This little but powerful trail bike, Faith (2025), is perfect for ambitious young riders. With a lightweight alloy frame, high-performance wheels, and youth-tuned suspension, it offers efficient climbing, excellent traction, and confident handling. It's the ideal bike for taking your trail skills to the next level!


FlexPoint rear suspension with a Giant Crest FloTrac Lite shock delivers 135mm of smooth travel tuned specifically for lighter weight riders. Up front, the 140mm Giant Crest SL FloTune Lite fork handles rocks, roots and ruts. Front and rear suspension both have minimal activation force, giving young riders smooth control and confidence on technical trails.


An ALUXX SL aluminum frameset with youth-specific trail geometry is combined with quality lightweight components to minimize weight and help young riders tackle challenging terrain. A new Giant TRA WheelSystem (27.5-inch front/26-inch rear) borrows key technologies from the proven adult TRA WheelSystem for improved climbing capabilities and quicker acceleration.


TRA WheelSystem with WideGuard technology results in lighter, stronger rims so riders can run lower tire pressures for better traction without the risk of tire punctures or rim damage. The mixed wheel setup combines the agile handling of the 26-inch rear wheel with the improved rollover capabilities of the 27.5-inch front, while a dropper seatpost makes it easy to optimize riding position while climbing or descending.
