Good posts so far, much appreciated. I've settled on the FX3 disc, which appears to have the best components I've seen amongst the major four manufacturers for its price point.
One last question; it has a 1x10 drivetrain - I'd think this would have several advantages such as less parts/possible front derailleur issues, lighter weight, simpler shifting, etc., as it has a wider gear range at 11-46t than most. That said, are there any disadvantages to having only a single gear up front instead of the more common two?
