agree with advice to pass on a Cannondale with a Headshok
for many reasons
however - given this - I've been casually interested in this design since I saw an early Action Tec fork (similar design that predated the Headshok) - and I searched for a Cannondale hybrid with a Headshok ... with the hope the short travel / low-tech version of the Headshok used on the hybrid (elastomer/spring(?) - no air) would be less trouble
I really like it - for the application ... works well and provides a smooth ride over the irregular surfaces
the resulting odd raised front due to the Headshok results in a higher handlebar which for many is a plus on a hybrid
there is at least one shop that currently specializes in Headshok service
