I dern near spun my legs off today. I went on the 3rd ride on my new/old fixie today and went down a hill that I've gone down before many a time on my old fixie. I hit 38.6 mph and my legs [email protected] near spun off. My older bike had 27 x1 3/8 tires and 165 mm cranks. The new one is 700cx28 and 175 cm cranks. 10cm really DOES make a difference!

I should think it would make a difference!

You must have some legs to spin those 175 cm cranks. Why, that's more than 5 1/2 feet in American units!

my question is this...what dern gearing are you using and do you ever go UP that hill? maybe this is knee jerk and not well thought out, but spinning down at 38 mph seem that going up would be a b!tch....

42x17. My legs were spinning REALLY fast. And yes, going up IS a b*tch. However, it's kind of unavoidable where I live.

Your gearing is about what most fixers choose for varied terrain: 66 inches. You were indeed spinning really fast, about 197 rpm if I calculated it right. I run a 75-inch gear and I think the fastest I've done is about 33 mph -- just under 150 rpm (going up is a b*tch). So yeah, you were spinning.

So how exactly DOES the 10mm make a difference? Was it noticeably harder, or weirder, to spin the longer cranks at those high speeds?

I really noticed it on descents. That, by far, was the worst. It seemed that I was able to climb better. More leverage, I suspect. Both fixies that I've had were geared the same.
