Weights/comparison for Groupsets
Postby MichaelB » Tue Apr 22, 2008 1:09 pm
But would like to know if there is a site that can give some details of overall weights of groupsets/individual parts.
Looking at a build for the next bike that may or may not include the Cinelli frame that i have
Cheers

Tried that on Shimano page.sogood wrote:What do you want? All those data are published and can be obtained though the web sites of the three majors.
Basic query is for the 105 Cranket & BB, what is the combined weight, and how does it compare with Dura Ace, and something like a FSA K Force carbon crankset ?
I am toying with some ideas for the Cinelli/next project bike to replace the LeMond, on building a bike that is a good workhorse, but being lighter within a set budget.
I had a look at Weight Weenies, but some of the data is incomplete, scattered throughout the site/forum, anecdotal or questionable.
Some of the manufacturer sites have some data, but not others (e.g. Crankset weight, but not BB weight).
The query is that given with a set of Mavic Aksium wheels (not light), and a Campy 9sp Veloce groupset, if I upgraded to a good level groupset and good wheels, how much would the weight reduce by from the current 10.3kg ?
"Who cares", I hear some say, weight is not everything.
It isn't, but I don't want to build a heavy dream bike if I don't have to.
I don't want to save 50 grams at a cost of $500, but if for judicous part selection I can get a kg or so off, then well & good.
That way I can cherry pic the best bits for longevity and function.
Cheers

So if it was just weight vs price then Centaur is the option to go for.MountGower wrote:Michael
There are some interesting graphs here. Centaur really looks like enormous value when you look at it's weight and cost.

Try Chain Reaction or similar retailers, they typically have weight listed for their products.

If the weightweenies stuff is a guide, many of the 'actual' weights are up to 5% more than claimed. On a 2.3kg groupset, you're then up to 2.41kg. Not a jump worth jack shite, I know. But if weight is your underlying enemy, that 100grams could bring you sub-10kg.
Again, all theory...
Looks like the Centaur is a good pick if you like Campy. That'll probably be my group of choice when I redo the project I've got in mind after seeing the link in MountGower's post.
Good luck on your noble quest.

The comparison, of course, is with the Campy groups. Someone correct me if I'm wrong, but my understanding of the higher end Campagnolo groupsets (I've actually got their 2008 line up brochure free from Ribble Cycles!) is that they are VERY similar from the point of view of the actual parts, but, there is increasingly more carbon fibre/lighter weight sub-components.
It seems to me then that you are definitely getting less value for money as you go up the Campy food chain.
Cheers.

No different to anything in the market place. It's about point of diminishing returns.vitualis wrote:It seems to me then that you are definitely getting less value for money as you go up the Campy food chain.

Interesting thread.MountGower wrote:Michael

Problem is, whilst some of the things with my short flirtation with Campag were very good, the thumb levers just don't quite fit with me.
Mind you, at Chain reaction, you can get a full Durace 9sp setup for less than 1K delivered !!!
The graph is good, but still doesn't quite get what I want.
One some parts they do (Shimano), and others they don't. Then with others, they list the same weight for all 3 levels of chainssogood wrote:Doesn't Shimano's web site list the weight of individual components? I am surprised.
Try Chain Reaction or similar retailers, they typically have weight listed for their products.
Some of the key suppliers list the same weight as OEM pages, and some do for some components and then not for others
Oh well, will keep looking and see what i can find.

Dura Ace Crankset + BB - 740gm
FSA K-Force Crankset + BB - 780gm
Campag Centaur Crankset + BB - 877gm
So, the question has been answered, sort of.

Using the Shimano example, I would tend towards buying a Durace group set and replace the chain components as they wear out with Ultegra or 105.

Didn't see the table below ....wayno wrote:Ahh yes it does the text does not line up.
105 crank 766g Dura Ace crank 639g
Or just buy the latest RIDE mag, in the CR1 review has all actual weights
The latest BA magazine also has a good comparo between Dura Ace, SRAM Red and Record.
