I have a stock 05 Specialized Bighit SPEC. It came with a single 38t chainring up front and a Truvative Boxguide. I would like to use it for FR in addition to DH. I want 2 chainrings and a bash ring/guard up front with a chain guide so I can pedal it. I bought a Truvative Hussefelt Double with P.C. Bashguard, but it didn't fit because it hit the ISCG frame tab screws. Has anyone successfully setup an 05 Bighit SPEC with 2 rings up front? Am I limited to 1 ring because of the ISCG frame tabs? Here are 05 Specialized Bighit SPEC specifications: http://www.specialized.com/bc/SBCBkModel.jsp?minisite=10080&spid=9400&bikeTab=techspec Here is what the bike looks like The best reply to this post would be someone telling me exactly what crankset, bash ring/guard, chain guide, and front derailleur would work, but any help is appreciated.
