To be honest, I was looking for a chain ring with BCD 151 mm, but by mistake I clicked on an Ebay item with BCD 144 mm. No problem, since most of my cranks and rings are 144 mm and I didn't have a 49T yet, so this is a welcome addition to my range of track chain rings.
Same as this chain ring (which IS 151 mm though), it is the "Record" type, which is good and nice.
It's not completely new, but it has just minimal wear signs. So, decades of life in it.
