aluminium rear sprocket - how long of life span, weight vs steel?

[mvalenti]

You may want to research that one. Titanium is way more expensive than that sprocket sells for. A lifetime warranty.....biggest line of BS in existence. What happens if the company goes under in a couple of years?

I looked at their stuff a few weeks back when doing the sprocket/chain research.

The BS story on their website should get your spider senses tingling.....

Just google " Krause racing chain" and there is more!

(rubs eye) but it was posted on the internet.... everything is true on the internet right? Or have I been lead down the wrong path?

my machinist buddy said that for him, buying raw titanium stock isn't really all that expensive surprisingly. maybe it's harder to work with or something which drives up the cost?

titanium isn't three times harder that Stainless steel, is it?
I've worked with it a little, it didn't seem THAT hard.
