Anyone know anything about mag frames? I have an opportunity to pick one up locally for dirt cheap, but I'm concerned, as I don't know anything about it other than it's quite light (sub 3lbs). Not much info is available online, except from the frame's manufacturer, Paketa, and I'm not too trusting of that. Anyone had experience/can guide me in the right direction?
Magnesium Frames
- Thread starter blue
- Start date
several different makers that have frames out right now and i've heard good things. i also heard how well it burns.
i rode a similar frame for a while. Held up great, and it was simply the lightest thing in the world. I think it came out to around 2.5 lbs for a small size frame. It's still sitting around, just not built up anymore... held up to my 190 lbs doing trials and w hat not.
Magnesium has strength and weight properties that are similar to Aluminum, maybe a little better strength to weight ratio. But like any bike part the devil is in the details of how well it is designed and built. Magnesium is not used that much because of it's flamability. I saw the results of a magnesium fire in a cnc machine and it was not pretty.
i wanna see one of those catching fire!!!...
on the other hand i wonder.. how hot is has to be to light magnesium??? i´ve seen mag rims on cars with glowing brake discs and they didnt burst into flames... i guess the temp at which they catch fire must be pretty high.....

Magnesium in a powder form will readily ignite with just a spark 
Most fork lowers are magnesium so no reason to think a mag frame is a fire hazard. Any metal will burn at some point. Some fine steel wool, a match and some huffing and puffing will result in some serious heat.
Use the contact points of a battery with steel wool and you can have a lot of fun. Don't ever store the two items in the same drawer.....Westy said:
Magnesium powder will flash and explode real quick, quite fun if you have alot of it.

lowers burn nicely!!!!Westy said:

You can use magnesium to ignite thermite. You can do some real damage with thermite, and it is not that hard to make.ito said:

We used to sell them at a shop I worked for in AZ back in the late nineties. Saw a bunch of failures around the seat tube area, but it was probably just poor design and not any fault of the magnesium.
They were damn light! ~2.6 pounds. Can't remember the name on them, but they were out of Hungary. I want to say Lodestar or something like that. From what I heard, they rode pretty well.

just dont ride with me if youve got a magnesium frame. ill be chasing after you with a lighter. :devil:
Yep..those are the ones I'm looking at. I think I'm going to wait out a Homegrown auction, and fail that, I'll get a mag frame. No disc mounts, though. Anyone have a good, cheap disc adaptor? Brake therapy=$$$...RD3 said:
have your local welder weld some disc bosses... and dont tell him is magnessium...
but seriously, i think they are too light to gamble putting some disc tabs on them..
how much are they selling for blue where you say you can get them locally??

They're going for 150 from that same guy on eBay. However, if I want a scuffed silver one, I'm gonna pay 130. I want a yellow one though...mmm. Before I was deep into mtbing, about 3 years ago at a shop they had a yellow Salt Cycles hanging on the wall and I thought to myself "Wow, those mountain bikers are crazy to pay that much for not even a whole bike". I think it was around $1k.
It's cheap enough that I wouldn't be worried if the discs broke it. I'd consider selling my XT stuff and going to v-brakes, but the fork I'd be using is disc-only, and disc front/v-brake back looks weird...
Got one. 19 inch, yellow, I'm guessing it will be here on...Thursday, unless the seller agrees to a local pickup.
Let us know how it goes, then.
It will go well. And you should buy my GT. Five-Hundre dolla!Darkreaper said:
Too busy with A-level exams. Once they are over I'll be touring bike shops round here to get a feel for the frames, then I might get back to ya.
Not buying your GT then
How goes the mag frame?
How goes the mag frame?
I just sold it to a guy in Austria over eBay.
The mag frame is here and not built...i've been tooling around on my gf's Azonic for the past 3 weeks. I need a headset and seatpost before I can do anything.
I've met guys at races that have had the mag frames and they loved them...only problem was the lack of disc mounts and that if you don't penetrate the seattube enough with the post, the frame cranks.

How much did you get for it? Guessing the sale of it goes towards a thompson and CK setup, eh?
