Hi,
The only chainring I have that has a "shiny silver" finish in 44 or 46T is a used Specialites TA Zephyr 46T. It was fitted to a crankset on a bike I broke for some parts so I cannot be certain of the amount of use or mileage covered. The finish of the ring is still in very good order although it does have a few marks that would be expected for a used chainring. It is missing the pin that prevents the chain from dropping down the back of the crankarm.
As I do not know much about the ring and exactly how much life is left in it how does £5 posted sound?
Cheers
Jules
