Road Double X-Glide, 5-arm, 110 mm BCD Chainring

Specifications: Application: Road Attachment: 110 mm bolt circle diameter, 5-arm Teeth: 50 Gearing: 1x10-, 1x11-speed Technical Information: Material: aluminium (7075-T6) Technology: X-Glide™ SRAM's crank engineers have thrown the old standards overboard and developed a completely new chainring geometry. They have precisely matched the chainrings of different sizes and reworked the places where the chain and chainring meet. By adjusting the teeth of the chainring to the chain link pins (instead of to the middle of the chainring) you get twice as many shifting possibilities.
