Giant P-XC2 hubs

[hihello]

Hi hubbers

 

Semi-rooki mtber here, I'd just like to know if anyone can tell me if the Giant P-XC2 29er wheelset comes with Sealed bearing hubs? Are sealed hubs the way forward or is it a personal preference type of decision as I am needing to replace my wheelset and I know little about what I am needing to look for?

 

Thanks for the help
