I currently have a Campagnolo 10 speed 39-53 (front) compact double with a 12-23 (rear). I am considering having my front crank swapped out with a 30-42-53 triple (front), maybe this one: http://www.niagaracycle.com/product_...ucts_id=405909

This would be done strictly to help me out on some of the hills I am trying to conquer. I have gone to the Sheldon site and plugged in the numbers for gearing. But, I don't understand the information.

Is there an easy answer as to whether I'd be gaining that much more in lower gearing? Would I easily notice it riding uphill or would it be more subtle?
