Wondering if you have any rear derailleur hangers in stock for the Co-op ADV 2.3 bike? If yes, is it possible to order it instead of coming into the store?
@Wub Thanks for reaching out!
Parts that specific to a bike are not available to order from REI outside of the bike shop in store. You could call your local REI Bike shop and inquire as to the part number (or email our bike techs at email@example.com) and see if you could track down the part on your own if you wanted. Depending on what the bike shop has ordered they may have the part you need in stock!
Hopefully this helps, thanks!
