tandwielsets

A tandwielset is a bicycle gear set used to determine the available gear ratios by combining front chainrings and rear sprockets with the chain, enabling the rider to choose different mechanical advantages. It typically includes the crankset with one or more front chainrings and a rear cassette (or sprockets) mounted on the rear hub, connected by a chain and operated through derailleurs or other shifting mechanisms.

Front configurations range from single to triple chainrings, with 1x, 2x, or 3x setups common on road,

Compatibility depends on several standards: the crankset must fit the bottom bracket and provide the correct

Maintenance considerations include regular inspection of chain wear, cassette wear, and derailleur alignment, as well as
