Unheard of Price for This Level Of Tech. Get Thru-Axle, Boost Full Suspension w/Lockout Forks. MONSTER 27PLUS x THREE INCH SUPER WIDE TIRES!*
If you have ridden one you know why you want one. If you have ever wanted to try one, this is the best deal; spec for price anywhere on a 27PLUS 5INCH TRAVEL Full Suspension FATbike with BOOST Hub Spacing. Extremely capable with Hydraulic Disc Brakes- rated by magazines as the best - Way better than v-brake systems and more powerful. (*different tires require different whls/tires you provide)

SWEET HANDLING TOP TECH, KINESIS ENGINEERED DESIGN
Co-designed by Kinesis and Gravity. Kinesis is one of the best frame designers and factory in the bike industry. Features an Advanced HydroFormed aluminum frame + Advanced Suspension Fork with FRONT LOCKOUT and THRUAXLES Front and Rear with Top Rated, trail-ready geometry.

Advanced Single Pivot Full Suspension Technology with LEAPP (Linear Extended Axle PivotPath):
Features the most advanced and durable single pivot design we've seen to date. Single Pivot designs tend to be Lighter and more durable, less maintenance than most competing multi-link designs. LEAPP = Linear Extended Axle Pivot Path, the downtube mount of the rear suspension is designed to extend the main pivot point further forwards which creates a more vertical rear axle path= smoother suspension action.

Trail Commanding Performance: SUPER SHORT Chainstays PLUS Slack Head Angles. Fully modern design with sleek internal cable routing and compatible with StealthType internal routed dropper seatposts.

What is Boost: Boost is a new dropout standard designed to widen the hubs on the previous standard MTB spacing wheels. The rear axle is wider by 6mm to 148mm and the front axle by 10mm to 110mm. Wider flanges = wider bracing angle for spokes = a stronger and stiffer wheel. Allows the use of 29er wheels with higher strength and stiffness for top performance. Also, More tire clearance, ability to use 27PLUS tires and with shorter chainstays for superior handling and climbing.
NOTE: This is a brand new factory direct model with the newest features and not yet on the Gravity USA site

27.5PLUS VS 29er
27Plus is lighter and more nimble than a normal fat bike and roll over obstacles better most any other tire size. Fits smaller riders than the 29ers too. The 27.5 PLUS / Mid Fat mountain bikes will have the best of all worlds. The agility of the 26" wheel and the big wheel experience of the 29er mountain bikes with the cushion, super grip and flotation of a fat bike. Larger and Heavier riders benefit from the extra air volume in the 27PLUS tires.

29er version accelerates and rolls faster but not as much flotation over soft surfaces as the 27PLUS.

COMPETITION READY
Specified with competition-ready components and has geometry based on careful research and trail-testing. Please compare this bike directly against any other manufacturers SRAM EAGLE 1X12 equipped $2700+ 27.5PLUS capable Full Suspension bikes on the market. Their bikes are likely heavier or not as well equipped or not 27PLUS capable or Not Boost spacing. They certainly will cost you hundreds more.

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.
