DIRTE Paratu CP - Trail

Paratu CP - Trail

Carbon eMTB · Trail · Complete bike

Maxon-powered, trail-tuned. Lighter, livelier, all day.

The same Maxon-powered Concentric Pivot platform, set up shorter-travel for all-day trail riding — quicker handling and a lighter feel, with the same climb efficiency and descending composure.

Calm on the brakes. Quiet on the climb.

The kinematics behind the ride. Read the Dirt for the feel — tap Lab for the curves, the numbers and the engineering.

Descend

Brake late and hard into a steep, loose chute and the bike stays planted — no skipping, no pitching you over the bars. You hold your line, and your nerve.

Anti-rise is held near 49% at sag and trends lower toward bottom-out, so braking forces neither lock the rear solid nor jack it down under you. A mildly rearward axle path lets the rear wheel move up and back through square-edge hits instead of fighting them. The chassis keeps its attitude instead of pitching forward — more grip, more control on steep, loose terrain.

Anti-rise % across rear travel — sub-100% throughout.
What it governs
  • Anti-rise — how braking forces load the suspension. Kept sub-100% throughout so the rear never jacks down or locks solid under hard braking.
  • Axle path — the arc the rear wheel travels. Rearward early to absorb square-edge hits rather than hanging up on them.
  • Leverage curve — near-linear (~2% progression) so grip and support stay consistent through the stroke — easy to tune with air or coil.

Climb

Sit and grind and it just goes — power down without the bob, the rear end calm and efficient. Nothing is fighting the suspension on the way back up.

Anti-squat sits at 97.3% at sag in climbing gears — high enough to resist squat under power, yet the rear stays fully active over small bumps. That's the Concentric Pivot paradox: pedalling efficiency and small-bump traction at once, normally contradictory goals. Pedal kickback is held to 3.0–3.5°, so square hits don't yank the cranks back under your feet.

Anti-squat % across rear travel — high at sag, easing deeper in.
What it governs
  • Anti-squat — ~97% resists squat under power without locking the rear end, so it pedals firm but never dead.
  • Pedal kickback — 3.0–3.5° — low enough that impacts stay off your feet, even deep in the travel.
  • Concentric pivot — main pivot on the BB axis, horizontal shock, no idler: fewer parts, less friction and noise, predictable service.
