the derailleurs shift well. The weight of 26 lbs is a little more than the typical 22 lbs for a $650 road bike. But the crucial weight is in the wheels, and the wheels are comparable to a $650 bike. The other notable negative is that you have to assemble it yourself, and may not achieve the fine tuning of a bike store.

Still, if you are handy, this is an amazing value, and you'll surely keep up with another road biker on a pricier bike with equal conditioning.

Suggest you change out the pedals to clipless for efficient cycling.

Great value bike ...
This bike is a super value. The integrated Sora STI brake/shift mechanism alone when purchased separately costs over a hundred bucks. The bike is of course heavy at 26 lbs when compared to those with composite or titanium frames and forks. But with excellent physical fitness, one cannot avoid the feeling of worthy satisfaction when one zips by ahead of those poorly conditioned bikers commonly seen saddled on extremely more expensive bikes and sporting those USPS, Discovery Channel and other fancy jerseys. The only drawback about buying this bike is that it only comes partially assembled. As a result, aside from the unavoidable task of putting the machine together one can also chance upon getting an inadequately tuned bike, like I did. The bike I got refused to shift the chain from the small to the big chainring. No problem because I have done a lot of derailleur adjustments in my lifetime; it was just a matter of putting the front and rear derailleur levers in high gear settings, letting the chain rest on the big chainring and the smallest cog, tightening the cable while the derailleur cage is positioned dead center to the chain, and turning the two derailleur adjustment screws to provide the right space/limits for the sideway movement of the cage. But for a person just newly introduced to the machine, it can prove to be a real big downer. The bike is made up of very decent components. Its aluminum frame and fork are not the best material in dissipating road shock; on the other hand, the material is just so inexpensive and higly durable. Aside from that, with the proper tire pressure and good riding technique road shock can easily be minimized. If one measures potential miles per dollar, and not snob appeal, in arriving at an intelligent decision to buy a bike, this is an excellent choice. I got this bike for diversion purposes from my regular marathon training. And from its smooth performance, the diversion has so far been fun.

Sora shifters are hard to reach
The bike is perfect, except for the shifters. I have regular size hand and find shifting with the sora shifters somewhat difficult (though it is getting better with time).

The rear hub is not quick release (despite the Amazon description saying so) - not a big deal (actually it makes adjusting the hub easier)

The spokes on the front wheel and the rear wheel use diferent wrench size (#0 and #2).
