My friend Eds 58cm custom 700 grm frame
Moderator: robbosmans
This is one of Eds bikes 700grms for a 58cm . Ed made all my seat post combos and bar stem combos He also helped customise both my bikes. He his a carbon master see more of his incredible work ,check the link

Impressive road frame, interesting concept using the honeycomb on the exterior and then, potentially 'aero' like a golf ball. It would be good to see that theory tested...

I'm impressed with the frame's weight and concept, but I feel like the writer spent too much time waxing poetic.
Otherwise, nice frame and good luck to your friend future projects!

The reason for the waxing poetic is you really have to see his bikes in the flesh " amazing"
The honeycomb carbon he uses he designed himself. He really his at the cutting edge of carbon and always looking to be creative and come up with new concepts.
Like Kevin [cryptic] he can build frames 600grms -700grms no problem.

The carbon options and lay ups can make for a really stiff light weight bikes.
Like all custom bike makers. you get what you ask for in design.
You still see lots of light bikes with small tubes .

I agree with xena that in a custom bike "you get what you ask for" but I also agree with Valbrona that small diameter tubes in an ultralight frame definitely equals low stiffness.

I'm sorry but get closer to, and that looks like someone's vomited on it

Small diameter does not mean low stiffness in carbon. Its true that a larger diameter tube is much stiffer but at what point does it become too stiff? Carbon has 4 times the modulus of steel and think how small ever "oversized" steel tube sets are. Tube wall thickness is relative. Double wall thickness and double stiffness but diameter is 3 times the strength for double the diameter. The idea that is pushed so much is thinner wall and bigger diameter but at what point does it become too thin and brittle? Drop a coin on the TT and it shatters. You can engineer a frame with "small" tubes in carbon to be very stiff. You just have to find that nice balance between diameter and wall thickness IMO. Thats what I have really been working on.
And yes I loved looking at Ed's frames and his artistic touch is brilliant. Honey comb is something ive always wanted to try in tubing.

I'm sick of this sh4t ..every time I post, some shi5t head like you comes on and puts in a pile of negative sh%t which is basically aimed at me , it happens to often. Go check my posts and you will see .
You have not seen Eds work up close I have. Your being a deliberate MF. GFY and all the rest of you xena haters.
If I get a ban for this post then fair enough but it has to be said. Trolling or being a ar£hole or whatever you call it but it always happens on my posts. your a bunch of jealous tw%%s.

Not all of us do that, Ray.
...also, it's the internet. Try not to take it too seriously!
Ed's work is unique, thanks for sharing.

I agree Prendy. I have no issue with you and fair critic I can take but people seem to just blow off on my posts because its me and I don't know what fair critic is anymore "if you get me" I get attacked so many times its impossible to tell.
It happens on so many of my posts. I make a valid point and I get attacked.
Thanks for you words.

I'm impressed you can tell the stiffness of a frame by looking at a picture on your screen.

I really like the elegance of small diameter tubes and I agree that 'stiff enough' is something relevant (as you say, pros were riding 1 inch steel frames a few decades ago). But, still, I cannot grasp how a 650gr frame with small diameter tubes can be stiff enough by today's standards.
Anyway, I might be wrong I am an engineer but not at all a composites expert.

Excuse me for offering a personal view
I'm not going to stoop to your low level of grammar and name calling, i'm better than that (or so i'm told).
I actually went to the effort to read and look at the pictures provided on the link.
Beauty is in the eye of the beholder, and for this viewer its not working.
It could be the best thing since sliced bread, but if it doesn't appeal visually, then it will struggle ( I've had bike only its mother could love so I know )
There are a lot of great people on this site that are now producing great things (kevosinn, craddock, Berk etc) which is something this site has sadly missed over the last few years. I've loved following their work, and hope they are successful and continue to post.
I'm sure they are all man enough to take any criticism on the chin where its due and also to ignore other stuff. I'm also certain they'd consider attractiveness a major part of their product plan.
The world would be a really dull place if everyone just agreed on what was "good" and what was "bad", and its even worse when people just agree for the sake of it. Likewise it doesn't need people acting like you jumping to name calling and character assassination on their behalf.
