I’ve had the Switch EVO hubs on crests for a few months, hubs are great so far, bear in mind they aren’t made by Superstar but Novatec who make things for lots of companies. Bearings are just bearings and cost a few quid from simplybearings to replace if they do go early, but just stop jet washing your hubs/drenching in muc off etc.
I would have to say the build quality from Superstar isn’t great, both my wheels came with vertical and horizontal wobbles out the box, and the rear detensioned a lot within a few rides with some spokes coming completely loose.
£100 less than Hope hoops though, so if you are able to true your own wheels still worth it imo.
