I have a new road bike the came with an FSA MegaExo crank set, 50/39/32T, 130mm. Recently I noticed that about 1/3 of the teeth on the 50/30 rings have their tips broken off. The amount of broke off is a bout 1/4 - 1/3 of the tooth height. The bike has about 500 miles on it. The rest of the rings do not show much wear off, cogs (Shimano Ultegra) look good too. The chain, a Shimano 105 CN5600 looks fine as well.
Does this have to do with shifting gears while climbing/starting? Most of my riding is on flat roads and I do not do much hard starting. Has this happened to any of you? What could have caused such a quick wear off? Do I need to replace the rings now?
