The P2 and Identiti both use ISCG-OLD mounts.

ISCG is also known as ISCG-03, or what we call ISCG-OLD. It is a mounting pattern for a chainguide, and very open to interpretation. This can sometimes lead to problems. ISCG-05 is a mounting STANDARD that was agreed upon by no less than five MTB companies at Interbike in 2004. It is stronger (by design, to withstand DH use), and much better defined to eliminate any mounting issues with ISCG-OLD.

Specialized, Giant, and Trek use ISCG-OLD on any model with ISCG tabs (with the exception of the 2007ish Trek Session 10, which used ISCG-05 and a special XW backplate for their elevated frame mounted roller).

Companies that use ISCG-05 in 2009:
Santa Cruz (Nomad/Bullit/V10/DriverCool
Iron Horse did since 05.
Evil
Norco
Kona
Lapierre
Yeti
Transition TR450 and newest model Covert
Intense - All 2009 and newer models. ISCG-05 bolt pattern but tabs misaligned from the drawings on 951.


The ISCG-OLD pattern can be made as strong or flimsy as the frame manufacturer wants. Where the tabs are integrated into the frame (such as the Demo and I believe Faith/Glory) you generally shouldn't have an issue. To cut costs, many other frame makers simply spot weld on a metal ring around the BB shell that aren't nearly as strong. Quality control also tends to miss when the ISCG tabs are not rotated correctly on the shell before welding. We've seen all sorts of crazy configurations before, even some from the big three mentioned above (mostly before 2005).

The general rule, if you don't know what ISCG pattern you have, is to simply measure the distance between the bolt holes. You can also use the drawings above to determine if your ISCG mounts are made to specification as well Cool

With ISCG-05 being a FREE standard to use it makes sense to switch over, at very least for the DH rigs.

Still ISCG-OLD. Rumor mill is maybe ISCG-05 in 2011. I've got my fingers crossed.

I'll just mention that I have the specs on my PB Album if anyone needs them...feel free to pass them around. The standards are free to use; no single company "owns" any of them.
