130 BCD marking on SRAM crank

[SL7]

hi Hubbers,

 

Some help would be appreciated.

 

What does the marking 130BCD on a SRAM crank mean? See pic below:

Bolt circle diameter. Distance between the crank bolts c-c.

Thanks MD. Thats useful info if you want to replace the chainrings with another make.

130mm is the standard BCD, meaning most other chainrings will fit (except crampag) 110mm is the Compact BCD normally has chainrings with 50 and 34 teeth...

And just for the guys worried about getting a compact crank, there are standard 53/39 chainrings available with a 110BCD.  So you can convert your compact to standard if you want to!
