During installation, it is necessary to adjust the angle to ensure that the front and rear wheels are in a straight line. If the angle is not correct, it can be adjusted by adding or removing shims under the mounting plate at the axle position. If the front and rear wheels are not in a straight line, the chain will tilt to one side. This causes the force to tilt to one side all the time when the flywheel rotates, making it easy for the flywheel to be damaged. France, Germany, spain, Italy. Feedback is very important to us.
