Hey guys, just wondering if this has happened to any of you or maybe shine some wisdom.
Right after I swapped the front sprocket to a 14 tooth I noticed the lubes on the chain is uneven, like the sprocket is offset, yet again the chain runs straight on both sprockets.
If you look you can see the lube has worn out on the left side of the rollers more than on the right side like it shouldn't.
Maybe it's nothing but it's a colossal pain in the ass swapping it back to 15 and rather not if I don't have to.
Thanks

Front sprocket got mounted backwards... take it off and flip it around.

Bolt is to the right in this pic, sprocket should mount AWAY from the bolt:

The sprocket went in the same way the 15 came out, if I was to flip it the chain wouldn't last a minute before flying off
