GT Timberline 1 - 29er Bike

The one bike that does it all. Are you driving yourself crazy trying to decide between a rugged trail-ready bike and something reliable to commute around town on? Who says you can’t have just one bike that does it all? The Timberline spans the gap between the two so you get the best of both worlds: durability and control on the trail with the comfort and dependability on the road that GT is known for.

  • Independent drivetrain™: This suspension does its job. Period. Because it operates independently of the drivetrain, the suspension can focus solely on its intended purpose – a smoother, faster ride – without making compromises in pedaling efficiency. And because it’s an inherently simple design, it’s easy to set up, ride and maintain. Sound good? Good.
  • Triple triangle™: Originally developed to extend the frame life, stiffen the rear triangle and thus create a faster, more responsive ride, the triple triangle™ frame has transcended its role as just another tech story and become an iconic symbol of who we are and what we stand for.
  • Forged elements: We forge every single linkage and pivot on all of our dual-suspension bikes. We also forge areas of the frame that are prone to stress or abuse, such as head tubes, bottom brackets and dropouts.
  • 1 1⁄8" x 1 1⁄8" head tube: Light on grams, not on performance. These forged construction head tubes are as capable of handling marathon trail sessions as they are of chasing points on the xc pro circuit.
