These chainrings are specially crafted for Surly OD cranks and also work well with other 5-bolt 94 BCD cranks. They feature the innovative, patent-pending Drop-Stop asymmetrical tooth design. This design offers long wear life, excellent mud clearance, and top-notch chain retention. They are great for 1x9, 1x10, 1x11, and 1x12 drivetrains. Compatible with most 10-, 11-, and 12-speed chains (except Shimano 12-speed). For Shimano 12-speed chains, use Wolf Tooth's specific chainrings. If you have a 9-speed drivetrain, a 10-speed chain gives a better fit. Made from durable 7075 Aluminum. It's advisable to use a clutch-style rear derailleur. The chainring is black and made of aluminum.

Using this chainring is quite straightforward. First, check if your crank is a 5 - bolt 94 BCD type. If it is, you can install the chainring on it. For drivetrains, it works well with 1x9, 1x10, 1x11, and 1x12 setups. Just make sure to use the right chain. Remember, Shimano 12 - speed chains need a specific chainring from Wolf Tooth. If you have a 9 - speed drivetrain, use a 10 - speed chain for a better fit. As for maintenance, keep it clean from mud and dirt. You can use a soft brush and some mild cleaner to wipe it down. Since it's made of 7075 Aluminum, it's durable but still needs regular checks for any signs of wear. Also, it's recommended to use a clutch - style rear derailleur to enhance the performance and chain retention.
