Mountain bike chainring, Stronglight for Shimano 10x2-speed cranksets, 104-tooth bolt pattern, 4-arm symmetrical design, 40 teeth, designed for use as a large chainring, colour: black
Stronglight chainrings are CNC-machined from high-quality 7075-T6 aluminium. Equipped with shift guides, these chainrings are an equivalent and cost-effective replacement for the original SRAM chainrings.
The bolt circle diameter is 64 mm or 104 mm, for Shimano 10x2-speed cranksets. The 104 mm bolt circle is the standard MTB bolt circle. The 104 mm bolt circle is the most common bolt circle for 9- and 10-speed MTB cranksets. The distance between the chainring bolts is 104 mm, measured diagonally from centre to centre.
