Skin Deep: Solving Chafing and Irritation on the Bike

19 Dec 2025

Overcoming the Discomfort of Chafing

It is the silent ride-killer. You start the day feeling great, but as the kilometers tick over and the temperature climbs, you start to feel that familiar, localized sting. Chafing and skin irritation are incredibly common cycling problems, particularly in the humid Australian climate, but they are not an inevitable part of the sport.

At Caffeine and Cranks, we have engineered our technical apparel specifically to eliminate the causes of friction and irritation. Finding the right solution involves understanding two key technical elements: moisture management and seam construction.

The Cause: Salt, Moisture, and Friction

Most on-bike skin irritation is caused by a "perfect storm" of factors. When you sweat, your skin becomes softer and more fragile. As that sweat evaporates, it leaves behind abrasive salt crystals. Combine this with the thousands of repetitive movements involved in pedaling, and any rough surface or high-friction area on your kit will quickly lead to raw and painful skin.

This is especially true during those long, humid summer rides around Sydney or the mid-day heat in Queensland. If your kit holds onto moisture instead of moving it away, the friction is dramatically increased.

The Solution: Technical Moisture Wicking

The first line of defense against chafing is keeping your skin dry. We spend a significant amount of our design time sourcing and testing technical fabrics that move moisture away from the skin at high speeds.

Our Core jerseys and Pinnacle jerseys use advanced multi-filament polyester blends. Unlike basic cotton or standard activewear, these fabrics actively pull sweat into the outer layer of the jersey where it can evaporate quickly. By keeping your skin drier, we significantly reduce the softening effect of sweat and the resulting friction.

The Solution: Flatlock Seam Construction

Standard seams on many sports garments have a raised ridge on the inside of the fabric. During a three-hour ride, these ridges can act like sandpaper against your skin. This is why we use flatlock seam construction across our entire range of technical apparel.

Seamless Integration

Flatlock stitching creates a completely flat profile on both the inside and outside of the garment. It eliminates the bulky ridges that typically lead to chafing, particularly in high-movement areas like the inner thigh and underarms. This construction method is featured in our Men's Core Bib Shorts and Women's Core Bib Shorts, providing a smooth interior that protects your skin.

Laser-Cut Efficiency

In our Pinnacle series, we take this further with laser-cut hems and seamless openings. By removing the need for a sewn hem entirely, we eliminate another potential source of irritation, creating a smooth, non-restrictive transition from your gear to your skin.

Three Tips for Chafing-Free Riding

1. Use a Quality Chamois Cream

While technically built bibs are the first step, a quality cream provides an extra layer of protection on long rides, acting as a lubricant between skin and fabric.

2. Choose Your Sizing Carefully

Apparel that is too loose will move against your skin, creating more friction. Ensure your kit fits like a second skin to minimize movement. You can find your perfect size using our Size Guide.

3. Review Your Layering

Sometimes chafing is caused by a base layer with rough seams underneath a high-quality jersey. Ensure every layer in contact with your skin is technical, such as our Core Baselayers.

Focus on the Performance, Not the Irritation

Cycling is about the freedom of the road and the challenge of the climb. You should not be distracted by the discomfort of preventable skin irritation. By choosing gear designed with technical fabrics and flatlock construction, you are giving yourself the best possible chance of clear, healthy skin on every ride.
