I spoke with my local bike dealer today who told me that your Campy drovetrain will always sound louder than Shimano because of the mechanism used to make the gear shifts. Basically he stated that while Shomano builds some plays into their shifts and uses a spring loaded mechanism, Campy on the other hand does not build any play into their shifters (this is why it takes them awhile to break in) and also the mechanism for making the shifts will always result in as he called it "plunking" the chain from sprocket to sprocket which causes the noise. He further explained that this noise never leaves the Campy drivetrain even after its broken in, it just a different way to do the shift versus Shimano and it will always be louder and more noticeable according to him. He also stated that the fact that Shimano intentionally builds play into their shifting mechanism is so that it functions perfectly with no break in period out of the box. He also said this is why it gets worse after a long time because the play gets bigger and bigger. He also said he thought it was unimportant that the Shimano play eventually resulted in poorer shifting because he said this takes years to occur for your typical rider and by then you are usually upgrading to a new bike with new drivetrain technology, which seemed to make sense, and that you could eliminate the excessive play by simply buying a new casette.

Any opinions on Record and Chorus versus Dura Ace and Campy.

Has anyone seen the 25 anniversary edition Dura Ace. I saw it today on a Merlin Extralight and it looked like jewel quality finish.

The "plunking" sound you are referring to is 'primarily' a function of how much load is on the drivetrain. I've heard Shimano riders "slam" gears and I've heard if from Campy riders..... again it's a "loading" issue mostly. I'm a Campy rider, but the Ultegra bikes I've test riden really didn't sound any different to me. Maybe I wasn't really paying attention at the time but I usually notice that kind of stuff. shifted just fine

The MUCH bigger difference between Shimano and Campy is the hood design and shifter ergonomics and the 9/10 difference. IMHO, you should decide on these factors and not worry about this "bogus" sound issue. There was also a link to a very detailed comparison between S/C recently posted.... search for it and check it out!

good luck

I rode 105 for a few years and this year switched to Chorus. I choose Campy in part becuase the 16 tooth cog is a surprisingly important omission from Shimano - to convince yourself, caluculate the ratios - the jump from 15 to 17 is surprising.

Also, I never noticed any noise difference with well adjusted set-ups. A friend riding Ultegra ohhed and ahhed about the smooth, quiet shifting of my Chorus group - but I really don't notice either... JohnG is right, noise is a smokescreen - find the fit and gear arrangement that works best for you.

Did he try to sell you any Florida swamp-land ? You need to discount everything he says about 75% and then ignore it. I wouldn't buy anything from this guy, he's blowing smoke. Seriously, if you keep the chain clean and properly wet lube the chain, like Campagnolo recommends, you won't believe how sweet chorus sounds.

LOL, thanks, that was funny. Perhaps I should ask himn if his pen name is Stephen King? Thanks for the info, now I need to decide between Chorus 10 or Chorus 9 for 2001. Decisions, decisions.
Gotta ask.....JohnG

Why on earth would you get C9 when C10 works sooooooo good????~~~

Oh, I've got about 4500 miles on my C10 drivetrain and the C10 chain is less than "half worn". Any comments about C10 drivetrain reliability will get you severely reprimanded ... ;)

Just say NO to Permalink

I've got close to the same miles on my Chorus 10 and have never wished that I went with 9-speed. Unlike John, I'm still running the Permalink. However, I may make a switch when it's time for a new chain.

Gotta laugh out of your death ride post. Man, it was Hot last weekend! I'm heading up into the hills to see if I can make it up to Bear Divide with a 23. Yikesss.... ;) I might be road kill myself later today.

On Friday I didn't leave the house until after 8:00, which is really late for me. I headed up into Westlake Village and Thousand Oaks, rather than doing the sane thing and going over the pass to Santa Monica. It feels like the temp dropped a few degrees today, but the humidity increased a little. I left the house at 6:00 a.m. today, so it wasn't too bad. Hope to hear from you again after today's ride. ;-) Be safe.

Choosing between a 9 and 10 speed is a no brainer. Campy will be switching to all 10 speeds.
