Wondering if someone could help me , I’m having some issues with my chain , I tightened it the other day , then on the way home it came off the rear sprocket , didn’t snap. today I’ve taken my wheel off, put the chain back on , tightened the chain , went for a quick ride about a mile , when I checked th chain it’s completly slack again ? Doing my tree in . Any ideas ?
You probably need a new chain, also it need's to be correctly adjusted and in-line with the front sprocket !
