Bike cranks and chainrings

When choosing cranks, the size and type of bottom bracket is important. There are variants with 1 to 3 converters to pick from. For a functioning shift, you must also have a correctly selected derailleur and shift lever. The length of the cranks is selected according to the rider's height, the exact size will be revealed by the Bikefitting seat measurement. Most often, cranks are made of aluminum, the lightest ones are made of carbon. Single converters, tensioners or rock rings can be purchased separately.

Here is a short description of the features that are good to consider when choosing cranks:

Material:
- Aluminium: Light and durable material, commonly used in middle classes of cranks.
- Carbon Fibre: Offers an excellent balance between very low weight and good stiffness, often found in higher class cranks.
- Steel: Durable but heavy, usually used for basic and cheap cranks
Length: Common lengths range from 165 mm to 180 mm. Shorter cranks can provide a faster cadence, while longer cranks can offer more leverage.
Bottom bracket compatibility: Cranksets must conform to the BB standard.
Gears: Cranks can have one, two, or even three gears. The number of teeth of the converter determines the gear ratio. Choose a system that matches your drive and preferences
Q-Factor: The Q-Factor is the lateral distance between the pedals, which is given by the deflection of the crank. It affects the posture of the rider on the bike. A narrow Q-factor can reduce the load on the knees, but can impact stability.
