NSMB Rider says:

40PSI? seems so high

Ian Wassink says:

Can you do a similar video, but in more detail starting with frame only? I suggest something like the Dream Build videos that Gee Milner does on YouTube, but with your insightful commentary from bottom bracket and headset assembly on up. Maybe you don’t need a brand new bike to unbox, so perhaps strip one of your DBs and do a massive service at the same time?

Why don’t you use a sealant injector? It’s easier and cleaner.
