There is a particularly steep hill I want to assault this year, and a 34-34 would sure make it much more possible to defeat.
Sorry for the late reply.....
My bike group – Shimano 5600 105 10speed, 5600 105 front derailleur, FSA Gossamer 50x34 compact.
Added these components for wider ranged gearing;
Rear derailleur – Shimano Deore XT M771 SGS long cage
Cassette – Shimano Deore XT 10-speed SH-CSM771 11-34
Chain – Shimano Ultegra
This gearing really works for me, even wider spacing between the middle cogs. Where the 12-25 had me frequently shifting up or down twice, usually one shift will have me in the right gears. Some of this is because
I tolerate a wider range in cadence. Usually between 80 to 90, even 70 to 100 I'll manage OK.
The shifting is smooth and silent, never misses when properly adjusted. I've only had to make small adjustments due to cable stretch.
