Finally a video that brings the mystery of preload to the YouTube community who actually explains how to do it in simple concise procedures

Thankfully this allowed me to understand proper crank installation on my new build. I was starting to think I bought the wrong size spindle, in spite of "all the standards matching."

Thanks for the tip. It helped me a lot when installing a rotor crank. Greetings from Germany (Oldenburg)

Thank you! So many videos completely skip this part and I had no idea why I had play in my cranks!

That’s why I love Shimano XTR, so easy and fast to install and remove, a true racing product

Thanks, this is my first time building a mtb bike, last bike I bought was the Gary fisher rig in 2011, Im not impressed with the MTB industry and the technical support is seriously lacking.

Thanks for watching? Thanks for making this video!

I found out that there are two variants of preload adjuster. Yours tighten if rotated clockwise. There is another variant which tightens if rotated counter-clockwise like on my 2015 Stumpjumper FSR Comp. Anyhow, just follow the direction of the + arrow and you are always good to go.

That was clearer than sram's version

Great clear instructional video, respect. All the best Andy

Best to bin the plastic Sram preload ring and go with the Cane Creek aluminium version for durability

Cheers Calvin helped me out enormously !

Bearing preload is per design meant to push the bearing balls into the conical races for proper (smooth) operation of the bearing. Somehow the bike industry has hijacked the concept to simultaneously take up lateral play from poorly built parts (high manufacturing tolerances), so people generally follow the advice in this video to use the preload collar to adjust for only lateral play. This is probably ok for many cases, but as there doesn't seem a way to quantify preload force with these collars, I'm wondering how many times you're left with subpar performance due to insufficient or excessive preload
