    Not without some work. I think there's a few companies with chromoly cranks for MTB out there. I know I have a set of them in my garage but I'm not sure if they are retail or not. OH - here's a listing of retail Kona Bulge DH cranks - there's two styles. Make sure you get a set of the Jack Sh!t Primo pedals with the 14mm axle (all the way to the end of the pedal) because if you need chromoly cranks, the next thing to break is going to be the pedal spindle and those'll cut up your calves real good.

    Profile makes a MTB DH set too - if your Haro's are really Profile you might be able to convert them.

    Yeah - follow the link at the bottom of my first post. Also type in profile mtb dh crank into a search engine and you find more - ALSO - I think Redline was doing some so check on their site too.

    The cranks will fit fine as long as the spindle is long enough and you have a euro bottom bracket.

    Plenty of street riders using BMX cranks.
