Truvativ Holzfeller OCT 1.1 vs 2.2 Difference?

[Brendan.]

As the title states, whats the difference between the 1.1 and 2.2?

I know that the 2.2 is intended to be used with 2 chainrings and and 1.1 with 1 chainring.

But is the spider identical or different? I can't seem to find a picture of the back of oct 1.1's

the 2.2's have 8 bolt holes, 104/64mm. Do the 1.1 have the same or just 4 holes 104mm?

The reason i ask is because i need new crank arms and i can get oct 2.2 crank arms cheaper than the 1.1's.

Will be used on a DH bike. already have 32t ring, bash gaurd, howitzer bb and e13 guide

Pretty sure the 1.1 don't have granny gear tabs (ie- only 4 holes). These tend to work a bit better as the granny tabs can foul on your chain guide, but if you're never going to need a granny gear and the tabs foul on the guide, just grind them off.
