| Jan 23, 2014 at 18:10 | comment | added | R. Chung | I'm slightly confused by your question. You mean for the same size chain rings, like 52-tooth or 39-tooth? Or do you mean a 34-tooth chain ring on a 110 BCD crank vs. a 39-tooth ring on a 130 BCD crank but with corresponding differences in the rear cogs so that the overall gear ratio is held constant? What is the comparison you're trying to make? (BTW, for the same power input and cadence at the crank, force on the chain ring is inversely proportional to the number of teeth on the chain ring, so a 34-tooth chain ring carries 39/34 = 1.15 ==> 15% more force than a 39-tooth ring.) | |
