After riding Campy (Centaur & Chorus for 'cross, Record for Road)for fifteen years, I recently rode Ultegra 10 spd for a month to become more familiar with the product. It’s a great gruppo: The shift levers are, in my opinion, ugly; however, they’re ergonomically very nice, and the reach from the drops is great. I always hated Shimano’s cable routing because it limited my hand positions, but the new levers provided me with plenty of places to put my paws (Oddly, I didn’t like the way my hands wrapped around the levers while standing, but that’s a very personal thing and speaks to the size of my hands more than anything). Campy still fits me better, but that’s just me.
The rear derailleur has an ever-so-slight hesitation when moving up and down the cogs - noticeably slower than Campy, but nothing to fret about. It’s just that Shimano seems to start shifting after you click the lever, while Campy seems to do so as you’re clicking - very small difference. The shifting up front is, I dare say, easier and quicker than my Record (I know, blasphemy!), but you give up trim settings for the very slight difference, and the difference isn’t enough to make me forget that. For the life of me, I can’t understand why Shimano continues to ignore this complaint (the lack of trim settings, I mean, but that’s a shifter issue actually).
The whole Crankset/Bottom Bracket thing really cracks me up. First of all, it’s no secret that the new Shimano bearings have met with many of the same durability problems that the Sweet cranks had many years ago (my Ultegra’s gave up the ghost within a week in wet weather). For anyone to say the quality of Shimano’s BB or bearings, new or Octalink, are better than Campy’s tells me they know not of which they speak (sorry, no offense). Campy obviously has the edge in quality here, and if your argument is about strength/stiffness, that doesn’t fly either because: a) you’re not strong enough to flex the cranks to notice the barely measurable difference, and b) the frame, tires, and wheels will deflect under load long before the cranks. Nothing wrong with the square taper design, ask Petacchi what he thinks of them. Oh, and with Campy, you’re cranks/BB aren’t outdated in a few years (I’ll probably eat my words later in the year when Campy comes out with their new design, but I believe it has more to do with bearings than interface). Having said that, I like the simplicity of the integrated Crank/BB, and think the quick shifting up front might have something to do with the stiffness of the chainrings. Still, I can’t get over the looks (although Ultegra looks better than Dura-Ace, IMO), and nothing looks as good as the Alloy Records. I’m not a big fan of the Marble look of Campy’s carbon cranks either.
The brake comparison is as it’s been for twenty years. Shimano’s grab better than Campy’s. However, for Campy, braking has always been more about trimming speed, while Shimano has opted for pure stopping power. Both will bring you to a stop quickly enough, and Shimano has certainly upgraded their brake’s modulation ability since I last rode them.
I won’t address wheelsets (much) because so many opt for aftermarket stuff, but hey Shimano…Yawn…while you’re adding trim setting to your front shifter, how about a little creativity in your wheels. And not creativity for the sake of being different, do something worth while! I know, I know, Dura-Ace tubeless is just around the corner. Blah, Blah. Record hubs are still the standard by which all others are compared.
In the end, all of the groups listed in this thread will do what they’re suppose to do…click, shift…click, shift. There’s nothing about any of them that will cause you to win or lose a race, neither offer enough weight difference to matter much at all, and all have become ridiculously expensive for the relative simplicity of what they do. It’s really a matter of personal preference. Just my opinions, but I see no reason to own either Record or Dura-Ace for anything other than the “Gucci Factor” both groups bring. Nothing wrong with that, just be honest with yourself before spending the money. The only place I see Campy having it all over Shimano is in time. That is, if you’re the type of person who expects to keep his/her bikes and components for more than five years, and you do a fair amount of training, than your obvious choice is to go with Campy. Their stuff lasts longer, is repairable, and they rarely outdate their designs - you can always upgrade (or downgrade, for that matter).
I enjoyed my month of Shimano - the stuff worked great - but, alas, my Kredo is now adorned with Record and I feel at home again.
