Oh, and I'd hardly call your hill climbing slow! I'm quite a bit slower than that.
Thanks for the compliment. I just get passed alot by others during these climbs that I must assume that I am the old slow guy.
Reason for the new makeup............I am buying a all carbon frame and doing a custom build myself and want to try and transition to a compact double. All the folks I have talked to said the compact is the newest thing to get you similar gearing to that of your triple compared to a std. double.
I want to force myself to get somewhat stronger. As long as I have the thrid ring I continue to use it in the 30-25 combo even when I don't need it. Not to mention I want to eliminate all those shifts. If I don't like it, well I can buy another triple and transition back or sell the custom built to someone who will benefit by it.
My current triple bike setup I am keeping for training rides since it will be slightly heavier.
Thanks for all the feedback. I will take everyone's advice and mold it into a build in the coming months.
