When to replace chainrings?
Discussion
I noticed when cleaning my bike last night and the chain rings are starting to look a bit worn. Not fully rounded, but definitely worn.
At what point do they need replacing? The bike sometimes struggles to shift to the big ring, but I haven't tried adjusting the cables/mech and they haven't been done for a long time.
Also, with rings, do I need to go for the same as are currently fitted (XT chainset with original XT rings) or will others fit?

Other rings should fit if you are thinking of upgrading (XTR?), but maybe your LBS could check compatibility first if you are unsure?
Are chainrings speed specific? I think they might be, so check to make sure you order a 9-speed, 10-speed chainring as appropriate for your bike.
When you start thinking about replacing chainrings (excessive wear will leave them looking 'hooked' - kind of like a shark's fin shape. Do not confuse some teeth that look like the tips have broken off with being due to damage or wear - some are shaped like this to aid shifting, but then again if loads are missing in one area, this will be due to damage caused by rocks/logs etc!), then you should also look at the rest of the drivechain at the same time.
When was the rear cassett changed?
Is the chain worn?
There is no point fitting nice new chainrings, only for the old manky, streched chain to be re-fitted. This will cause the new chainrings to wear prematurely.
Likewise for the rear cassette. Don't fit new chainrings and chain while leaving a manky old cassette fitted.
