How do you tell..........

Well I'd say their not Aluminum and if your magnet doesnt stick its definitely Ti :shock:

Have you got a multimeter handy? (or even a battery & bulb combo)

...Assuming that if the bars are alu, they will be anodised, you could test their conductivity...Anodising is an insulator, whereas bare Ti will conduct happily.

Or roughly estimate their volume? (Length x cross section). Ti has a density of 4.5 g/cm3, alu around 2.7g/cm3. These densities are far enough apart, a rough estimate should easily tell.

All the best,

They're titanium. There's an identical pair here:

FWIW I'd say the colour is pretty clear. I've never seen an aluminium surface treatment that really resembles the darkish dull grey of raw titanium.

Thanks for that, they're definately the same ones!

Looks like Carbon Fibre!!

Just in case you need any further proof. I can confirm that these bars are titanium. I had a set exactly the same that I bought on ebay a year or so ago. They were advertised as fat chance bars although there was no evidence that there was any truth to this. I returned them to the seller as the bars were out of true when place on a flat surface and I was unable to straighten them to my satisfaction as the distortion was in the twisting and shaping of the tube when the bars were made.

They were definately exactly the same though, in fact they might even be the same ones

What about a sound test as steel has a resonance that when pinged that alu doesn't in comparison. Does Ti have a resonance or is it dull like alu ?

Agree the welds unless they're smooth like Canondale are likely to be a dead giveaway.

Ti rings like a bell. Cracked Ti frames make excellent windchimes :shock:
