The GMC Denali 700C Women's 21-Speed Road Bike is built around a lightweight aluminum 19.5-inch road bike frame. This model has the traditional dropped top tube women's configuration. You'll stop on a dime with the alloy calipers and brake levers, and the high-profile alloy Vitesse racing rims look as good as they perform. The Shimano derailleur and Shimano Revo shifts make it easy to change gears quickly and smoothly, and the high-performance 700c tires are up to the challenge of rigorous street racing. Lastly, this road bike will help you stay hydrated with the included alloy water bottle cage.pstrongSpecifications:/strongulliFrame: Aluminum 7005 straight gauge liFork: GMC Series 7000 steel liChain: KMC Z 51 liCrankset: Prowheel Alloy 335P6 28X38X48 170mm liFront Derailleur: Shimano FD-TZ 31 Index liRear Derailleur: Shimano RD-TZ30GS 7SPD liShifters: Shimano Revo SIS L2/R7 liBrake levers: Promax BL-250AP Aluminum liBrakes: Promax 501A Alloy Caliper Brake liRims: Vitesse Alloy black 700CX14GX36H liTires: Kenda Black With Grey Band 700X28C liStem: Aluminum black EXT:100mm 0D. liHandlebar: Maesbend W: 430mm D:22.0mm liSaddle: Cionlli Black liSeat post: HL Aluminum Micro Adjust 27.2 X 300mm liPedals: VP-990S plastic body with steel cage liWeight: 29.0 lbs /ulpstrongfont color=CC6600BIGAmazon.com Bicycle Buying Guide/BIG/font/strongbrstrongfont color=CC6600Finding the Right Bike/font/strongbr 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:pstrongfont color=CC6600The Right Ride/font/strongbr In general, bikes are broken down into three major categories:ullistrongRoad and Racing Bikes/strong--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. listrongMountain Bikes/strong--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. listrongComfort/Cruiser Bikes/strong--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. /ulpstrongfont color=CC6600The Right Price/font/strongbr A bike's price boils down to three essentials: frame materials, bike weight, and component quality and durability.ullistrongEntry-level/strong--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. listrongMid-range/strong--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. listrongHigh-end/strong--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./ulpstrongfont color=CC6600The Right Size/font/strongbr Fit is crucial for comfort, control, and proper power and endurance on a bike. Here are some basic bike fit tips:ullistrongStand-over Height/strong--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. listrongTop Tube Length/strong--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. listrongBikes for Women/strong--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. /ulpstrongfont color=CC6600The Right Accessories/font/strongbr When you make a bike purchase, don't forget these crucial add-ons:ulliHelmet (this is a must!) liSeat pack liLock liHydration pack, or water bottles and bottle cages liSpare tubes liPortable bike pump liGloves /ulp
