The One Ultra Integrated Handlebar: Stealth Fighter-Inspired Aero Design for Cyclists

The One Ultra Integrated Handlebar – Where Stealth Tech Meets Road Cycling

Engineered for invisible speed: 20% stiffer than PRO series, 380g weight, and Asian-optimized fit.

5 Game-Changing Innovations

1. Stealth Aircraft Aerodynamics

✅ Zero-Gap Integration

  • Seamless stem/bar junction eliminates drag-inducing gaps (CFD-verified 3.2% aero gain vs. standard bars)

  • Integrated computer mount & cable routing – no bolt-on accessories needed

✅ Droplet-Shaped Cross-Section

  • 12% lower CdA than round profiles at 40km/h (wind tunnel tested)

  • Matte black nano-coating reduces surface friction by 8%

Key Specs:

  • Reach: 73mm 

  • Drop: 120mm

  • Widths: 360-420mm (20mm increments)

  • Stem Length: 80-130mm

2. Rider-Fit Geometry

✅ Short Reach Design

  • 15% shorter than Euro-centric bars (73mm vs avg 85mm)

  • -7° stem angle reduces spacer stack height by 1.3cm

✅ Ergonomic Refinements

  • 1.3cm topside rise for relaxed hoods position

  • 1.5cm flare improves descending control

Fit Comparison:

Parameter The One Ultra Standard Bars  Benefit
Reach 73mm 85mm 14% more upright
Hoods Angle 7° inward Neutral Reduced wrist strain
Spacer Reduction 1.3cm N/A Cleaner cockpit look

3. T800 Carbon Construction

✅ EPS Latex Molding

  • 0.2mm surface tolerance vs 0.5mm in bladder molding

  • 380g total weight (420mm x 130mm size)

✅ 61N/m Stiffness

  • 20% stiffer than previous PRO model

  • Lab-tested to withstand 1500N frontal impacts

Material Science:

  • Toray T800 carbon fiber: 5.8GPa tensile strength

  • 3K/12K hybrid weave for optimal compliance

4. All-Black Aesthetic

✅ Minimalist Design Philosophy

  • Zero visible logos – laser-etched serials only

  • Universal matte finish matches 98% of frame colors

✅ Customization Ready

  • Compatible with Shimano/SRAM/AXS groupsets

  • Garmin/Wahoo mounts sold separately

 5. Pro-Grade Accessories

✅ Aero Out-Front Computer Mount

  • 36g CNC aluminum – 50% lighter than generic mounts

  • Integrated GoPro/light bracket

✅ Cable Management Kit

  • Silicone grommets for 1.5-5mm housing

  • Di2/EPS internal battery compatible

Technical Breakdown

Wind Tunnel Data:

Scenario Watts Saved vs Standard Bar
40km/h Solo 12W
45km/h Peloton 8W
35km/h Crosswind 5W
