Salsa chainrings are made from CNC-machined 7000-series aluminum for low weight and excellent stiffness. The teeth are neither ramped nor pinned so they're great for singlespeed use. They also work with double and triple ring setups, too.
To choose the correct chainring, 1) determine the number of teeth (they're usually marked, or simply count them), 2) determine how many bolt holes there are (usually 4 or 5), and 3) determine the Bolt Circle Diameter (BCD; see diagram).
Common BCDs include:
130mm (Shimano Road)
135mm (Campagnolo Road)
110mm (Compact Road)
104mm, 94mm, and 64mm (Mountain)
Finding the number of teeth and bolts holes is easy. If you don't know your chainring's BCD, measuring it is tricky. So, instead, measure the exact distance (center to center) between 2 adjacent bolt holes. Then find that number on the correct chart below to determine the BCD for your chainring.

|Bolt to Bolt (measure center to center)||Bolt Circle Diameter (BCD)|

This chainring has a 5-bolt pattern and is for use with 8, 9, and 10-speed Shimano/SRAM cranksets.
Size 22T is for inner ring use; sizes 32-34T are for middle ring use; 42-44T are for outer ring use.
