WTF? Lugged carbon frames??

Notices
Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Lugging the frame makes it much cheaper to make frames from 43-63cm. Think of how many molds they would need to make one piece frames, you need fewer mold for luges for the same range in sizes and they would be cheaper to build. Then you can cut tubing to size.

This is one reason I think compact geometry has become so popular with the manufactures.

Manufactures used lug frames just to cheese off folks like you who don't know/care enough to actually look into something before they post nonsense. Lugs for CF are economical and allow a manufacture to offer more sizes with less costs to themselves. Monoque frame molds are expensive.... do you're own research.

Dude I know sin Sincitycycler has cheesed a lot of people off in the forums but you don't needed to be so hard on him "There is a world full of the wonders of information beyond your belly button if you're curious enough to engage it." is this real needed could have said try Google etc...

Noted and edited! Sorry to be so harsh there Sin...just do a little research and then post, or say something like, "What the deal with lugged carbon frames? Why this and not monoque?"

Also, I'm pretty sure that Treks are monocoque frames. Large companies that sell in high volumes (Trek, Giant) are a lot more able to pony up the tooling costs to make molds for carbon bikes in every size, but smaller companies have to get away with just molding their lugs and varying the lengths of carbon tubes to create different sized frames.

Some may also use lugs but wrap extra carbon around them to hide the lugs. Youll likely see this become popular if its not already done. It would be a good way to go to make manfavutring the frames easyer and still have the smooth sleek look. All they would need to do is make extra molds for the lugged area. Alittle finishing work with sanders and polishers and all set.

Lugs also increase the thickness at the joints makeing the join stronger. Carbon fiber to carbon fiber and you dont get expansion problems or other problems like you do with carbon to ti or carbon to aluminum.

What you wrote definately makes sense but at some point in volume monoque molds are probably worth it. I say this because the Fuji carbon fiber frames are monoque construction, and offered in a multitude of sizes. And I consider them one of the best deals on the market.

because of the pricing giant makes their standard sizes of s,m,l,xl. saves a lot of money but that way they can stay current with technology and no longer use lugs.

The lugs on the bike are not there for show - they are the structural members that hold the bike together. Same exact purpose/function as lugs on a steel bike. Trek bikes indeed use lugs. Their lugs, of course, are internal. The ends of the lugs fit inside the tubes, whereas the lugs on most steel bikes and most lugged carbon bikes are attached around on the outside of the tubes so they are more visible. There are disadvantages to manufacturing frames "monocoque" style. It is generally more expensive and in general cannot be made in custom sizes for this reason. Also, the monocoque frame often has a leftover air bladder or hard foam core left inside which may add weight.

S-Works,Roubaix,Giant TCR,Tarmac,Tarmac E5,LookKg480. I belive these are a few that are Monocoque. It seems that one peice would be stronger then lugging.

I actually like the look of the lugs. The makers should be proud of them, like they were with the steel lugs. Wouldn't it be cool of the lugs were white or red carbon to contrast the black?

You are right on the treks, however your orbea is also lugged.

You need to check your information. I know my Orbea is not lugged. It is monocoque, at least according to the catalog and all my paperwork.

it may be a monocoque headtube or something, but my friend has the orca and it has giant lugs at the seattube and bottom bracket. Check it out on yours.

Sorry about the size of the picture, but this is a picture of my bottom bracket area...no lugs that I can see...dont have a pic of the seattube...

Carbon bikes made in the USA, including Trek, Calfee, and Parlee, are mostly lugged. Carbon bikes made in Taiwan (Giant, Specialized, Martek, etc.) are generally monocoque. I have no comment on Lance Armstrong's sexual preferece.

Lugged or Monocoque, both look good to me

I like the monocoque designs more, however there are a lot of fine lugged models I would be more than happy to own.

As stated Molds are expensive to make, and as such carbon tubes with lugs is good enough for a bicycle.

Strange though how a lugged Carbon Colnago C50 can cost more than many other makers Monocoque frames

maybe it's different from the orca, but that wouldn't make much sense to me..

I went and looked at my bike again, and it seems like it is monocoque and lugged. While the joint at the seattube/toptube doesnt seem to be lugged, the seattube meeting the downtube seems to be. My joints dont seem to be as "pronounced" on the pics you provided though.
