I installed it in MTB where a child rides. I thought that if the hem of the trousers could reduce the rubbing on the chain, I thought it was a purchase. For general-purpose goods, mounting angle etc. are slightly misaligned like product photo. I think that it is even better if you can adjust the angle or if you can review the angle. However, it will function sufficiently even in the present situation. The installation work itself was also simple, and it was made into soup. However, since the metal band wrapped around the frame is thin, the edge is unprocessed and sharp, so I cut my finger. Care is required when bending or position adjustment in the installation process.
