32 Wheel Concept

R&D Programme — Not a Current Product

32" Wheel Concept

What happens to geometry, handling, and trail when you run a 32" front wheel on a Paratu CP or Iuhu CP.

The Concept

Why 32"?

A 32" wheel rolls over obstacles that a 29" wheel climbs, deflects on. The radius difference is 30mm — enough to measurably change how the front end tracks through rock gardens and root sections at speed.

The geometry effect is equally significant. A longer fork axle-to-crown (required by the larger wheel) combined with the increased wheel radius drops head tube angle by 1.5°–2.5° versus a standard 29" setup at the same fork travel — without any chip adjustment. That's a different category of geometry.

Both the Paratu CP and Iuhu CP accommodate a 32" front wheel without structural modification. The flip chip system still functions normally across all 5 positions.

⬡

More rollover

30mm more radius over a 29" wheel. Smaller obstacles stop registering at the bars.

⟵

Dramatically slacker

HTA drops into 60°–62° territory — beyond what any chip or fork swap achieves on a standard wheel.

◎

High trail, planted feel

Trail values reach DH territory. Front end stability at speed increases substantially.

✓

Frame already supports it

No modification. Flip chip still works. All 5 geometry positions still valid — just recalibrated.

R&D Configurations

Two Concepts

Geometry values below are R&D estimates computed from confirmed frame constants (R₂₉ = 378mm, R₃₂ = 408mm, base HTA 63.9° at 561mm A-C). Fork A-C values reference the KS 32" fork prototype — not a production product.

Most accessible entry point — rear 29" wheel means existing cassettes, brakes, and tires work as-is. The most likely first production config if this programme moves forward.

Mega Mullet

32" front · 27.5" rear

Extreme

HTA range (600mm A-C) 60.3°–61.0°

vs. standard 29+29 −2.9°–3.6° slacker

Trail (44mm offset) 177–183mm

Rear wheel 27.5" — Mullet setup

Character DH territory

Rear 27.5" lowers BB and quickens rear pivot feel while the 32" front dominates. Trail at 177–183mm approaches dedicated DH bike territory. For riders who want the absolute furthest from standard geometry the frame allows.

R&D disclaimer: All geometry values on this page are computed estimates based on confirmed frame constants and extrapolated fork A-C lengths. They are not measured from a prototype and have not been ridden. HTA values use rate −0.02353°/mm A-C, calibrated from EC2/EC3/PD02 CAD (2026-09-02). No 32" fork is currently in production for MTB use. Availability of this configuration depends on fork market development.
