Continental GP Tire Model?

Bought these conti tires from an auction near me. They were labeled as “GP5000 S TR 28mm” and came in a matching box, but the sidewall only says “Grand Prix”. Just want confirmation on the exact model so I can be sure i’m able to run them tubeless in the future. Been riding them with inner tubes for a week and they feel great.

Help With Drivetrain Incompatibility

I bought this used 2020 Giant Revolt 1 with a swapped drivetrain (From Tiagra 2x11 to Sunrace MX 1x10) off marketplace and it was shifting great during the meetup, but after a couple rides the shifting slowly degraded. So much so that I dropped it off at a bike shop to have them look at it.

A day later, they call me and say that they can’t work on the bike since the rear derailleur (sunrace MX mtb derailleur) wasn’t meant to be paired with Shimano Tiagra Shifters. For context, this is my first time buying a used bike and I had no idea parts like these had to match.

Im just a little confused since it was shifting great a week ago. I just wanna know what you guys think and if there’s a workaround around this or if i’ve just been screwed into buying a bad bike. One last thing, the previous owner gave me the original parts (third pic) if I ever wanted to change it back. Any insight helps, thanks.

Problem With Bike Shifting

Rode my gravel bike really hard through a paved trail and It’s shifting weird. Shifts are delayed and cranks make that clanking noise in the vid during gear switches (0:20 seconds). It's like the chain “snaps” to change gears instead of shifting smoothly. mostly happens when I shift up to higher gears.

Already tried relubing the chain and derailleur. Might just be a worn chain or casette but wanna know your guys’ thoughts.

Herman Miller Mirra from Marketplace, Worth it for 120?

Just wanted to ask if this damaged Mirra was worth it for 120$. It has a tear in the seat which does look concerning. Looking to pick it up by tomorrow. Any thoughts?
