Mystery and Unidentified Parts

Definitely in the titanium weight range. Pretty sure my Merlin bar is a little heavier than that

Hi, is anyone able to help identify these cranks, they're currently on a Pace RC200 F2, but need to find a new pair/single left crank as they're on their last legs!

Well on a Pace I would say Bullseye, but the clamping area looks like pressed steel. There were similar (BMX) cranks from other brands. They probably would be easier to identify from the drive side?

Cheers for the reply, here's a pic of the drive side

I have these handlebars without markings that I thought might be Tange steel though it turns out they're not magnetic and they don't appear to be aluminium as the walls are thin. They have the hue of titanium, I thought they might be nickel plated though a few nicks seem to show this is the natural colour. Is there any other way of checking to see what metal they might be? Cheers

Looks ti -
although stainless is hardly magnetic, but an unsuitable material for a bar due to fatigue life.

It could be aluminium with a ti finish, but the walls look little thin.

You can measure the density by submerging the bars in a suitable container full of water, then remove enough water to drop the level back to where it was before you immersed the bar.

Weigh this water - from which you can calculate the volume (1g/cm³)

Density=weight/ volume
Steel 8 g/cm³
Titanium 4.4 g/cm³
Aluminium alloy 2.7 g/cm³

The differences are considerable.
