The double cup holder can come with no reducer or you can add one for an additional $5. I don't have it set up on my website to add two inserts. If you want a second one just send me a message and we can figure it out.Ok, quick question...I bought my rig with your dual cupholders already in it. However I noticed that there was only one extra small spacer thing (like coke can fit size). Is this all that comes with them or am I missing one?
