Technology
Every DIRTLAB frame is built on four technology pillars. Each one is documented with real engineering data — no marketing abstractions.
The Four Pillars
K-Volve — Kinematics
How the suspension moves. Concentric pivot architecture delivering 97.3% anti-squat, ~100% anti-rise, 3.0–3.5° pedal kickback, flat leverage ratio, and a two-phase axle path. Five metrics optimised simultaneously — no competitor matches all five.
G-Volve — Geometry
How the frame is proportioned. 63° head angle, 77.8° STA, reach-based sizing, 10mm taller head tubes to eliminate spacer stacking. Every dimension calculated before it is cut. Geometry changes with travel configuration — all documented.
S-Volve — Sizing
How the frame fits the rider. Reach-based sizing with proportionally scaled geometry across S/M/L. Combined with the RA Reach Adjust headset for ±5mm fine-tuning within each size — 15mm total range without changing any other geometry parameter.
Maxon Bikedrive AIR S
Swiss precision motor integration. The lightest motor system in its class, T47 bottom bracket mount, removable battery, silent operation. Engineered for the Paratu CP platform from the beginning — not retrofitted.
Deep-Dive: Kinematic Metrics
Each kinematic metric has its own page with full engineering analysis, competitor comparisons, and real data from the Paratu CP platform.

Tools & Calculators
Geometry Calculator
Interactive tool showing how geometry changes across travel configurations (145–165mm), fork lengths (150–170mm), sizes (S/M/L), and RA headset positions.
Suspension Setup Guide
Factory-recommended air pressure, sag, and damping settings for 12 air shocks, 9 coil shocks, and 17 forks. Weight-based calculator with riding style adjustment.
Parts Compatibility Checker
Verify which components fit which frame before you buy. Covers shocks, forks, seatposts, brakes, drivetrain, and wheels across Paratu CP, Iuhu CP, and Paratu HL.
Riding Class Guide
Understand which travel configuration suits your riding style. Maps 4 travel settings to terrain types, rider profiles, and component recommendations.
