Other than putting it on a race bike, I fail to see the point of an aluminum sprocket other than draining your wallet faster.

It's like titanium lug nuts or carbon fibre trunk lids or any of that other crap that people buy because it saves them 0.002 ounces of weight and will reduce 0-60 times by 1/100000th of a second

I ordered one of those last week - should come in soon. It's the only brand that makes a 45 tooth (stock size) sprocket for my bike in stock (525) chain pitch. We'll see how it holds up...

+1

If you can get a steel sprocket for your bike, I'd get that. The weight savings (by going with an aluminum sprocket) are going to be minimal and not noticeable (IMO).

Hard anodized aluminum should hold up pretty well when compared to steel.

Stay away from Vortex sprockets - they'll melt like butter.

On the other hand, if one spends enough money to lose a kilo or more of unsprung weight off one wheel assembly - much of it rotating - one might easily feel the difference. Its the sum of the individual weight reductions which make a difference.

As far as aluminum versus steel sprocket...if you opt for aluminum make sure its hard anodized and that you lube your chain religiously otherwise, like someone has already pointed out, it may melt like butter. The aluminum/steel combination seems like a nice alternative.
