About two years ago, I ordered two 20t cogs and one 33t chainring. I received two chainrings and one cog. I was not able to achieve a swap with HBC so I have been sitting on my 33t chainring ever since. I noticed a lot of other folks have received orders that were not what they wanted so I thought that maybe an HBC swap page may help some of us get what we wanted!
I have a never used red 33t 5 hole 94BCD chainring. I would like to trade for a 20t cog or a 17t cog, preferably in black but anything will do!
