You guys, quit your *****ing and go ride. Leave the thumb shifting for the MEN who adapt and overcome..HOOAH!House said:Shimano, simply because I hate the Campy thumb shifting lever. Having used both this is the only real difference between them, they are both great stuff.
mitosis said:I just hope all you traditionalists admiring the look and shine of your Italian bikes with their Italian group sets are not using a computer of any sort on your bikes if you ever find time to ride them.
If you look closely they are made in Taiwan, China or heaven help you - Japan!
And don't forget to calibrate them in kilometres.
Steel? What's that?teammiyata said:It is kinda funny though how the Italians came up with a marginally better group while the Japanese produce a far superior lugged steel frame.....at least they used to.
And for an end user like me who is not concerned with all the things you have just mentioned. Namely because both work equally well despite the factors you mentioned. Stiffness cannot be felt and should not even be considered. (Petacchi uses C). Campy is the Mercedes Benz and the Shimano is the not too shabby Acura but PLEASE! stop comparing them. The only people that love Shimano more than Campy are those who have never used Campy.robkit said:i agree with all who have rightly pointed out that neither DA or Record could be cr@p else one or the other would not be around. however, having in the last year built bikes with DA and Record, and ridden both, I feel there are several reasons why Shimano is clearly ahead techically:
1) S are 2 iterations ahead of C in the technology used to attach the chainset to the BB, namely Octalink & Hollowtech. The result is now a measurably stiffer connection than C, as detailed in this
http://www.duraace.com/publish/content/duraace/en/home/the_product0/drive_train.ExtraMainContentPar.0017.File.tmp/VN-crank-results-web.pdf
As stated above, C use carbon for cosmetics, not stiffness. Meantime S recognise that carbon is used in eg the rear triangle of bikes to promote stiffness which translates into superior power transfer, and thus concentrate on building stiff cranks.
Besides this you need a simple allen key to fit/refit a DA chainset, no crank extractors, etc.
2) S shifters are ergonomically better than C, in terms of hand comfort and especially for changing to smaller rings, plus the shifting itself is significantly lighter. The cables are on show because this makes for lighter shifting, it would be a simple development to route them, but S chose not to do this.
3) S brakes are more powerful, C brakes are clearly a more basic design of the kind S tend to use on the lower end groups.
The issue of where to put the quick release for the brakes is resolved when you try to use a different set of brake levers - eg for a time trial bike. C users are left with no quick release. And the S design allows for phased release - with C its all or nothing only.
4) Ever tried to retrospectively fit an ergobrain? Requires complete removal of hoods from the bars and all the work that goes with it. S requires peeling back the rubber and removing a plastic blank with 3 screws.
5) As to repairability and durability, it is a fact of life that things engineered with tighter tolerances tend to wear out sooner. This cannot be considered a defect, just a matter of choice by the user. The most expensive tyres will wear out the fastest due to choice of compound, this does not make them inferior unless your main evauation criteria is longevity.
To the defense of C, because i am trying to be objective, yes they do offer a better range of headsets. Unsure why S havent addressed this. And of course they are miles ahead in the wheel market.
Looks like we're sprinting yet to another redundant argument.996vtwin said:And for an end user like me who is not concerned with all the things you have just mentioned.

Why would you choose the Fishing Rod over the Italian Stallion!

lyotard said:ah perhaps we recall 3 Rensho, Zunow Hummingbird, or perhaps a long point from Mr. Nishiki himself. and of ishiwata triple butted, yes?
mitosis said:I forgot to add that you should be on a steel bike with solid tyres monsieur tradition.
vortex3d said:How'd you know that's what I train with? Damn! you're good! I better keep my secrets more secure.
teammiyata said:yes yes, don't forget Bridgestone, Nagasawa, Kalavinka, Panasonic and (drum roll)...Miyata.
the really sweet Ishiwata was actually quad butted but was bested by Miyata's spline triple.
random facts that vaguely gives this thread cohesion:
1)NASA has used and bought patent rights for tubing specifications from Japanese bicycle companies for use on the space shuttle.
2) 1 in 3 satelites currently circling our planet are being held in place by gyroscopes whose bearings come from Italy.
I had a point but I like totally forget what it was.
