Cracked EAI cog, how did it even happen?
Hey everyone, I had just swapped my cog and when I finally checked it for the first time since last April (didn't really re-grease it since I knew it already had a good amount of grease between the treads). And well, when I took a closer look I saw a crack. How exactly does the cog crack? Use over time? Durability issues with EAI cogs?
Luckily I switched it out sooner than later, another crack was starting to develop, but had not gone the whole way yet. There were plenty of chips as you can see in the picture...
Anybody had this issue before?
