nice !

.. does it work ?

[Macbeth]

I don't know a lot about metals, but I know a lot of you do.... Isn't magnesium one of the most malleable (soft) metals there is???

[tigerxiao8]

don't know yet, in test

Word... But if its mixed into an alloy right it can be pretty strong i think?

I know Dymag wheels on cars are carbon/magnesium alloy bonded together.

There are also DOB magnesium frames and rims, and various magnesium pedals.

[Dang!]

From what I understand, Magnesium has a strength similar to steel, it's harder than aluminum and weighs less. But I think it can be brittle? And hard to come by.

Where are you getting these Magnesium tubes?

[Macbeth]

Reason I ask is that the magnesium lowers off a lot of XC suspension forks weigh more than these complete forks....

The boss at the first bike shop I ever worked for had a saying - 'Strong, Light, Inexpensive, Choose any Two'

Just wondering how they will hold up, theoretically....

[Peace]

Steve Hogg definitely has a good point with the choose any two thing....

They just looks and sound dodge.... but thats just scepticism at the moment.

I'll test one

Modulus of elasticity is a direct correlation between material stiffness, so:

Steel = 30,000,000psi
Aluminum = 10,000,000psi
Magnesium = 6,500,000psi

Hence, the reason the cross-sectional area is larger for materials with a lower section modulus. Just the facts…

[willbed]

I kinda like that... Of course Mag isn't good for any rider... Definitly not quite as strong as aluminum...

Stripped threads on Mag stems
Rider weight limit and tire pressure limit on Mag rims
Mag bolts can be used on rear V and HS33 brakes
I'd only use Mag bolts for a front brake if it was for a road bike with front brake mounted behind the fork...

Disc tab might be pushing it a bit IMO... Would be curious to see FEA results... and compare with rim brake mounts on the back of the blades... The only possible problem would seem to be with hooks pulling the brake out of the fork, but I guess the fork would fail before the brake comes out...

Really interesting though

dno
the dob stuff isn't magnesium so much as magnalium
maybe these forks are the same?

edit: messed it up :) I thought about Sodium.. sorry.

[Tanner]

...if you ride in hydrochloric acid...

[rush]

Thats how they roll in Sweden

[WuYang]

yes, mixed Aluminum&Magnesium

but aluminum frame is still a little stronger than a mag one in fact

classic. it'd have been a nice touch if the narrator walked into the frame and gave mary a congratulatory pat on the ass.

I noticed there are no notches on the dropouts to keep the bolt/quick release from possibly slipping out. That is a little danger.

no lawyer tabs = mechanic's best friend. Makes super fast wheel changes so much nicer.

do up your quick release then dude.
