If you have ridden one you know why you want one. If you have ever wanted to try one, this is a great deal on a SRAM 1x10 shifting, 27.5" Mountain Bike with Shimano Hydraulic Disc Brakes & Suntour Front Shock w/ Lockout.

The Gravity HD 1by10 is specified with competition-ready components and has geometry based on careful research and trail-testing. Please compare this bike directly against any other manufacturers $1399+ 27.5" hardtail on the market. Their bikes are heavier or not as well equipped.

With a Suntour XCT Front Shock w/ Lockout, the HD 1by10 adds to those race winning specs; a smooth shifting Samox 1x10 crank, VP headset, sweet shifting SRAM derailleurs with 27.5" DoubleWall Wheelset and Shimano Hydraulic Disc Brake system. (Hydraulic Disc Brakes are rated by magazines as the best)

This bike is lighter than most any other bike in its price range & has much higher level parts.

Gravity has really dialed in a race-proven geometry into this phenomenal ride. The handling is very responsive and yet stable. Singletrack and switchbacks are all handled with ease. Slow speed and high speed, technical and flat-out hammering, you will go faster because this bike is so capable. If you love the ride of the Gary Fisher Marlin, Cobia or Mamba, you will love the ride of this Gravity bike.

This model is also available in a 29" wheel version (listed separately)
