Giant's ridiculously fast Anthem Advanced 27.5 maximizes the uphills to then crush the downs! This carbon and aluminum race rig boasts Giant's Maestro suspension and a RockShox Monarch RL shock to devour rough terrain with 100mm of travel. A tapered OverDrive 2 head tube ensures a true-tracking front end for maximum cornering and downhill prowess. And of course, the Advanced-Grade Composite frame dispenses with all unnecessary weight so you build up a featherweight rig that's still tough as nails.
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.
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.
