Carbon or aluminum steerer on carbon fork?

I'm building up a new road bike.
What's the general consensus between a carbon or aluminum steerer?

I'm looking for light weight but not necessarily a weight weenie.
Primarily looking for comfort from road chatter with the carbon fork.

Any benefit of a carbon steerer other than weight savings?
Aluminum more 'practical' from a strength / durability factor?

Thanks,
Steve

I like aluminum steerers. I am 215Ibs.

If I were racing, then maybe I can consider carbon steerers, but at my weight, and a non-racer, aluminum will do, thank you.

You will get that comfort with AL steerers and carbon legs. Steerer material only matters if you fear replacement costs.

I've got all-carbon forks and forks with carbon blades and Cr-Mo steerers. Except for the weight (and cost), I can't feel any ride or handling differences.

I think the real consideration is weight and there is a significant difference in weight. I think the carbon steerers are worth the extra cost. Just be very careful to not over torque the stem bolts, 5 nm max on the pinch bolts and that's probably more than necessary.

That's very true. My Kestrel EMS Pro carbon blade/Cr-Mo steerer fork weighs 495 grams and my Easton EC90SLX all carbon fork weighs 295 grams both cut for 57 cm frames. These are real, not advertised, weighs as I have a lab quality gram scale available.

Now how important that weight reduction is to the OP is his call. The Easton was much more costly than the Kestrel.

Any BIG concern about failure of a carbon steerer?
Obviously, do not over tighten as mentioned.
I'm pretty competent with a wrench.

As I recall, you're not actually gonna be better off with an Al or Fe steerer, b/c there's as much a chance of the interface where the carbon is bonded with the metal failing as there is with the carbon steerer failing. If i were you, I'd get your favorite fork, and not worry about failure too much; just remember, you won't get the same service life out of carbon as you would from, say, an all-steel fork.
