More Information
Summary:A bicycle derailleur pulley comprises a bearing region rotatable about an axis of rotation, a tooth region with teeth formed thereon for engaging into the chain, and a supporting structure that connects the bearing region and the tooth region. On at least one tooth of the chain-guiding pulley, on each of the inboard-side and outboard-side side surfaces thereof, there are formed guide regions for lateral guidance of the chain substantially parallel to the axis of rotation. At least one inboard-side guide region of the at least one tooth has an at least regionally reduced thickness dimension, relative to a central plane of the chain-guiding pulley, in relation to at least one outboard-side guide region, such that a chain section running substantially tangentially off the chain-guiding pulley can assume a greater skew angle in an outboard direction than in an inboard direction.
