NOTE: Orange pic is of the smallest frame size to show shorter rider clearance. It has a very short seat tube so the rear stay and top tube must v down slightly to meet it.
Larger frames like the black pic above have progressively taller top tubes.
Larger frames cannot be made with same clearance as the smallest size for mtb riding. All traditional MTB frame styles are like this for these reasons

Join the 27.5 (650B) Evolution
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 27 Speed drivetrain equipped 27.5 (650B) bike with powerful Disc Brakes and 27.5" SUSPENSION FORK, SUNTOUR SF13-XCT-MLO-DS.

Why 27.5 (650B)?
You are lighter and more nimble than a 29er and roll over obstacles better than a 26er. Fits smaller riders than the 29ers too. The 27.5 mountain bikes will have the best of both worlds. The agility of the 26" wheel and the big wheel experience of the 29er mountain bikes.
26vs27.5vs29er Wheels



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 $900+ 27.5 (650B) mountain bike 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.

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

SWEET HANDLING
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 29er bikes like the Gary Fisher Marlin, Cobia or Mamba; you will love the ride of this Gravity 27FIVE G1 bike as it will be more nimble and roll about as well.

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.
