I would say no. I’m a long time UST user, and in a moment of foolishness decided to get a rear wheel built on a DT ex500, with the rim strip, just because I had a 36 hole hub lying about. Terrible experience – it’s very tough to mount the tyres (taking them off is actually toughest), but you do actually get good at this after breaking 8 tyre levers.
Seating the tyre is the big problem – it was life and death with a track pump, thought I was going to have a coronary. I’m talking about UST tyres that my kid sister could put on an 819.
On the plus side, I now understand why some people have such a hard time with tubeless. Something that was always impenetrable to me using UST.
Built 819s are going for bargain prices on the bay at the moment it seems, just bought and sold a couple. Don’t know if it’s with winter coming or what.
