Price Paid:  $280.00 at eBay

Favorite Ride:
Central TX Hill Country

Bike Setup:
Custom Spectrum Steel road with DA 10
Cervelo P2C TT with DA 10

Summary:
So, this was the first 10 speed component I upgraded on my existing all Dura Ace 9 speed bike. And I didn't really get it for performance reasons, only because my existing crank looked like crap from corrosion.

But the minute after I bolted it on and took it for a test ride, I knew that this crank was about more than looks. It was SOLID like a rock under me and front derailleur rubbing is a thing of the past. On hill, mashing, whatever, this crank is there like the earth under your feet. The rings shift great too.

This is by far the best component of the DA 10 group. I ended up buying one for my Cervelo also.

Strengths:
Stiff, no flex, rigid, solid. Looks great too. Shifts well. Easy to install and pretty light.

Weaknesses:
I don't like the fact that the mounting bolts are open to be sweated on.

Bike Setup:

Summary:
Amazing crankset for sure, and worth every penny. I was considering going SRAM (less expensive as well), but wanted something was proven on a road bike without any possible kinks (SRAM good brand, but newer to road bikes). That's what Shimano in my opinion will bring to the table - it's bulletproof like that. If you get this crank, be sure to just get the whole gruppo. Crank is great, but nothing compared to having the whole orchestra working in harmony...:)

Strengths:
Light, Good power to wheels, Rock Solid Construction, Looks like something you'd find a Silver Shop (slick looking)...

Weaknesses:
None yet. But definitely consider SRAM in the future too, heard very very good thing about that gruppo - a real player.

Summary:
I switched from my stock FSA SLK double compact carbon crank that came with my bike...I also switched to a Dura Ace cassette, front derailleur, and chain...I already had a DA rear derailleur on the bike...the performance of this drivetrain has been amazing...smooth...I feel as though all my effort is transmitted into the bike...a great upgrade.

Bike Setup:
Bianchi 928, Dura-ace Cranks, derailleurs, chain, and cassette. Ultegra shifters and brakes. Fizik saddle and bar tape. Thomson seatpost and stem. Mavic Ksyrium Elites. FSA K-wing bars.

Summary:
I upgraded from the stock FSA compact that my bike came with and it was the best move I have made. Paired with the Dura-ace front and rear derailleur and a Dura-ace chain and cassette it is the smooth running and effortless shifting. If you are thinking about one, buy it, buy today, buy it now!!! I will give up some things in life but this is not one of them. Ride one and shift back and forth on the chainrings and tell me that is not perfection....

Strengths:
Pure shifting bliss
Light weight
No flex
QUALITY QUALITY QUALITY
And it just looks soooo cool!!!!

Weaknesses:
ZERO-NONE-ZILCH-NADA-get the point!

when I can

Bike Setup:
TREK, SEE FSA Slk carbon review,

Summary:
WOW, what a difference top of the line cranks can make. Had problems with the FSA SL-k carbon cranks, Dura-Ace are light strong easy to install, took me less than 10 minutes, and Im no bike mechanic. Couldnt wait to go riding, just the weight difference is noticeable from the FSA's . Shifting is precise and acurate every time. Just in the way these feel compared to the FSA's, make you feel like your going faster, and climbing quiker.

Strengths:
Great cranks, If you own FSA's you owe it to your self to upgrade to and awsome crank set. you wont be sorry..

Weaknesses:
None
