When I returned from my ride yesterday I noticed that there was play in the cassette (sideways movement). I removed the cassette and noticed that the cone shaped nut (held in place with a grub screw) had worked loose. I removed and cleaned everything but I don't know how tight I should do up the 'nut'. It is completely round so hand tight is all I can apply..is there a rule for how tight this should be?
I also noticed while checking the front wheel that 1 grub screw is missing, is it important I get a replacement...the QR holds everything tight. Are these a standard size?
