XC speed meets aggressive trail riding stability with Giant's Anthem Advanced SX 27.5. The Advanced-grade composite frame with ALUXX SL rear triangle creates a nimble feel that's fast on the climbs and smooth on the descents. 100mm of travel courtesy of RockShox's Monarch RT DebonAir shock keeps rear wheel traction pegged, while the RockShox Revelation RL with 120mm of travel up front takes on the big hits and the chatter with equal ease. 27.5-inch Giant composite wheels are nimble enough for weaving technical lines and big enough to steamroll everything else, and they're wrapped in Schwalbe rubber for sticking the corners. A trail chameleon like this needs a drivetrain that can handle the ups, downs, and everything in between, which is why a SRAM X01 powerhouse adorns this rig. And with all that speed, you'll need reliable brakes that can modulate, so Avid's Guide RS discs are on the case. A Giant Contact SL Switch-R dropper post lets you get into the best descending position possible, too.

Giant’s OverDrive 2 delivers up to 30%-better cornering and sprinting stiffness and control than non-tapered front ends with:
1/2) 1 ¼-inch/1 ½-inch diameter bearings
3) 1 ¼-inch diameter Giant stem
4) Tapered fork steerer
5) Giant OverDrive steerer plug

27.5-inch wheels (also known as 650B) offer the best characteristics of 26- and 29-inch wheels for an outstanding ride.

27.5-Inch (650B) wheel/tire performance.

Efficiency: Increasing the wheel diameter decreases the angle of attack (the angle at which round objects meet square objects). The lower the angle, the easier it is to roll over obstacles and maintain momentum.

Traction: With a larger diameter, the tire's contact patch increases, putting more rubber on the trail. A 27.5-inch (650B) has nearly the same contact patch as a 29er for superb acceleration, braking and cornering.

Weight: The weight of a 27.5 wheel, tire and tube is only 5% more than an identically built 26-inch wheel. Compare this to a 12% increase with a 29-inch wheel. Lighter wheels mean a lighter bike, and better climbing and acceleration.
