Giant Trance 27.5 4 Black/White
Ride aggressive lines. Float up technical climbs. Trance 27.5 smoothes out rough trails and keeps you in control.
At the core of this trail-devouring machine is an ALUXX SL frameset, the lightest alloy 5.5-inch/140mm travel full suspension bike ever made by Giant. Radically hydroformed with the latest lightweight co-pivot suspension design, the Trance 27.5 frameset pushes aluminum full suspension bike technology to new limits of weight, strength and performance.

Vikt 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 Maestro suspension
Whatever off-road adventures you seek, Giant's Maestro Suspension helps you make the most of your efforts. Control, traction, comfort, speed—you get more of everything with Maestro. From fast and efficient 4-inch-travel XC to full 8-inch DH bikes, Maestro is an adaptable system that offers smooth, active rear suspension on all types of terrain.
Whether you’re sprinting up a climb or coasting through a rock garden, Maestro Suspension performs consistently under pedaling power and doesn’t compromise efficiency.
Complete suspension activity
From high-frequency trail vibrations to heavy-hitting compressions, Maestro Suspension soaks up the full spectrum of trail impacts.
Total brake independence
Even under full braking force, Maestro Suspension remains fully active and reactive.
The Aluxx advantage
From the manipulation of atomic grain structures to our advanced forming and welding techniques, Giant has been at the forefront of aluminum engineering for more than 30 years. Today, ALUXX Aluminum Technology represents the pinnacle of alloy performance. A heritage of craftsmanship combined with unmatched manufacturing capabilities gives Giant the unique ability to monitor every step of the aluminum frame-building process. Through our cutting-edge materials science, proprietary forming techniques, and attention to detail, we are constantly advancing aluminum performance to create bikes that are lighter, stronger and stiffer. The difference can be felt in the ride. Every aluminum bike bearing the ALUXX Aluminum Technology label must live up to the highest standards and meet the tightest tolerances of any aluminum frame in the world.

Giant 27.5 wheel technology
Superior performance without compromise. These are the reasons to ride Giant 27.5:
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.
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.
Lighter wheels/tires result in a quicker acceleration and lighter overall bike weight - a win-win combination.
Snappier acceleration and a reduced angle of attack for a smoother, more agile ride.
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.
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.
A larger tire contact patch, increased stiffness, and optimized frame geometry improve traction, braking and handling.
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.
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.
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.
