A bicycle crankset, which is adapted to connect to a chain, includes a chainring, a spider, and a crankarm. The chainring has teeth on an edge thereof to engage the chain and a chainring axis through a center thereof. The spider has spider arms to detachably connect to the chainring and a connecting bore. The spider has a core axis through a center of the connecting bore, and the core axis is kept a predetermined distance away from the chainring axis to form a deviation. The crankarm has an engaging member to engage the connecting bore of the spider. Tips of the teeth of the chainring move in a noncircular path when the crankarm is exerted to drive the chainring to turned, and the noncircular path is adjustable by shifting a location of the connecting bore which change the deviation.
