Now ther is a real problem in front of me - I need to chose the best option!
I thought about XTR chainrings, because they match all my requests - they are durable, they have a big rings too, titanium platting, perfect ramps and even nice look, but there is a problem with standarts (4 bolt spider has unique bolt patern) and it is hard to get ones.
Last year I bought one of the litest chainrings (US made), they were in perfect sizes (28/36/46) and were enough lite, but they were made of same cheap Aluminium and therefor they broke.
Which ones you can sugest for me - light and with good shifting performance?

Light weight everything!

Try TAs. All sizes you could want, ramped, pinned and in a couple of different colours.

If you really want chainrings that will last, look at Action tec.
be warned, cheap they are not!
