Update:
I just checked the website and it doesn't look like you can get to a 34 chain ring on a standard (130mm) crank. However, if you go with a compact (110MM) you can put a 53 or larger chain ring on it. So, the compact has the advantage.
Thanks for the info. I've been looking on CL and ebay for a few weeks. I've seen the chainrings for sale, but I think might as well get the whole set, so I can sell the standard.
Is 12-28, the biggest you can go on Shimano 53/39? I believe so, from the threads I've skimmed. Then, I think I've seen some people run a Sram cassette?

I will say, I've never really used on 53x11 other than to test it out. There just hasn't been that kind of terrain here where I can just fly on that gearing. What is the top speed of that gearing before you spin out? 45-50 mph?
I have been on the 39x25 quite a few times.
