KNOW BEFORE YOU COMMIT TO BUY: Read the ENTIRE DESCRIPTION. Look at ALL THE PICS. RESEARCH compatibility prior to purchase. Thank you! Hello and thanks for checking out this listing of a new set of SRAM Force AXS 46/33-tooth chainrings for your compatible crank! I discovered a large hoard of these rings in the back stock of a high-end bicycle manufacturer during a model year change. Each will come to you in the new-without-retail-packaging condition seen in the included photographs. For use with SRAM's proprietary 4-arm 107mm BCD spiders or Quarq power meters. 46/33t combination is perfect for gravel & road riding on rolling and even very hilly terrain. NO additional parts such as spiders or mounting mounting bolts are included with this listing. Please see the included pics of the actual item you will receive. Enjoy FREE SHIPPING within the USA! Please contact me with questions, I will do my best to answer them. Review my feedback and buy with confidence. Thanks again! Don't forget to follow me on Instagram at "thehouseofcogs"!
