Chainring Tech Tip
How to measure your chainring bolt pattern
The 2 most common bolt patterns are:
110 Bolt Pattern = 65mm center to center (actually 64.7mm)
130 Bolt Pattern = 77mm center to center (actually 76.4mm)
Most common on tandems in the last 10 years (in particular FSA) 130-74 5 Bolt Pattern.
Coming soon 110 Bolt Pattern for tandem doubles. When ordering make sure you look at our handy measuring procedure above.
