Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

FSA SL-K Light or Dura-Ace crankset

These are about the same price (FSA is $100 cheaper including the BB),
which one would you get?

Dura Ace, no question. Do a search on the internet on issues with FSA cranks.

This. More specifically, issues with their horrendous and proprietary bottom brackets.

It must be hit an miss. My step dad has around 6000 miles on his SL-K setup with no issues. I've ridden on it and it seems nice

it seems like FSA crankset experiences are one extreme or the other. the dura-ace crankset is ugly but you can be confident it will perform well.

Agreed. Dura-Ace, you won't regret it in the long run.

Dura Ace, rings last longer and shift better. YMMV

Because it does not flex like the FSA. They are ok for my track bike but that's it.

You ride a road crank on your track bike?

I was referring to chain rings. That is where the not so precise shifting comes from.

I'm a bit confuzed. Are you saying the DA rings do not give precise shifting?

I don't think anyone would say that. FSA rings are as stiff nor do they have the ramp profiles of DA. DA is the gold standard for front shifting. I have never missed a front shift with DA DI2 even shifting ring and cassette at the same time.

OK, that's exactly what I think of DA rings also. I have always had problems with FAS rings.

You can't go wrong with either.

If the $100 means anything to you, the FSA are just fine. I have a 5 year old FSA SLKLight that still shifts like new. My Ultegra 6800.....not so much.

My FSA certainly looks cooler but is harder to keep clean. I can't say DA doesn't look good though cuz I like the look of those too. (apples/oranges)

Lastly.......I've worked incessantly (I have a very old, long-winded BB thread in here somewhere) on making BB30/PF30 silent. It's almost impossible but......

Wheels Mfg BB with the FSA's is close to perfect

Praxis Works with Shimano is 99.99% perfect

(Unless it's on a newer bike & there are no offerings for those.....I just hate using individual "cups" with ANY crankset as it's a non-concentric solution that is no-bueno, imho.

Consider Easton’s EC90 SL carbon crank. It’s lighter and stiffer than Dura Ace and looks beautiful.

I own and ride both. (The FSA SL-K Light because Dura Ace doesn't offer the gravel gearing I was looking for.) Mark me down as another vote for Dura Ace. The shifting is much quieter and more reliable. If cost is the determining factor, go with a Shimano Ultegra crank. It's a lot less expensive but performs the same as the Dura Ace.

Dura Ace.

The only thing that made my SRAM front shifting performance improve was when I put Shimano chainrings on the crank.

And Ultegra front shifting was revelatory compared to any FSA or SRAM offerings.

Not to disrupt the conversation, but the original post was made in 2012. Hopefully he's chosen by now.
