How does the little allen bolt look like? I am not sure but i think it one of those self exstracting bolts.

Pic of crank in question?

 

Have you tried the SRAM website? They have detailed technical docs.

e.g.

http://www.sram.com/en/service/truvativ/view.php?catID=1&subcatID=5

If there is another bolt behind "allen-key screw cap" which can be seen through the "cap", then it is of the self extracting type

If so, replace the "allen-key screw cap" and then undo the inner most allen screw. This will pull the crank off as you unscrew it.

After removing the allen key nut, the crank needs to be pulled off.

 

You need a tools (available from any LBS) such as:

You could also try to force it off using some  "boer maak 'n plan" approach...

yup crank puller needed it....also in CT, can also use mine if needed.

[Overlord]

I was willing to remove the crank.

[mountain_lion]

Oh, sounds like it is a standard crank if a crank puller will remove it.

Richard, I doubt Overlord will read this. I see you are new here. This thread is from 2009.
