yer, this freewheel is a beast so-far as was said my run-ups have to be altered, but that only took about 5 secs to get used to... tis quick pickup and seems very sturdy and well made and jake, i had no trouble whatsoever putting the thing on it went on just as easy as the ENO i used to run, slid right on just gotta see if it takes the 'Will' abuse
