Hello, Does anybody have experience with Profile BMX cranks. I am building up a new ss, and am considering running these cranks with a chainwheel, rather than a spider and chainring. The simplicity of this setup is tempting me. Also, chainline adjustment seems unlimited with this setup, where it seems more complicated with common mtb crank/bb setups(Race face, TruVativ). I have been reading some pretty negative reviews about Race Face and TruVativ bottom brackets as well. Any opinions appreciated.
