I have run into a bit of a dilema with my drivetrain set-up so any help would be appreciated. I am atempting to build a fr/dh bike and two of the pieces i have are a 02 DaBomb Mindbomb frame and a mrp lrp. The frame has a design similar to this http://www.dabombbike.com/htm/product/frames-projectile.htm# .My questions are:

1. How is it possible to run a dual ring system on this frame?

2. If i can't run a dual ring system is there any way to run a single ring system with the mrp lrp?

Thanks,
-Rygel

No shiftable dual ring, there is no routing for the cables.

thanks jay,

what about my second question?

I don't see why not. But, you won't get the same benefits as a normal guide system. Just make sure you rotate the roller as high up as you can get it on the iscg mounts. Also make sure you're getting a good chainline since that frame uses a 165mm hub.

The front derailleur acts as part of the LRP guide system. You're likely going to be dropping a lot of chains if you run it on that Mindbomb, sans front derailleur obviously.

You could give it a shot, but I'd be looking for a single-ring guide right now if I were you.

Edit: If your goal is seriously to run a dual-ring setup, there's a chance you could do it with an E13 DRS. You'd need to use an e-type front derailleur, remove it from its mounting flange, and bolt it to the guide backplate. Then you'd need to run a full-length cable housing to the front deraileur, ziptying it to the frame and using a hose clamp on the final ferrule to simulate a cable stop.

Not for the faint-of-heart. Nor particularly useful with that bike, IMHO. Also expensive.
