My GRX equipped bike didn't come with these immobilizer wedges. From all of the other issues with the bike I should be thankful that it came with the caliper spacers. Do you have a Shimano part number or photo for these wedges? I am wondering if I can find some at my local LBS.
Another interesting question... Is the brake system likely to get air in it when the bars and the bike are turned every which way during transport?
