Want to change the butterfly, but the transmission is to turn, and will not demolition, seeking master enlighten me, but from the take down to the new to the other, will not affect the performance of the transmission? More
Performance will certainly not affect, but can not be set in the butterfly is a problem, because the butterfly to turn a few bends, it is estimated that the switch does not go into the installation.
On the demolition, you have to do two things: 1. Loosen the handle: turn the left and right ends, near the end of the stand (that is, inside), usually a circle, around the circle to find, there is a hex The screw, usually 3 mm to 4 mm between. Can not find, put the handle of the handle a little lift up, certainly have .2. To solve the turn to pull out the horizontal, the speed line is not long enough: Off, put the vertical and the bike is connected to the pole .----------- demolition time, do not pull hard, to comply with the pull. The speed line and the brake line as far as possible not to fold This is negligible .------- Installation order: 1. If you put the vertical and the installation is not covered, is set into the need to put the first set into the horizontal 2 . Install the handle 3 Install the brake lever 4 Hold the stand to the bicycle 5 Keep the vertical and the horizontal between the fixed .-------- Adjust the angle of thinking: According to ergonomics, the angle of the brake handle is: sitting Riding on the bike, holding the handlebar, the hand and arm is a line.Therefore, usually the brake to the front 20 to 30 degrees below (according to personal height, front, cushion different, no standard, as long as a Line can be)
First remove the screws above it, and then attached to the line together down the line. To be energetic. Should have no effect, butterfly put the same.
