I've heard some bikes just can't run a SRAM XX front derailleurs (talked to LBS mechanic), and wondered if that is the case with the Zirkel. My drivetrain is full SRAM XX. During the build the dealer could not get a full range of shifting in the lower chainring, without chain/cage contact on the lower gears. (The contact is at the bottom part of the cage, not on the sides). I'm wondering if anyone else had this problem, or if you think the front derailleur should be able to clear the chain. I noticed a high clamp has a different cage than the low clamp when looking at photos, but haven't looked into whether that would work. Bottom line, I can shift down into the lower chain ring, but anything below the top 4-5 gears results in the chain resting on the cage....i.e. I currently only have SRAM XV (15 gears), and really want the full 20.
Stats (all 2011):
SRAM XX front, low clamp
Chainring 42/28 Combo

Do I need to try a different front derailleur (XTR 2x10?), or should this be a non issue? I wrote to email@example.com but have yet to receive a response. Thanks for any assistance.
