Need Help With New Parts

I have a 2001-2002 Ellsworth Joker. At the moment I have it set up with an ISIS bottom bracket and Race Face northshore DH cranks. I have a dual ring up front. The big ring is 32 and the smaller ring is smaller. I don’t have the bike on me.

With the current setup I would like to simply put on a good quality chain guide that is compatible with all of the above. I found a nice one from Race Face called the Atlas. Problem with this one is that it is designed to be used with the X-type bottom bracket. If I change my bottom bracket then I need to change my cranks.

Is there a really nice option out there that allows me to leave well enough along and get what I want (dual ring chain guide)? Any help would be appreciated.

Thanks,
John

Thank you for the quick advice. I checked out the website and the DRS is their dual chain model, but it is only available in a 4 bolt pattern. My northshore cranks have a 5 bolt pattern.

Also not sure what an ISCG tab is. I love biking, but am just getting into maintaining my own bike.
