Cycling to effort , we must know the right speed skills , use of variable speed gear ratio , in addition to help regulate energy, so cycling easier and prevent the movement of the knee joint or injuries . Many beginners and even for some time the riders ride , or not quite sure what kind of opportunity in which to change gear for use .Monton cycling wholesales |
Mountain bike transmission is divided into two parts , the left hand controls the front tape , right after the flywheel control , usually by " after the main front , supplemented by" way to adjust . Stampede gear ratio than struggling with heavy foot or high-speed file called , is to save time and effort , suitable for flat road acceleration or downhill ; stampede is more labor-saving light gear ratio , is to overcome the climbing of the weapon. With the terrain , slope and speed of change , we need to regulate the use of physical transmission system , how to use , you must first understand the bicycle speed chainring match. bicycle helmets
General MTB front chainring standard with 3 type, number of teeth is common 42,32,22 . Note 3,2,1 file ; vehicles after the flywheel is used by 7 to 10 ( with money chainring 3 is 21 to 30 variable speed ) , the number of teeth ranging from 11 to 34 , the number of files located in the front teeth Instead dish up teeth as a file.
Remember: before contracting with the use of the chain to try to avoid too large angle ( eg money, three money one after one or after 10 ) , such a situation is likely to cause wear of the drive system , so the 30-segment gear shift system , in In fact not all be used. The most important thing when shifting to keep pedaling rotation , remember the leg muscles softly, shifting the chain , the strength of the multi- drive systems caused serious depletion of the General Assembly .
Shift timing : this part is very important. Parking started: with pot gear ratio will cause the steering wheel from side to side , right knee , the transmission system is not good, so before stopping best to adjust speed , gear ratio to use light more effort to start smoothly , in general , shifting all the money in the middle chainring tune , is the best starting gear , if uphill start , gear ratio can not be too light , or may cause , " Alice wheelie " situation .
Smooth road between : After the start , the riders can be as personal strength, endurance , and good and bad road conditions , at any time in the transmission to control the travel speed , more healthy way of riding with the heartbeat table to maintain a certain stampede slew rate , unsteadiness the traveling speed of the body will get tired easily .
On the downhill : for when I saw the front shifting terrain changes there should be psychologically prepared , especially before the first climbing sections into the appropriate gear for good , do not move when riding at about the shift , so that the transmission system losses large, it is difficult to control the direction of the steering wheel . See front downhill onto the ramp first gear ratio would jump to high segment , low gear ratio makes coasting downhill riders remaining years Caikong phenomena are very easy suited wrestling .
Better transmission are likely to just jump files . The front of the control technology is the last word !
