Tech Talks Presented by Park Tool is a monthly video series hosted by Park Tool's own wrench whisperer, Calvin Jones. The series covers the A to Zs of some of the most prevalent repair jobs, with the thirteenth episode taking a closer look at annoying cassette rattle.
If you listen closely, you'll discover that our bikes can actually tell us when something isn't right with them. Having a discerning ear is important when tracking down those noises, and Calvin is here to show us how to recognize a common cause of annoying rattles.

Can you do a techtalk on bedding in Brake Pads??!!
There is lots of confusion, and everybody seems to do stuff differently, It would be great to see what they would recommend.
Tangentially, It would also be great to hear their advice for issues that arise, like cooked pads, cooked rotors, contamination etc. I think this is one topic that everybody should know more about, and i would like to see their recommendations. Its one of the few areas that truly drive me bonkers when my brakes are making noise they shouldnt.
But really you should be using the derailleurs High and Low limit screws to prevent the chain from dropping off either side.
A properly adjusted High limit screw will stop the chain from dropping off the smallest cog. A properly adjusted Low limit screw will stop the chain from dropping off the largest cog.

- try winding the lower limit screw in until it fails to drop cleanly into the bottom gear, then back off a fraction.
- check chain length, allowing for suspension chain growth
- you can add chain tension by winding in the b tension screw. It may slow shifting a fraction but can help keep a things tighter ones that need the chain length.
- you can adjust clutch tension on the mech.
