re: easier on the gear box
I'd be interested in reading that post. Got a link?
A CSS is cheap, can be changed in minutes, can be used with the oem-length chain (108L), has no effect on the rear chain guide.
A rear sprocket is NOT cheap, cannot be changed quickly, cannot be used with a 108L chain (in the 50-51 sizes and maybe even with a 48 depending on the condition of your chain), may require a different chain guide.
re: shift more
Or..shift less. With a lower final drive ratio (higher numbers math-wise), I find I shift less not more. I'm more likely to be in 2nd gear than ever being in 1st. 2nd gives me plenty of oomph with a 12/47 combo that I wouldn't have with a 13/47. So, with the oem gearset, I'd be in 1st gear..and be shifting more.
You say po-tay-toes, I say po-tah-toes.
