Re: Hi, I'm new
Now I am scared of the machine. This evening I took a ride, after adjusting the chain tensioner. I rode maybe a mile out and was returning home when the chain broke! Didn't come apart at the place the link can be removed either. The reason I am afraid is that I was riding at some speed, probably 25 or more at times and in traffic. Fortunately, I felt and heard that something was wrong and stopped. By then the chain was off and wound around the back sprocket. If the broken chain had thrown me into a car it would have been curtains. The last message was from stude13 with the suggestion to throw the tensioner away and get a #41. I don't understand what you mean.
Grinding the teeth on the sprocket I understand and that sounds like a good idea.
