The common teeth of the rear flying should be close to the middle as far as possible, so that the speed can be up and down~~ Xc cross country, now many cars are flying behind 36T, so the ratio of teeth is less than 1:1. It is awesome for climbing, and it can also accelerate. Am & can also choose 36T&It's suitable for the riders cruising about 30 yards on the flat road, or the XC & players with better physical fitness, or those who want to cross-country with the expansion plate, but also want to be faster. I am the 36 T before and after myself 38T&They are more inclined to mountain horse players, cruising 32 + ~ ~ ~ & or with the expansion plate, the players in the competition
