What is G-Volve Geometry?

Geometry is the DNA of how a bike rides. Two frames with identical suspension travel, identical components, and identical weight will feel completely different if their geometry differs. At DIRTLAB, we developed G-Volve — our geometry platform that gives riders the ability to tune their bike's handling character without compromising the fundamental design.

The Core Philosophy

Most bike brands design a single geometry per size and call it done. That works fine if every rider in that size range has the same riding style, rides the same terrain, and has the same preferences. But they don't. A 175 cm rider who races enduro in Whistler needs a fundamentally different setup than a 175 cm rider who rides technical XC in Taiwan.

G-Volve starts with a balanced baseline geometry optimized for all-around trail riding, then gives you adjustability at the key contact points that most influence handling: head angle, bottom bracket height, and effective chainstay length.

Adjustable Head Angle

G-Volve frames use a dual-position headset cup system that allows +/- 0.5 degrees of head angle adjustment without aftermarket parts. The low setting (slacker) increases stability at speed and in steep terrain. The high setting (steeper) quickens steering response for tighter trails and climbing-focused riding.

Half a degree might not sound like much, but the difference is immediately noticeable. At a typical 170 cm wheelbase, 0.5 degrees of head angle change shifts the front axle by approximately 8 mm — enough to change the balance point and steering feel significantly.

Geometry Flip Chip

At the rear of the frame, a geometry flip chip in the shock mount or dropout allows you to adjust bottom bracket height and effective chainstay length simultaneously. The high position raises the BB by 5-7 mm and shortens the chainstays by 3-4 mm — creating a more agile, playful feel. The low position drops the BB and lengthens the stays for maximum stability and cornering grip.

Combined with the headset adjustment, this gives you four distinct geometry configurations from a single frame — from "short and steep" for tight, technical XC trails to "long and slack" for aggressive enduro racing.

Why These Numbers Matter

  • Head Angle: Controls steering speed and high-speed stability. Slacker (63-64°) = more stable. Steeper (65-66°) = quicker turning.
  • Bottom Bracket Height: Affects center of gravity and cornering lean angle. Lower = more planted cornering, higher = more pedal clearance.
  • Chainstay Length: Influences rear wheel traction and front-rear weight balance. Shorter = more playful, longer = better climbing traction and stability.
  • Wheelbase: The sum of all the above. Longer = more stable at speed, shorter = more maneuverable in tight spaces.

Setting Up Your G-Volve Geometry

We ship every bike in the balanced mid-position. Ride it for a few weeks before changing anything — you need a baseline. Then, if you find yourself wanting more stability on your local terrain, go low and slack. If you want more agility and pop, go high and steep. The adjustments take 15 minutes with basic tools and are fully reversible.

Our geometry charts show all four configurations for every model and size. If you need help choosing, reach out — we're happy to recommend a setup based on your terrain and riding style.
