What A Difference HG Makes.
Well, today I took my Concorde out for a shake down spin. During the winter, I remove the UG fee hub and installed a Hyper-Glide free hub cassettes. The bike is all Campy Athena, including wheels, but Shimano 105 hubs.
The Synchro II shifting system has always been sluggish with Shimano cassettes . Not anymore. With HG cassettes, shifts are precise and snappy, just like my 105 system. KB
