Crank Bolt Patterns.

Jordan300 · 06-16-2010, 12:27 PM

Do any of you have a printable bolt pattern sheet? I saw one at a shop in jacksonville a while ago and It should have asked where they got it. It had a bunch of dots on it and you could set your crank arm on the one master dot, and depending on where your other holes lined up it would dell you what size it was. Anybody have anything like this?

There's this one although it's missing the 56mm BCD. But that is obsolete now and no one makes that anymore.
Used to be TA and Suntour had that size for their granny rings.
