The replacement market is very limited to find chainrings that are ramped and pinned especially for 110 BCD. I think Dimension used to make chainrings for Salsa, but now these carry the Dimension name with the same quality product.
I replaced the outer ring on my tandem triple, since I ran it too long with a worn chain. The shifting (which is more frequent on a tandem) is now smooth as silk again!
Nice outer for compact double or triple with good quality, lightweight and perfect for what I needed.
The finish is not up to the same standards as Dura Ace, but perfectly decent as far as exterior cosmetics and would be a good match for the native FSA rings.
