My bike came with a tubus cargo classic. No complaints here. Solid and sturdy and ive exceeded the weight limit plenty of times with no issues. The only thing to be mindful of: if you use the standard type rackpack, ie the narrow one and not the ortlieb duffel, mounting panniers blocks off any easy access to the top of the rack, I have to strap my rackpack down with ratchet straps, luckily the altura dryline packs have plenty of spots to thread the straps through. If you use the narrow rackpacks and cant strap through them then go with something with seperate side mounts from the top bars like the logo’s and grand tour
