Tooth number selection------------------------------------------------->
The number of teeth is suitable for people (take 26 inch wheel group as an example)
- 32T&The common BCD 104 crank can be equipped with small teeth (except for Fuliye's 30 tooth structure), which is suitable for the places with steep slope, XC & nbsp; cross-country (without expansion disc) or AMFR DH heavy-duty vehicle. Or middle-aged and elderly riders don't pursue speed.
- 34T Commonly used teeth number! (Take the 26-inch wheel set as an example)
- Most riders are more than 20 cruisers, with two gears in the front and seven or eight in the back. I'll ask if you want to speed up a little bit. If I want to, I will push 36t, if not, I will recommend 34T. There are two reasons why it is not 32. 1. In order to leave some space for the high-speed riders, 2. 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 & nbsp; can also choose
- 36T&It's suitable for the riders cruising about 30 yards on the flat road, or the XC & nbsp; 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 + ~ ~ ~ & nbsp; or with the expansion plate, the players in the competition
