    I love how people obsess over gearing on this forum. When I got my new bike 2 years ago, I went from a 53/39 with a 12-26 to a 50/34 with a 12-30, which I changed to a 12-26. Honestly, I spend 99% of my riding time on the big ring and never really think about it. I shifted the FD on the standard double a lot more (or at least I think I did). The only time I've felt limited by the compact was in a road race last weekend where we had extended downhill stretches with a tailwind. The field was stretched out and holding 45+ mph at times, and I felt that I could have used either more teeth in the front or an 11 in the back. It didn't matter too much, as I'm 175 lbs and most of the guys in my field were ~150 so I just tucked in and passed them as they pedaled while I coasted. Point being, a 50/34 works even in races, so long as you don't have a downhill sprint finish.

    90rpm is fast? Obviously the small ring isn't meant for extended use on easier terrain but the 36 makes it more useful for that purpose than 34. 39 is even better if a 39x27/28 is the lowest gear you'll ever need but in hilly places thats not low enough for most people

    Ha! Different (pedal) strokes for different folks I suppose.

    My 42/16t fixed gear has an 18t as well on the other side. I use the 42/18t for recovery rides the day after hard road, track or gym workouts.

    Yes, 90rpm at lighter loads starts feeling stupid high and I want to upshift. I'm not talking about a hard sprint type situation. Just cruising along on the small ring and I want a burst of acceleration to make a light. I don't want to hit the upshift button and realize I'm out of gears. I'm well acquainted with the climbing in SoCal and, since I like to spin up hills, I wouldn't want to go much, if any, lower than a 34/27 granny gear (or the equivalent gear inches.)

    You can always shift to the 12, even on my bike with short chainstays it works fine. Or run an 11-28. Like you said there is no perfect solution for all situations, just MO but 50/36 works better than the standard 50/34 for above average riders.

    Hi, so I'm a bit of a new comer when it comes to chain rings and cranks and cassettes. Can someone briefly explain some of the terms for me please? Thank you . (Yes I have tried google and haven't found much) .. Also, I had and idea of changing my 10 speed into something higher, maybe buy a 7 speed cassette with a 3 chain rings (Which is the reason why I want to know more about the crank area). Any suggestions?
