Bike Accessories

Bike accessories is the collective term for everything that makes your road bike, time-trial bike or triathlon bike functional, comfortable and race-ready, beyond the bike itself and your clothing. For cyclists, bike accessories revolve around power transfer, hydration and the right storage for repair materials. For triathletes it goes a step further: they optimise the bike for aero position, integrated nutrition systems and a fast change in the transition zone. The right accessory makes a measurable difference in comfort and performance on both fronts.

In this range you will find bike accessories for all parts of the bike and the cycling sport: from bottles, bottle cages and integrated hydration systems to triathlon handlebars that put you in an aerodynamic time-trial position, bike pedals, power meters, bike computers, indoor trainers for home use and bike cases for transport. Saddle bags, frame bags, bike saddles, bike pumps, bike lights and maintenance products are also here. Whether you are looking for a single specific upgrade or fully equipping your bike for a new season, everything is in one place.

What bike accessories are there?

The range is divided into subcategories by accessory type. Below is an overview of the five clusters to guide you quickly to the right category.

Hydration: bottles, bottle cages and hydration systems

Bottles and bottle cages are the most used bike accessories for cyclists and triathletes. A standard bottle cage mounts to the frame and holds a 500 or 750 ml bottle in place. For triathletes, saddle-mounted bottle cages are popular: these are fitted behind the saddle and accommodate one or two bottles without disrupting aerodynamics. Integrated hydration systems go a step further: they are mounted on the handlebar or in the fork and allow drinking in the time-trial position without taking your hands off the bars. Browse the full range in the bottles and bottle cages category.

Position and aero: triathlon handlebars

A triathlon handlebar, also called an aerobar or time-trial bar, is a handlebar extension that puts you in a low, aerodynamic position with your arms on the elbow pads. That position significantly reduces air resistance compared to a standard road handlebar and is the most effective way to go faster on the bike without producing extra power. Triathlon handlebars are available in versions for mounting on an existing handlebar and as a complete time-trial bar. Models vary in the degree of adjustability and the weight of the construction. Browse the overview in the triathlon handlebars category.

Power transfer and measurement: bike pedals and power meters

Bike pedals, together with shoes, determine how directly your leg power is converted into forward motion. Clipless pedals lock the shoe to the pedal for a stiff, direct connection and are standard for cyclists and triathletes who ride for performance. The 3-bolt road pedal and the 2-bolt MTB pedal are the two most commonly used systems. Browse the range in the bike pedals category. A power meter measures how many watts you actually produce and is the most direct training and racing tool for athletes who train by power: the measurement is independent of heart rate, speed or wind direction and gives real-time feedback on your effort.

Storage and transport: saddle bags, frame bags and bike cases

Saddle bags are mounted under the saddle and are the standard solution for carrying an inner tube, tyre levers and CO2 cartridges on the bike. Frame bags go in or on the frame and offer more capacity for longer rides and bike touring. For transporting the bike to a race, training camp or holiday destination, bike cases and bike bags offer the best protection. Hard bike cases withstand the demands of baggage handling; softer bike bags are lighter and easier to store at your destination.

Training, navigation, comfort and maintenance

Indoor trainers allow you to ride your own bike at home or in a warm-up tent regardless of outdoor conditions. Smart trainers connect to training apps and simulate resistance based on the course or a training programme. Bike computers and GPS devices record speed, distance, heart rate, power and navigation routes and are a standard tool for cyclists who want to analyse their training. Bike pumps, bike maintenance products and bike lights complete the range for athletes who also maintain their bike themselves and want to ride safely in any light.

Which bike accessories suit you?

The accessories you need depend on your discipline, how long you ride and what you want to improve or add to your equipment.

You are a triathlete and want to optimise the bike for racing: start with a triathlon handlebar for aero position, add an integrated hydration system for in-position nutrition and use saddle-mounted bottle cages for extra fluid capacity without aerodynamic loss. These are the three upgrades with the most impact on time-trial performance.

You ride long distances as a cyclist and want to be well equipped: get a reliable bottle cage and bottle on the frame, a small saddle bag with repair materials and a compact bike pump. These are the basic accessories that ensure you never stand by the roadside with a flat tyre.

You want to train more seriously and track your power: a power meter combined with a bike computer gives you the most accurate insight into your effort and training effect. Power is independent of wind, gradient and day-to-day variations in heart rate and is therefore the most reliable training tool for targeted improvement.

You are travelling with your bike to a race or training camp: a bike case protects your bike during flights and coach transport. Hard and soft cases are available for road and triathlon bikes, including options with built-in wheels for easy manoeuvring through airports.

You want to train at home and not depend on the weather: an indoor trainer connects to your own bike and allows targeted power training, warm-up and recovery rides indoors. Smart trainers connect to popular training apps for a realistic riding feel on virtual courses.

Frequently asked questions about bike accessories

What is a triathlon hydration system and how does it differ from a regular bottle?

A triathlon hydration system is an integrated hydration solution mounted on or in the handlebar that allows drinking while riding in the time-trial position on the aerobar. You do not need to take your hands off the bars. A regular bottle in a bottle cage on the frame requires you to sit up to drink, which works fine for road cyclists but is awkward for triathletes in the time-trial position. Some hydration systems are equipped with an indicator showing how much fluid remains, useful in races where precise dosing matters.

What is a saddle-mounted bottle cage and when do you use it?

A saddle-mounted bottle cage is a bracket system fitted behind the saddle that accommodates one or two bottles. The system is popular with triathletes because it provides extra fluid capacity without affecting aerodynamics at the front of the bike. Saddle-mounted bottle cages are available in single-bottle (compact) and twin-bottle (for longer distances) versions, sometimes combined with extra attachment points for nutrition pouches or gels. When choosing, check the maximum bottle diameter the system accepts and whether the bracket system is compatible with the seat post and saddle of your bike.

How do I choose a bike computer or GPS device?

A bike computer records speed, distance, cadence and heart rate; a GPS bike computer adds navigation, altitude profile and route tracking. For cyclists who want to navigate on unfamiliar routes, a GPS model is the logical choice. For triathletes, connectivity with a power meter and heart rate strap is important. When choosing, look at the ease of use of the interface, battery life during longer activities and whether the device supports connections to your training platform. Devices range from simple models for basic tracking to comprehensive multisport computers for triathletes and professional cyclists.

What is the difference between a hard and soft bike case?

A hard bike case offers the best protection for your bike during flights and baggage handling by airlines. The rigid shell keeps the contents intact in the event of drops and stacking of other luggage. A soft bike case or bag is lighter and easier to store at your destination, but offers less protection in rough handling. Soft bags are a good choice for transport by car or coach where you can keep an eye on things yourself. For flights most athletes choose a hard case or a well-padded soft case with internal shock absorbers.

Which bike pedals match my cycling shoes?

Bike pedals and shoes work together via a cleat system that clips the shoe to the pedal. For road bikes and triathlon bikes, the 3-bolt road pedal is the most commonly used system, with cleats protruding from the underside of the shoe. For mountain bike shoes and gravel bikes, the more compact 2-bolt system is used, with cleats recessed in the sole tread. Cleats are generally not included with the pedals and are brand-specific. If you already have shoes, check which cleat system the shoe uses before buying pedals: road pedals do not fit shoes with 2-bolt holes and vice versa.
