Mountain bike chainring, Stronglight for Sram 10x2-speed cranksets, 104-tooth bolt pattern with thread, 4-arm symmetrical, threaded mount, 40 teeth, fits as a large chainring, colour: black
The large chainrings for the Sram 10x2-speed cranksets have threads in the large chainring. These are screwed in from the inside of the crank.
The Stronglight chainrings are CNC-machined from high-quality 7075-T6 aluminium. Equipped with shift aids, these chainrings are an equivalent and cost-effective replacement for the original SRAM chainrings.
The bolt pattern is 64 mm or 104 mm, for Shimano and SRAM 9/10/11-speed drivetrains. The 104 mm bolt pattern is the standard MTB bolt pattern. The distance between the chainring bolts is 104 mm, measured diagonally from centre to centre.
