Road bike cassette ratio. Road bike cassettes will have smaller sprockets with a smaller jump between the teeth sizes when compared to mountain bike cassettes. My last bike was campag equipped it had a 53 39 crankset with an 12 25 cassette 9 speed i think. 3 is green 2 3 blue and below 2 red. Most road bikes will come with 11 12 or 13 teeth on the smallest sprocket and then will have anywhere between 21 and 32 teeth on the largest sprocket.

Most road bike cassettes have an 11 12 or 13 tooth smallest sprocket then between 21 and 32 teeth on the largest sprocket. If the chainset puts you in roughly the right range the cassette narrows down the ratio so you can maintain the ideal cadence. If you were on the flat or gentle gradients either up or down the ratios of the cassette were quite close so there weren t big jumps making it easy to find the right gear to be in. Road bike cassettes for climbing.

Every road cyclist understands that size of the chainrings and sprockets dictate the gearing of the bike however there is more to the concept than simply the number of teeth involved.
