The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.

Giant 27.5 wheel technology

Superior performance without compromise. These are the reasons to ride Giant 27.5:

Lighter weight

Significantly lower bike and rotational wheel weight helps you climb faster with less effort.

Overall bike weight

Compare the weights of identically equipped bikes with different wheel sizes and you'll see substantial weight differences. As expected, the 26-inch-wheel bike is somewhat lighter than the 27.5, and substantially lighter than the 29 (up to two pounds of overall bike weight savings from 29 to 27.5). Every gram saved helps you ride faster.

Wheel/tire weight

The overall weight of a 27.5 wheel set (wheel, tire and inner tube) is only 5% greater than that of an identically built 26-inch wheel set. Compare this to the 12% increase of a 29-inch wheel set and you can see how a seemingly small increase in diameter results in substantial weight gain—and poorer performance when climbing or accelerating.

Weight comparison

Lighter wheels/tires result in a quicker acceleration and lighter overall bike weight - a win-win combination.

More efficient

Snappier acceleration and a reduced angle of attack for a smoother, more agile ride.

Rollover

Increased wheel diameter decreases the angle of attack (the angle in which a round object intersects a square object). This is a good thing. A 29-inch wheel rolls over a 6-centimeter square-edge obstacle 14% more efficiently than a 26-inch wheel does. In comparison, a 27.5-inch wheel rolls over the same obstacle 9.8% more efficiently than a 26-inch wheel does. Another way to analyze angle of attack is the degree of impact—where 26-inch equals X degree, 27.5 equals X-4 degrees and 29 equals X-6 degrees. Again, a shallower angle is better—so 29-inch takes the win, with 27.5 exhibiting nearly the same performance but without the weight penalty.

Acceleration

Arguably the most important benefit of 27.5 over 29 is quicker acceleration. This is the "snap" that a rider feels when they push hard on the pedals. It is affected not just by overall static weight but also where the weight is distributed throughout the wheel. The farther the weight is from the center of the hub, the slower the acceleration. So a similarly constructed 1000-gram 29-inch wheel is slower to accelerate than a 1000-gram 26-inch wheel—because the larger diameter rim and longer spokes place weight farther from the hub. The key to snappy acceleration is minimizing the weight of the outermost components (rim, nipples, spokes, tire, tube). As you can see, a 27.5-inch wheel is only 1.5% slower to accelerate than a similarly constructed 26-inch wheel, but a 29-inch wheel is 3.6% slower than a similarly constructed 26-inch wheel.

Better control

A larger tire contact patch, increased stiffness, and optimized frame geometry improve traction, braking and handling.

Traction

The larger the diameter of a wheel, the greater the contact patch of the tire. A larger contact patch results in better traction, which leads to improved acceleration, deceleration and cornering. As you can see, a 27.5-inch wheel has a similar contact patch to the 29.

Frame stiffness

Lateral (side-to-side) frame stiffness can be affected by wheel size. To accommodate larger wheels, frame dimensions must be elongated. Therefore, a size medium 29-inch wheel frame has more lateral flex (bottom bracket and headtube) than a size medium 27.5 or 26-inch wheel frameset. Additional flex compromises handling under heavy pedaling or sharp cornering.

Frame geometry

The larger the wheel, the more difficult it is to optimize geometry, especially on smaller frames. As the frame size decreases, headtube heights become higher (in relation to saddle height). On 26 or 27.5-inch frames, it's less of a problem, but geometry limitations can affect smaller 29-inch-wheel frames.

Unrivaled Composite technology

With more than 25 years of experience in carbon fiber engineering, plus a long history of rigorous development and testing with professional athletes, Giant is the industry leader in composite bicycle technology. To meet the needs of high-performance riders, Giant offers two grades: Advanced SL and Advanced Composite. Both feature unique materials, resin formulas and construction techniques.

Giant Advanced SL Composite technology

Giant's Professional-grade raw carbon material is woven in our own composite factory to create the most cutting-edge frames available today. These frames feature the most advanced engineering and construction methods:
>Professional-grade grade raw carbon with the highest stiffness-to-weight ratio available today.
>Professional-grade formula with Carbon Nanotube Technology (CNT), a microscopic polymer added to Giant's custom blended resin*. Like miniature buttresses, CNT strengthens the layers of composite. Frames featuring CNT are 14 percent more impact-resistant than those without it.
>Fusion process involves hand weaving the toptube and seattube together, then re-molding the area under heat and high pressure to unify the junction, resulting in a lighter, stronger frame than those with traditional molding.
>Continuos fiber technology manufacturing process allows Giant to construct the front triangle of Advanced SL bicycles* with larger, and therefore fewer, sections of composite material. With fewer pieces and junctions, the frames are up to 100 grams lighter and significantly stronger.
