So I have a Shimano Hone 3 ring crankset and a sram X.7 front derailleur with X.4 shifters. My current setup is 22-32-44t (stock), but I want to add a bashguard. After considering other options, and because I do a lot of XC/commuter stuff where I never get off the 44t ring, I figured I would drop the 22t to make the setup work.
Of course, for more comfortable shifting, I would not want a 22T drop for my only front shifting option... so I'm looking into getting the biggest 64mm BCD 4 bolt chainring I can find. I have seen 30t versions, but not good ones and they're overpriced, but I can get a Shimano SLX 26t which may be enough.

Anyways, is there somewhere where I can get a 28-30t inner chainring to keep more of the ratios I have now on my top two gears? Also, when I install the bashguard and have 2 rings to choose from, what is the best way to set up the shifters? I was thinking pushing the upper limit screw to hold it on the second ring would be best, but I haven't tried it before. Also is there a 2 ring shifter option or something I can change in the shifter to disable one of the speeds?
Thanks
