Update - Double chainring -yikes

[violette]

FYI: There are compact cranksets with carbon crankarms. I have one, FSA's SL-K compact. They are available. Did the shop just not want to order one for you?

In terms of gear inches, there isn't much difference between a 34 chainring and a 27 cog (road setup) and a 39 chainring and 32 cog (road/mtn setup): 33 vs. 32 gear inches. One big difference between the two set-ups is the weight, however, which may more than negate the slight gearing advantage the road/mtn setup has.

Two LBS called FSA and they don't have them. He said something about I have a 9 spd 130mm and now they make 110mm 10 spd.

Standard cranksets use a 130mm bolt circle diameter. The smallest chainring possible is 38 teeth.

Compact cranksets use a 110mm BCD, which allows a smallest chainring of 34 teeth.

FSA advertises their cranksets as 9/10 speed compatible.

If you're happy with your set-up now, I wouldn't worry about it.

Now I'm curious about what they did put on your bike the first time they swapped things....
