Cycling Backpack & Messenger Bags

What size backpack is best for cycling?

Selecting the right volume depends on the duration of your trip and the specific items you need to transport safely. For a fast road training session where you only need a puncture kit and a gilet, a compact 5-10 litre pack is optimal to maintain aerodynamics and minimize sweat. If you are commuting to work, a 20-25 litre capacity in our cycling backups range offers enough space for a full change of clothes, shoes, and a lunch box. The reason for choosing a slim profile is to keep the weight centered along your spine, which maintains your balance on the bike. Expert advice: Overloading a bag can cause the straps to dig into your shoulders and restrict blood flow. Always utilize the external compression straps to keep the internal contents from rattling, which reduces the perceived weight and prevents the bag from deforming against your helmet when you are in a tucked riding position.

What are the benefits of using cycling messenger bags?

Messenger bags are a popular choice for riders who need frequent, rapid access to their belongings without removing the entire carrier. These single-strap bags are built to swing around to the front of the body, making them perfect for couriers or students. Our cycling messenger bags feature a cross-body stabilizer strap, also known as a "third-leg" strap, which keeps the bag firmly on your back while you are pedalling at high speeds. The technical reason behind the wide, padded shoulder strap is to distribute the weight across a larger surface area of the chest and shoulder, preventing localized pressure points. Small tip: Ensure the main buckle is positioned on your chest rather than your shoulder to avoid chafing. These bags often include high-visibility reflective strips and dedicated loops for clipping on rear lights, enhancing your safety when navigating through heavy traffic or low-light environments during your evening commute.

What features help with ventilation in cycling bags?

Heat management is a primary concern because a bag creates a barrier between your skin and the moving air, leading to a "sweaty back" effect. To combat this, look for bags equipped with a mesh-covered foam back panel or a suspended trampoline mesh system. These designs create a physical gap between the bag and your jersey, allowing air to circulate freely and evaporate perspiration. Cyclists planning longer commuts or touring rides often explore practical storage options like bike bags designed with ventilation-focused back panels and ergonomic support. The reason for using perforated EVA foam in the shoulder straps is to provide cushioning while allowing heat to escape through the holes. Additionally, choosing a bag with light-colored fabrics can help reflect sun rays during peak summer. Small advice: Loosen the straps slightly during low-intensity sections of your ride to increase airflow, then tighten them back up for technical descents where stability is paramount. Combining a ventilated bag with a technical cycling jersey ensures that moisture is moved away from your body as quickly as possible, keeping you dry and comfortable.
