i took off my front sprocket cover last night and noticed this 1/8 aluminum piece that was attached to the cover is this a stock item...? it doesnt look like it will fit with a 15t either... i took a pic to show what im talking about...sort of looks like a cheap case saver..? if it doesnt end fitting any suggestions on a case saver...i looked on ebay and didnt find anything...seems like a small investment to make to prevent alot of headache
