Buy cranks online – the right crankset for every riding style

The crankset is the central component of your drivetrain and influences power transmission, gearing and riding comfort in equal measure. Whether you are looking for a lightweight carbon crank for racing, a stiff aluminium crank for off-road use or a low-maintenance crank for everyday use: the selection ranges from proven series such as Shimano 105, Ultegra and Deore to SRAM Rival and GX Eagle, Campagnolo Record and special cranks from Rotor with oval chainrings. This means that as a road cyclist, mountain biker, gravel enthusiast or tour rider, you will find the crank that suits your riding style, your budget and your existing drivetrain.

Cranks by intended use

For road bikes, compact 2x cranks with 50/34 or 52/36 teeth are suitable, offering a balanced gear ratio for flat terrain and climbs. In the mountain bike sector, 1x cranks with chainrings between 30 and 34 teeth dominate, ensuring maximum ground clearance and chain retention. For gravel bikes, both 1x and 2x cranks with a wide gear range have proven themselves. In the trekking and touring bike sector, 3x cranks are still a popular choice when a particularly wide range of gears is required.

Crank technology: axle standards, bolt circle diameter & materials

When buying a new crank, several technical factors play a role. The axle standard (Shimano Hollowtech II, SRAM DUB, GXP, BB30 or PF30) must match the bottom bracket of your frame. The bolt circle diameter (BCD) determines which chainrings you can mount – common measurements are 110 mm for compact cranks and 130 mm for classic road cranks. In terms of material, you have the choice between lightweight carbon for ambitious riders and robust aluminium for everyday use. Also pay attention to the crank length, which is typically between 165 mm and 175 mm and should be matched to your leg length and your riding style.

Who is this category suitable for?

The category is aimed at road cyclists, mountain bikers, gravel fans, tour riders and commuters in Switzerland who are looking for a new crankset – whether as a replacement for a worn crank, as an upgrade for an existing drivetrain or as part of a complete new build. Workshops and mechanics will also find suitable cranks for different axle standards and frames here.

Quality, compatibility & installation

When buying a crank, it is worth paying attention not only to brand quality but also to compatibility with your bottom bracket, the correct bolt circle diameter and the right crank length. High-quality cranks from established manufacturers offer durable splines, precise chainring mounts and high stiffness for efficient power transmission. Many cranks can be installed yourself with standard tools – a torque wrench is expressly recommended.

Frequently asked questions

Which crank length is right for me?▾

The right crank length depends on your inseam, leg length and intended use. Common lengths range from 165 mm to 175 mm. A shorter crank can increase cadence and relieve hip angle, while a longer crank offers more leverage. Many riders choose crank length based on frame size and their personal riding style.

What is the difference between 1x, 2x and 3x cranks?▾

1x cranks have a single chainring and are especially popular on mountain bikes and gravel bikes – they require less maintenance, are lighter and simpler to operate. 2x cranks with two chainrings are the current standard on road bikes and offer a good gear range. 3x cranks with three chainrings are mainly found on trekking and touring bikes where a particularly wide gear range is required.

How do I determine the right bolt circle diameter for my chainring?▾

The bolt circle diameter (BCD or PCD) describes the circle on which the crank bolts sit. Common measurements are 110 mm (compact), 130 mm (classic) and 104 mm (MTB). You can measure it by measuring the distance between the centres of two adjacent bolt holes. When buying a new chainring, make sure that the BCD matches your crank.

Can I install a crank myself or do I need special tools?▾

Crank installation is quite doable yourself with the right tools. You usually need a set of hex keys, a torque wrench and, depending on the crank type, a crank puller or a special bottom bracket tool. When tightening, pay attention to the torque settings recommended by the manufacturer to avoid damage to the crank or the bottom bracket.

Which crank fits my bottom bracket?▾

The compatibility between crank and bottom bracket is determined by the axle standard. Common standards are Shimano Hollowtech II, SRAM DUB, GXP and BB30/PF30. Before buying, check the bottom bracket type of your frame and choose a crank that matches this standard or can be combined with a suitable bottom bracket.

What is the advantage of carbon cranks over aluminium?▾

Carbon cranks are lighter than aluminium and offer higher stiffness at a lower weight, which is particularly noticeable on road bikes and high-end mountain bikes. Aluminium cranks, on the other hand, are more resistant to impacts and scratches and are usually significantly lower in price. For everyday use and touring, aluminium cranks are often the more durable choice.

How often should I service my crank?▾

A regular visual inspection for cracks, corrosion and tight screws is recommended before each season. You should re-tighten the crank bolts approximately every 500 to 1000 kilometres with the specified torque. If there is play in the bottom bracket or cracking noises, a prompt check is advisable to avoid consequential damage to the crank and frame.

Which cranks are suitable for gravel bikes?▾

For gravel bikes, 1x and compact 2x cranks have proven to be particularly practical. 1x cranks with around 38 to 42 teeth offer a wide gear range and less susceptible technology on gravel and trails. 2x compact cranks with typically 46/30 or 48/31 teeth combined with a suitable cassette are ideal if you want to be flexible on both the road and off-road.
