Review on MEGHNA Shimano RD M310 Mountain Derailleur by Joseph Swanson

My son's friend lost control and hit the rear derailleur on his Walmart mountain bike. It's amazing how much damage this has done (very cheap). Fortunately, no boys were injured. This switch looks much better and works great once adjusted. We will now replace the front derailleur with the same type as we were unable to adjust it properly. He must have been slightly bent. If the front Altus replacement is as good as the rear Altus, he should be very happy Tuesday!
