The Ultimate Guide to Custom Cycling Kits: Sizing, Fit & Comfort (2026 Edition)

Choosing the perfect custom cycling kit isn’t just about looking pro on the group ride—it’s about aerodynamics, endurance, and comfort. Whether you are attacking a climb or cruising on a Sunday coffee run, your apparel is your most important piece of equipment after your bike.

At Heini Sports, we combine Italian craftsmanship with Toronto-based innovation to deliver high-performance custom apparel with No Minimum Order Quantities (MOQ). But with so many options—Aero vs. Club fit, cargo bibs vs. standard—how do you choose?

This guide breaks down everything you need to know to build your perfect kit.

1. Choosing the Right Cycling Jersey: Aero, Club, or Relaxed?

One of the most common questions we get is: "How should a cycling jersey fit?" The answer depends on your riding style.

Aero / Race Fit (The "Second Skin")

Designed for speed. This fit minimizes wind drag and is tailored for lean, performance-focused cyclists.

• Best For: Racing, fast group rides, and time trials.

• Heini Recommendation: The Nizza Pro Jersey. It features raw-cut sleeves, a close-fitting cut, and uses a combination of three technical fabrics (Interpower + Interlock) for maximum breathability.

Club Fit (Performance Comfort)

A balance between aerodynamic efficiency and comfort. It’s form-fitting but not restrictive.

• Best For: Club rides, training, and long weekends.

• Heini Recommendation: The classic Nizza Jersey. It offers raglan sleeves for shoulder mobility and silicone cuffs to keep the jersey in place without squeezing.

Relaxed / Gravel Fit (Casual & Versatile)

Looser and more forgiving. Ideal for riders who prioritize comfort over aerodynamics or for mixed-terrain riding.

• Best For: Commuting, gravel adventure, and cafe stops.

• Heini Recommendation: The Merino Wool Jersey. Made from Scotland Merino, it offers natural moisture-wicking and temperature regulation with a relaxed urban style.

• Bib Shorts vs. Waist Shorts: Which is Better?

When designing custom team kits, the debate often lands on bibs versus shorts.

Why Choose Bib Shorts?

Bibs eliminate the waistband, removing pressure from your stomach and ensuring the chamois (pad) stays perfectly aligned with your saddle.

• For Gravel/Endurance: The Spider Bib Shorts are a game-changer. They feature cargo pockets for carrying snacks or phones—perfect for gravel rides where jersey pockets might be covered by a hydration pack.

• For Women: Bathroom breaks can be a hassle with bibs. That’s why we engineered the Stelvio Women’s Bibs with a unique Drop Tail design, allowing for easy breaks without removing your jersey.

Why Choose Waist Shorts?

Easier to put on and cooler in extremely hot indoor training environments.

• Heini Recommendation: Our Sports Fit Shorts allow for full customization and are great for running or gym work alongside cycling.

• The Chamois (Padding): The Heart of Your Ride

Not all pads are created equal. The right chamois prevents numbness and saddle sores. At Heini Sports, we use high-density Italian foams tailored to ride duration.

How to Choose Your Pad

• For 6+ Hour Rides (Ultra-Endurance): Look for the Marathon Grey Pad. It utilizes high-density foam (Density 90+60+40) to absorb severe vibrations, making it ideal for gran fondos and gravel grinding.

• For Racing & Tempo (4-6 Hours): The Performance Pad features a density of 80/120 with perforated fabric for rapid drying—perfect for high-intensity sweating.

• For Women: Anatomy matters. Our Yellow Pad or Evo Women Pad are specifically thermoformed to support the female ischial and perineal zones, ensuring stability and reducing pressure.

• Fabric Technology: Why Material Matters

Your custom sportswear should work as hard as you do. We use eco-friendly dye-sublimation (using soy-based inks) that produces zero water waste.

What to look for in 2025:

• Heat Management: Fabrics like Interpower and Mesh panels (found in our Miami Jersey) maximize ventilation on hot days.

• Cold Weather Protection: For winter riding, look for Superroubaix fabric found in our Spider Thermo Tights, which provides insulation without bulk.

• Aerodynamics: Our Butterfly Aero Suit uses specific textures to trip the air, reducing drag for triathletes and time trialists.

• Sizing & Fit Guide: Measure Twice, Order Once

Since custom cycling apparel is often made-to-order, getting the size right is critical.

Key Measuring Tips:

1. Chest: Measure under the armpits at the fullest part.

2. Waist: Measure at the narrowest part (not your hips).

3. Inseam: Critical for bib tights like the Spider Thermo.

Pro Tip: Cycling gear is meant to fit snugly to wick moisture. If you are unsure between two sizes, consider the fabric stretch. Our Diamond Bib Shorts use a 4-way stretch Lycra that adapts to muscle movement, offering a more forgiving fit. For detailed charts, visit our Size Guide.
