100% right lads chain slack is the most important thing you can do, I check mine on all my bikes after every ride (normally 200 mile ride each ride out no less tan 100) and use worth dry chain lube after every ride. I also have a small laser chain liner tool you put on the sprocket to check it's 100 % straight, ( only �45) very handy. After reading your comments on the poly rubbers, will be interesting to see how they feel when I get out on it next week. Have a good weekend lads and ride safe.
