Sure, thats with everything. On a road bike you can get away with it for extended period of time between servicing, but for dirt/gravel, it’s a foolish move. Technically speaking, why you anyone choose the harder route having to unpack, clean the dirt and grime, re-greasing, and I eventually replacing scored ball bearings (from small rocks, etc) every few gravel rides when you could save yourself money, time and effort with sealed bearings? Sounds like a no-brainer to me.

PS. Besides, sealed hubs are relatively cheap (Formula, Novatech, Oigin8, etc) or as cheap as old school loose ball hubs, but in my experience, even the freshly re-packed loose ball hubs and bottom brackets I’ve assembled don’t spin like my used sealed hubs. Definitely no reason not to upgrade.

What has your experience been like with both?
