Titanium Freehub


BIGA1

Recommended Posts

Titanium is great structurally because it has a high strength/weight ratio. It has a strength less than that of steel but weighs a lot less. Therefore the benefits are that you can build something the same size and achieve the same strength overall but will weigh less. Ti also has other excellent properties like resistance to corrosion and fatigue as well as a high melting point. Great for bike frames, engine parts etc.

Since we're talking about freehubs which will be the same size (take up the same volume by design) if they are steel, titanium or peanut butter, the strength of the steel one will be higher. You would need to make a Ti hub much bigger to achieve the same strength as steel. Also, the toughness - resistance to impact - is lower than steel which is probably why the body on BIGA1's freehub is being compromised. I would imagine the cassette is steel.

I see the only advantage of Ti in a freehub as being weight reduction but this is so close to the rotational mass centre that it would make very little difference.

Hope that makes sense.

Depending on alloys, and the exact specificaltion of the material, Ti is a similar strength (in terms of tensile strength) to steel, but at a lighter wieght.

high grade steel if often a fair bit strogner than a Ti alloy, but obviously heavier.

Unless your trying to reduce weight, dont bother, the freehub body will still indent.
