The FSA Pro / V3 Single chainring for mountain bikes is precisely cnc machined from 7075 / T6 aluminium. It is compatible with the popular 104 mm 4-arm BCD. Featuring a Megatooth profile (narrow-wide) it is especially suited for 1x10/11-speed drivetrains because it provide maximum chain retention.
Megatooth: The MegaTooth's teeth are longer than standard with an asymmetric profile shape, a diamond-shaped cross-section and a unique system of alternating thick then thin teeth. This allows for smooth chain engagement, meaning that the chain always remains in close contact with the chainring to give you the most reliable and positive drive possible.
Fitting for derailleur: 11-speed
Material: aluminium
