I bought a Salsa 135bcd Chainring once for my Athena cranks. It looked like nice quality, but it was too small to fit on the spider. I had to file down the surface where the chainring meets the spider to get it on. I probably should have sent it back, but I was impatient to get the bike up and running. Once I got it filed down, it worked fine, but I wound up replacing it with a Miche track chainring to match the rest of my 1/8" drive train. I also have a Miche track hub, cog/carrier, and seatpost. It's all good quality stuff. Nice finish, and durable.
