Had this for a year now, so i figure i should write a review. I am running this on a 68bb with the mounting plate on a TruVativ howitzer bb, it is an an iscg-old. I am running a SRAM X-9 short cage, 9spd. First things first, installing it was a b*tch. It really was. I ended up doing some pretty nifty bb spacer combos (from two bbs) and filing the top guide to get it to fit properly. After that tho
