But I can only find them for $56 each, which is getting close to the cost of the crankset for two rings.
And yes, the drivetrain is "relatively" quiet - I do admit that I'm being a bit of a perfectionist with this chainline change. Things are just a little too cross-chained in the big-big gear combos, so I'm looking to optimize things if possible.
First, will that FSA even take a 30T chainring? If the bolt circle is 110mm, the smallest chainring that will fit is 33T and 34T is far more common.
Second, that's a lot of trouble to go to to reduce cross chaining in a gear that shouldn't be used.
