Join the 29er Revolution
If you have ridden one you know why you want one. If you have ever wanted to try one, this is the best deal on a Single Speed drivetrain equipped 29er bike with powerful Disc Brakes and CrMo StraightBlade fork.

Specified with competition-ready components and has geometry based on careful research and trail-testing. Please compare this bike directly against any other manufacturers $800+ 29er singlespeed on the market. Their bikes are likely heavier or not as well equipped.

Extremely capable
Disc Brakes are rated by magazines as the best - Way better than v-brake systems and more powerful.

This bike is lighter than most any other bike in its price range AND 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 29er bike.

How Can We Sell At This Price?
We sell Factory Direct so you pay a price close to what a local dealer would pay at wholesale cost for a comparably equipped bike. Thus, you get a better equipped bike for hundreds less - often saving up to 60% off List prices. The only thing you have to do is a bit of tuning and assembly.

These 2020's are available. Get yours before they are all gone!
