I know, I know, it's just chainrings. However, these things are sweet! They are made by Boone Rings. They are custom titanium rings, I went with a 20t granny ring and a 31t middle ring. By going this route I be saving weight on the chain rings (20t ring weighs 13 grams, 31t ring weighs 35 grams). I will also be saving weight because I will be able to go with a 12-27 cassette which will save me an additional 50 grams over a 11-34 cassette. If the weight savings wasn't enough of a reason to go with the Boone rings the fact that they will refinish them every year was definately enough to convince me. Basicly I will be riding new chainrings every year for free after the first year.
Anyway, here is a picture of one of there chainrings (swiped picture from Strong Ti at mtbr), did I mention that these things are SWEET?!?!?!
Here is their warranty, how could it get any better than this?
