    Dura Ace 7850-SL wheel freehub body removal

    Shimano sent me a warranty replace freehub body for my Dura Ace 7850-SL wheels. These particular freehubs have a problem with an occasional load "clunking" sound when they engage. Apparently, Shimano acknowledges the problem and sends replacement freehub bodies direct to consumers.

    Anyway, how do I install them? Thanks in advance for any tips.

    The rate at which a wheel slows down doesn't mean much. Lighter wheels, or lighter tires on wheels mean less inertia. Couple that with a little bit of seal drag, (worst on new wheels until seals wear in a bit) and you have some very high quality wheels, that won't spin half as long as the cup/cone wheels on a clunker.

    Solving any problem requires understanding the underlying cause

    I am way late to this party, but you might check that the washer between freehub and hub is in place. I have the same wheelset and found this washer missing. My first ride was very dissappointing as my chain sagged severely while freewheeling. LBS put in the washer and all was great after that.
