I’m Alberto Arenas — a passionate, experienced bikefitter dedicated to helping cyclists of all levels ride more comfortably, efficiently, and confidently. With over a decade in the bikefitting world, I’ve learned that every rider is unique — from your body, goals, and riding style to your experience with pain, performance limits, or just wanting to enjoy the ride more. My approach goes beyond simple measurements; I take time to understand your journey, your cycling history, your goals, and what matters most to you on and off the bike. My mission is to thoughtfully and precisely tailor your bike setup so that it fits you — whether you’re chasing your next personal record, training for a big event, or simply riding for the joy of it. Every bikefit is personal, detailed, and focused on helping you feel stronger, more comfortable, and truly connected to your bike.

Over a decade of experience in precision bikefitting, enhancing comfort, performance, and efficiency.

Aerodynamic Analysis

Using the AiRO software, we evaluate how positional changes influence aerodynamic drag and projected power savings


What We Measure

• Position-specific CdA estimation
• Relative watt savings at target speeds
• Pad stack & reach influence on drag
• Torso angle impact on frontal area
• Helmet comparison testing 

What you Learn

• Which posture produces the lowest estimated drag
• How sustainable that position is over race duration
• Estimated watt savings at race-specific speeds
• Trade-offs between aerodynamics and comfort

Testing Protocol

We test controlled variations of:

• Aerobar stack and reach
• Shoulder width and shrug
• Head position
• Helmet selection (optional comparison)

Each variation is evaluated to determine projected CdA differences and relative aerodynamic efficiency


Outcome

You leave with:

• Optimized aerodynamic position
• Estimated CdA value
• Projected watt savings at selected speeds
• Clear understanding of sustainable race posture

Elite
​Performance Lab

$450

Duration: ~4 hrs

Includes Performance Fit + Aero Performance Fit

+

Shimano Dynamics Lab 

Using the Shimano Dynamics Lab fitting jig, your current bike position is precisely replicated using X/Y laser calibration.

This allows controlled positional adjustments independent of equipment constraints.


3D Pedal Mechanics Analysis

Our 3D Pedaling Analyzer evaluates:

• Left/right balance
• Force application (Vectors)
• Pedal stroke symmetry
• Efficiency through 360° rotation
• Stability under load

Data-Driven Optimization

Based on pedaling analysis, we refine:

• Cleat alignment
• Stance width
• Saddle position
• Aerodynamic posture sustainability

Position adjustments are validated biomechanically and dynamically


Performance Report

You receive:

• Full pedaling stroke analysis
• Left/right balance metrics
• Efficiency breakdown
• Recommended positional refinements

Follow-Up Support

Includes follow-up review within 3 months to validate adaptation and performance progression.
