Hi Rick,

I'm not sure I understand what other information you want. Is it where the frame is made? How is the frame made? How it is sized?

From the picture on their site it looks to me that the bike is made with a monocoque method. The details of that method would be proprietary and frankly unimportant to a buyer.

Is the frame made in the USA? That I can't tell you either.

For that matter, do you care where the frame is made? If so, why don't you care that that drivetrain and shifters are made in either Japan, Taiwan or France?

The kinds of questions I would have are along the lines of whether the frame can be customized to fit my non-standard body.

I can tell from the Seven site that it's not the kind of bike that I would want, but that's just me. I have a full custom carbon fiber Calfee Tetra Pro already which I am very happy with.

Until I hear back from you I'm flying in the dark. Just keep in the mind that a bike is a package that makes a machine that interfaces with you. The questions that would be important in this case would be, does it fit? Is it suited for the style of riding I want to do? Is it worth it to me? (the last question is tough because that is purely personal, after all, any custom bike can be a very expensive proposition).

Cheers to you. I will say that Seven Cycles makes excellent products. That said, like any custom builder, it's only the frame they customize; all the other parts you work with an LBS to specify.

Well i guess the true problem is me. I am not sure what i want and jump back and forth from race bike to one with a bit softer ride. I am still looking at the right bike for me and it seems that i have only read good things about seven and the fit. I like the look of the diamas and it seems to be more of an aero design like the cervelo soloist, but with no reviews of the bike i am just not sure. The price for the bike does not matter at all I want the best bike and components for me. So how come you dont like the Diamas? is it the none traditional look? and any ideas would be great. Believe it or not when you take price out of the equation it makes it harder not easyer to find the right bike.

Hi Rick,

It's not that I don't like the Diamas per se. I'm 53 and an avid recreational cyclist. My Calfee Tetra Pro, for example, was ordered to be able to take a rear rack. Once the moderator approves the pics I uploaded you will be able to look in the picture gallery to see the way the rack is simply mounted. So for my purposes, a race bike does not suit me. This is the only reason I wouldn't get a bike like that.

I suggest you do the smart thing. Get thee to a local bike shop that is big on proper fit and talk, talk, talk about what you like about biking and what you think you want to do. For example, classic race bikes were made to be light and comfortable for racers. After all, they would spend hours riding circuits that included cobblestones. Find out, through your local bike shop exactly how well your fit can be made on the Seven bike you are thinking about, in the geometry that you desire.

You should learn about fit by going to a lot of web sites of custom bike makers. Many of them have strong opinions on proper fit and talk about it. My fit was determined by getting a professional fitting at the bike shop I had a great deal of confidence in. I subsequently got a full custom Calfee based on my fit measurements. It suits my go-fast avid recreational and fitness riding style and takes into account my core strength and issues such as my back and knees.

For what it's worth, aero is only a fashion for most folks. Only a racer benefits from an aero bike, and only by very small margins in a time trial at maximum power output. For mere mortals there is no discernable difference in performance between an aero bike and a normal tube bike. Another thing to consider, even on a race bike, you can get a soft ride with the right choice of tires and inflation pressures. The compliance of tires are the most significant factor in the softness of the ride of any bike. Everything else about the bike is uber stiff compared to the tires, even if the bike frame has a reputation for being, "soft."

Get any bike in the $3K range that is properly fit to you and you will be happy, if it's the right kind of bike for the style of riding you do. A cyclocross bike, for example suits a particular style and can be a good all-around fitness bike as well. A time trial geometry puts your body in an aero position to minimize drag and is not a suitable bike for much of any other kind of riding since it's actually an uncomfortable position you are in.

I would add some more thoughts.

A racing bike like the Diamas has short chain stays to tuck the wheel in tight against the curved seat tube. That short wheel base makes the bike feel faster. It also makes it most important that you have the right size frame because weight distribution front and rear are important for maximum control and performance. Longer chainstays make a bike that rides more smoothy on rougher roads.

It is the trail of the front geometry that determines how twitchy the bike feels. Oversteer, understeer and neutral steering are determined by the factors of head tube angle, fork rake and wheel diameter. A bike can be comfortable, yet fatiguing on long rides if you have to put a lot of effort into controlling a bike with short trail (oversteer).

These are the kinds of things you learn about bike fit and geometry that affect the performance of the bike. These are the kinds of things you learn, with experience, what suits your riding style.

thanks for the insight on fit and feel. You talked a bit about back pain so i figured i would post a link to 3 articles I have written on backpain and cycling for pezcyclingnews.com as you can see I am all for proper bike fit. I have gotten great feedback about the series and have helped a bunch of people with a few shops in the area. I have a trusted shop and fitter. I just need to make a choice as to what geometry I want.

I have a 2002 Alaris and a 2005 Elium.. The Alaris geometry was pretty much decided by Seven.. 3 years later I knew what kind of position was best for me. The Elium was by my LBS because he knew what I wanted. Seven did not agree with him and he had to argue to get the frame as it is now. Seven wanted to build the Elium with the same geometry as the Alaris...I am not the same rider as I was 3 years ago, but that didn't matter to them, they go by measurements and a form you fill out. I love my Elium and since then have replaced the fork, stem and seat post on the Alaris to get it as close as possible to the Elium in geometry.. What ever custom frame you decide on, make sure your fit is proper and get what you want.

My LBS lost their Seven distributorship 6 months after I got my Elium. Coincidence? I am not sure, as they gave it to another local small LBS.

Thanks for the insight. I have decided to go with the Diamas but i am going to see how my LBS fits me and then see what seven has to say. I am then going to try and set up my present ride to that as close as i can and see how the fit is. I know the geomety will not be the same but I think it will help. I also have another locale guy who is a well respected guy on fitting so I am not sure I may give him a call also. The thing with Diamas is once the seat height is set thats it its part of the frame. I just want to make sure the fit is right.

oh and by the way did you guys see the new campy 07
