Wolf Tooth Chainring Bolts Set of 4 104x30t
Wolf Tooth says these bolts are the best on the market. They have a 5 mm hex socket and are 10 mm long so you can use a bash ring with your 30t chainring. The bolt length is laser engraved on the head to avoid confusion with shorter bolts. Simply better. These work great with Wolf Tooth or any other brand threaded M8 x 0.75 chainrings.
