I got used to assembling my own bikes and to be economical, I got used to using any old triple FD, usually a Shimano. But when I ordered my AHH from Rivendell a few years ago, I decided to pull out the stops and have Mark assemble it. I needed a FD and trusted Riv's selection, and they went with a Campy triple model called the Champ.
That is the smoothest and fasted shifting front shifter I've ever used. I never was picky about FD performance and can still tolerate slow, laborious shifts, but my experience has definitely been: Shimano: pretty good, just deal with it The one time I've used Campy: outstanding -Jim -----Original Message----- >From: MichaelH <[email protected]> >Sent: Jun 19, 2010 12:38 PM >To: RBW Owners Bunch <[email protected]> >Subject: [RBW] Re: Shifting issues with TA Pro 5 Vis cranks/rings > >I can confirm this.
