John:

I do have a compact crank and a 12-32 cassette based on a SRAM cassette except that I replaced some of the lower gears with different/lighter Shimano cogs (closer gearing in the middle where I currently ride the most).

The truth is that I just started riding two years ago and am still getting into shape. I also never knew about slow twitch vs fast twitch muscle fibers, but I was a basketball and baseball player in high school so I was basically fast twitch fibre person the first 60 years of my life.? and that's the story I'm sticking to.

But it is still impressive to hear about others rides.

Lynn, on the other hand, run's an 11-25 cassette and non-compact crank and does just fine.? Have to admire the aerobic base of former triathloners.
