|FSA Carbon Pro Compact Crankset||glia|

|Has anyone tried this crankset and can give some feedback. I am currently using a standard Dura-Ace set with a 12-25 cog. I need a little lower gearing for all the hills around here. Rather than going to a 12-27, I came accross the "compact gearing". This is what Coloradocycling says about it:
The Full Speed Ahead compact gearing has many great cycling applications but has become popular among cyclists who want lower gearing but don't wish to use a triple crankset. Versus a triple, compact gearing offers lighter weight, lower Q-Factor and faster shifting. While the gearing is not as wide as that of most triples, it offers substantially lower gears than the typical double crankset while allowing the rider to have closer gear ratios on their rear cassette.
Gearing Example: Traditonal 53/39 with 12x25 cassette.
53x12=119.2 inch gear.
39x25=42.1 inch gear.
Compact: 50/34 with 11x23 Cassette.
50x11=122.7 inch gear.
34x23=39.9 inch gear.

|If that is your only motivation for changing things, change the cassette. It is cheaper, easier, and a quicker change than changing your crankset.

|A 38T inner chainring may be worth considering. 38T is the lowest you can go for a 130mm BCD as found on the Dura Ace crankset.|

|check with a gear calculator like the one at Sheldon's site. the difference between a 38 and a 39 is negligible.|

|I just put this crankset on my bike, ISIS drive, FSA Platinum pro Ti BB. Quite stiff, looks nice, lighter thatn most any double except Record Carbon (and less than half the price). I have a DA 12/27 (my hills are steeper or my legs are weaker, take you pick) and use Ultegra shifters and standard double FD. Shifts fine. No significant difference between granny gears that I can tell(30/25 on my triple, 34/27 on the compact drive). Nearly 200 gms lighter. I am happy with it. Chain line is better than on my triple. I can use the whole cassette with the 34, and in a pinch with the 50, but I try to avoid the 50/27 and 50/25 combination.|

|Just received mine. They shipped the ISIS instead of Octalink, so I may switch it, need to see what an ISIS BB and tool will cost me. But, a very nice crankset. I got mine for a century I have coming up, Six Gap in GA. There is 10,700 feet of climbing, and although I have done it with a 39/27 gear before, it was not pretty. I am really looking forward to the 34/27 low gear.

|So far it appears that I get more usable gears, plus I find the 50 tooth chainring to suite me fine since I really don't push the higher gears in the flats as I did in my youth. I had already switched to a 52 tooth. The compact seems to be a nice compromise between a triple and a standard double crank. If you're worried, I believe a 11/50 will give you a higher gear by a bit than a 12/52. I haven't been bothered with running out of gears on long descents yet.|

|After posting this question a week ago and not hearing any negatives I went ahead and ordered mine and have been riding it for about 150miles. I must say that the gearing makes a lot of sense. I actually left my Shimano 12/25 cog in and shortened the chain. This gives me three extra gears on the low end with the 34/50 as compared to a standard 39/53. I am only loosing the hardest gear, which I really do not need in our terrain. Of course it is a sharp looking crank and appears to be well build. For those of you who have lot of hills in your back yard and like to climb sitting, this is the way to go. The weight savings total up to almost 100g as compared to a Dura-Ace once you factor the weight savings on your chain. You need to take out several links to fit it properly. All in all a good compromise.|| |
