Thanks, our house is 4 years old and we are there every couple of months. I have had alot of riding time up there. I'm happy with the grouping I have just wondered about I guess the BB and internal parts more than chainring itself. That component is from my original 05 so its 6 years old. I am thinking an in depth once over by my LBS will do the trick. Maybe I can just get away with new bearings for now.
