This is the Wolf Tooth set of 4 chainring bolts with matching nuts for single ring (1x) setups, in black anodized aluminum.

What it's for

These short bolts and nuts attach one chainring to a crank spider. They are made for bolt on single rings that have plain through holes, where the bolt passes through the ring and spider and threads into a nut on the back. Standard double ring bolts are too long for one ring and will not clamp it tight.

Compatibility

• Fits: bolt on single chainrings without threaded standoffs, including Wolf Tooth Drop-Stop rings with through holes and other brands' single rings
• Does not fit: double or triple chainring setups. These are for 1x only.
• Does not fit: rings with built in threaded standoffs. Those take a bolt with no nut.
• How to check yours: Count the chainring bolts on your crank. This set covers 4 bolt cranks. Wolf Tooth sells a set of 5 for 5 bolt cranks.

Setup and installation

• Torque: 7 to 8 N·m
• Grease: light grease on the threads only
