What Northwind says. I’ve had a pair of Switch hubs / Spank rims for a few years now, and I think they’ve needed truing twice – but I’ve never had a pair of wheels I’ve not had to true, mainly ‘cos I have a habit of blatting down rocky stuff and getting pinch flats. Hubs are great, I don’t think I’ve ever changed the bearings though I did need to tighten them a touch once.
On the flipside, a mate had a set of their DH wheels which were build spectacularly badly. He is a big lad, and he was riding in the Alps, but he’s also a mincer and they started pinging spokes on the first descent.
I’d buy another pair.
