From solid aluminium to your frame.
Every Hiisi is built to order. We group confirmed orders into production batches, then machine and assemble each frame to its rider's specification in Jyväskylä.
Cut to ±0.05 mm.
Around 24 hours of CNC machining turns 100 kg of solid aluminium into a 3 934 g frame. The pivot locations match the CAD model within ±0.05 mm. That keeps the linkage aligned when the frame is assembled. For scale, ±0.05 mm is thinner than a human hair.
Aerospace adhesive. Seven-stage process.
Structural adhesive bonding is the standard joining method in aerospace and Formula 1. It spreads load across the whole joint instead of concentrating it, and leaves no heat-affected zone. The seam between the two machined halves is invisible to the naked eye.
E-coated in-house. No paint.
Three e-coat finishes: Raw Silver, True Gold, Hero Bronze. Each one goes on our own line. The e-coat seals every surface, inside the cavities too, against corrosion.
Made for one rider. Yours.
Every frame is machined to a single person's measurements.
