Frame Features /Strength

[Cellmember]

Hi Guys,

I've been in contact with a frame builder seeing about having a custom made up, from what I've been told about my design I wan't to know what you guys think of his way of building a frame.

I was told that A: a wishbone rear end is not a strong as a A or S bend stays and B that round tubing for the SS/CS bridges are weaker than a plate. O_o

Basically I'm just talking about the specs I was after which he was not interested in doing as he believed his way was better/stronger.

I've heard the opposite to what he has told me and have tried both so I have first hand experience with those options.

I'm dumbfounded by what I've been told as I can't see that being the case but then again, you learn something new every day.

Chime in.

I would think single bend stays are stronger than S bend stays

Yeah due to less bends

[barcodebilly]

I would go with a tube brace. I dunno if they're stronger or not

My personal pref is tube bridge as well, I can't see a plate being stronger/stiffer.

Laird?

I do know that some people break frames and some don't. And some folks always break a frame in the same spot (a friend of mine always broke his on the seat stays, near the top tube. another friend always broke his at the top tube/head tube)

Are you breaking a lot of frames?

I know Laird has some heavy hitters on his frames. (if that's who you're talking about)

I say buy one and try to break it.

I'm after a custom mainly due to not being able to find certain frames so It's just easier to have one made up, no I'm not breaking frames, I have had a lot of defected frames not none braking at crucial points mainly just brake bit snapping off *Cough* Fly.

If I'm getting a custom built up I want to have the spec's I'm after not what someone tells me I should have, plus that's not what I'm talking about here, I don't want to mention names that's not my thing, I just want people's opinions on my first post and even better if someone has a professional background on the matter.

Yeah I've seen a lot of "Pro's" on his frames, good to see.

I wonder why Buckworth isn't on his laird frame any more.

So he is basically saying that some of the strongest frames over the last 15 years... are now the weakest? I'll take wishbones and tube bridges thank you very much.

Maybe you should find a new frame builder.

lairds got some nice welds going on but he seems like a bit of a tripper, especially if hes telling you plate bridges are stronger than tube ones.

i heard wishbones being more twisty is true though, but i guess it depends on the specific dimensions and stuff cos sunday frames

Bro, do you even Barcode?

Whoever told you this, I would completely ignore in future

I've heard from several reputable sources that wishbones greatly strengthen a frame. Not sure about the whole plate/tube argument but tube should take forces better and be lighter. If you want to build a strong and stiff frame, I'd opt for something with large diameter tubes, gussets, a wishbone (or two), and non-micro dropouts for more weld contact area. Basically build a sunday.

nah brah, not trails enough. im awaiting delivery of an AOD though in all its wishboney goodness

If Im not mistaken Mr. French made an article somewhere stating that wishbones are stronger.

I wonder if 3D printed frames could become a thing.
