This is from a Merida Reacto 4000 complete bike that I purchased new. I used it for about a year and then replaced it with a different manufacturer's BB, so I'm selling this. It has scratches and minor imperfections from use. Please check the photos for the condition of the chainrings. I believe the condition is relatively good. To avoid any problems, please look at the photos and make sure you are satisfied before purchasing. Thank you. Road bike Cross bike Mountain bike
