in terms of comfort, weight and strength. Thanks.
Better than what?Kerry Irons

My standard answer is that design is a lot more important than material, so such questions are not real revealing. That said, is there anyone making a Mg frame right now? Mg has been a wannabe bike frame material for the past 40 years, but has never caught on. Many reasons have been given, but the fact that it just hasn't happened may have a message. Even if it is the next wave material (haven't heard that anywhere, but let's just suppose it is) then there would likely be a lot of changes in the next few years as things sort out. This certainly happened with Al, Ti, and CF. Not to say the first frames of these materials were bad, but things evolved quickly, leaving the early adopters feeling the need to upgrade. If you've found a leading edge Mg frame you like, go for it. But there really is no "settled wisdom" on the properties of Mg for bike frames - too few (if any) of them around for any conclusions.

I seem to recall someone on this forum saying that Mg frames were horrifically flexible ... and that one tester caused the frame to flex just by getting on it.
That tester may have been me...Leisure

The frame I was looking at was ridiculously light, I didn't even "test" it per se because it flexed so much; the BB shifted as much as two inches to the side when one of the store empoyees put his foot on the pedal. The store didn't recommend it, they only ordered it because a customer absolutely had to have the lightest, and wouldn't be convinced otherwise. I dared putting my foot on the pedal as above with similar results, but never sat or rode on it. In my hands the frame felt as solid as a tin can. I even felt a very slight crackling sensation when I pinched the frame between my fingers, although that could have been the paint. A lot of these observations are largely the result of how the company chose to implement the material, but it's the only company I know of that's invested in magnesium tubing, and they're now out of business.
Ti on the other hand is being used by a whole bunch of established, fairly responsible companies. The frames are praised by most customers of each. The numerous material benefits are well-known. Easton is about the only company making anything out of magnesium, and none of it involves frame tubing. Until something comes along to radically advance the application of magnesium, this is a no-contest issue.
