Problems solved by technology

[0003] However, it is not enough for the guide wheel and the flywheel to be close together. If the guide wheel is too close to the flywheel, the chain will be excessively squeezed, resulting in unsmooth rotation, noise and other undesirable phenomena.
However, nowadays, adjusting the distance between the guide wheel and the flywheel depends entirely on the feeling and experience of the rider, so inexperienced riders have no basis for adjustment, resulting in poor adjustment

Abstract

The present invention relates to a tool for adjusting the position of a rear shift guide wheel, which is used in a rear shift system. The rear shift system includes a plurality of flywheels and a rear derailleur. The rear derailleur includes a guide wheel. The position of the rear derailleur guide wheel is adjusted The tool is used to assist the user to adjust the distance between the guide wheel and the flywheel. The tool for adjusting the position of the rear shifting guide wheel provided by the present invention can provide an adjustment reference, so that the rider can accurately adjust the distance between the guide wheel and the flywheel, and then achieve a better shifting speed.

Description

technical field [0001] The invention relates to a calibration tool for bicycles, in particular to a tool for adjusting the position of a rear shift guide wheel. Background technique [0002] After the rear derailleur is assembled on the bicycle, it needs to undergo various corrections to fully cooperate with the surrounding components, such as flywheels, chains, etc., to achieve the most suitable state of use. Therefore, the adjustment structure of the rear derailleur is designed with low-position adjustment screws, high-position adjustment screws, fine-tuning knobs for shifting cable tension, tension adjustment screws, etc., for the rider to adjust. Among them, the tension adjustment screw is used to adjust the distance between the guide wheel and the flywheel, and then can control the speed of shifting. The closer the distance, the faster the shifting speed. [0003] However, it is not enough for the guide wheel and the flywheel to be close together. If the guide wheel is...
