Collection: Mix bike

When it comes to cycling and triathlon, there are two things you never want to go without: air in your tires and reliable equipment. A flat tire or low tire pressure can be the difference between a good and a disastrous training ride – or a missed PR in competition. That’s why it’s important to have CO2 cartridges and bike pumps that work when it matters.

At Transition Zone we carry equipment from Mixbike, which combines high functionality with user-friendly design. Whether you ride road, gravel, triathlon or exercise, we have the pump and air solution you need - for training, competition and repairs on the go.

CO2 cartridges are a triathlete's and cyclist's best friend when things go wrong. They take up minimal space, weigh next to nothing, and inflate your tires in seconds. In competition, they're the fastest and most efficient way to get going after a puncture.

Mixbike offers compatible CO2 cartridges that fit most inflator heads. They are precision-manufactured and filled with compressed carbon dioxide under high pressure. When the cartridge is activated, the gas is quickly released and fills the tube or tire without the need for manual pumping.

Advantages of CO2 cartridges from Mixbike:

Compact and lightweight – perfect for a saddlebag or back pocket

Lightning-fast inflation – ideal for competition

Uniform and controlled release of gas

Available in several sizes (typically 16g and 25g), depending on tire size

Always remember to combine with an inflator head that fits both Presta and Schrader valves. If you have carbon rims, you should consider using an insulating cover as the cartridges get extremely cold when in use.

While CO2 cartridges are perfect for emergencies, every serious cyclist should also have a classic foot pump at home or in the car. Here, Mixbike excels with its robust and user-friendly pumps that combine durability with precise pressure measurement.

Mixbike foot pumps are built from solid materials and designed to deliver high pressure with minimal effort. They have wide bases for good stability, ergonomic handles and clear manometers (pressure gauges) that make it easy to hit the precise tire pressure - important for both performance and comfort.

Features of Mixbike foot pumps:

Compatible with both Presta and Schrader valves

Easy reading of pressure in bar/psi

High volume and pressure capacity (up to 11 bar / 160 psi)

Stable and durable for daily use

A good pump doesn't just save you time – it ensures that you always ride with the correct pressure, which reduces the risk of punctures, improves rolling resistance and gives better control of the bike.

At Transition Zone, we are cyclists and triathletes ourselves, and we know what works. We only sell equipment we would use ourselves – and Mixbike is no exception.

We offer fast delivery, personal advice and a carefully curated selection that covers both training needs and competition days. So whether you need air before, during or after your ride, we have the solution ready.
