I've never had an issue with press fit bb, on any of the road or mountain bikes I've had. The trek I use for winter has around 7k on the original bb and still runs smooth, and I ride in all weathers, I guess I've been lucky.
Not if you have to do it twice a year. Also note creaks aren't always curable by reassembly and replacement. It's a very impractical standard. Personally I can live with on my dry weather Sunday best road bike. But all my other bikes have threaded bbs.
Swapping out bb86 doesn't look too bad if you've got the correct tools.
Because press fit doesn't work like that. You "pop" the entire bottom bracket out and then have to clean the shell and put a new bottom bracket in.
Yeaaaah. Finally some proper deals. Proper eye candy 🤤
