130 mm BCD chainrings to fit standard cranks with 5 bolt, 130 mm spiders available in 38T, 40T, 42T and 44T.Does NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800. They WILL work with 11 speed chains. Strongly recommend a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.Note on mud: wide/narrow chainrings do no work well in heavy mud (Wolf Tooth or any other brand) if you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper and clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck.All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum.Crankset not included with chain ring!
