This is favored by many triathletes as the perception is that it "saves" the legs for the run, but your gearing is determined by the rear cassette. For example, a 53x18 (53 front, 18 in the rear) is basically the same gear inches as a 50x17. | |

| May 14, 2013 at 12:34 | comment | added | Kibbee | Probably worth noting that the number of gears on the cassette (in the back) won't do much to determine the "range" of gearing, but really determines the size of steps between individual gears. I have an 8 speed (11-32) with way more range than most racing bikes, but the gears are further apart so I sometimes feel like I can't get in the right gear. It's likely that an old 14 speed bike will have just as much range as a modern 20 or 22 speed racing bike, but the steps between the different gears will be much larger. | |
