A couple of questions here.
One of Procore (and systems like that) USP's is that it squeezes the tire against the side of the rim and thereby prevents burping even when running very low pressure in the tire.
How does Huck Norris address this issue?
As your FAQ says:
"Q: For how long will I be able to use one?
A: It depends how low tyre pressures you run. Average user can expect that Huck Norris needs replacing once or twice during the season. This being the case if you run just little lower pressures than you use without Huck Norris. If you want to maximise the grip and run very low pressures so that tyres frequently bottom hard and cells in Huck Norris break open on those impacts, it will last you just couple of full days riding, but will save it’s cost in broken tyres. We usually replace ours after 2 long weekends of Enduro racing and practicing."
This means that quite soon one will reach the same cost as Procore.
What are the benefits of Huck Norris that compensate for the higher cost?

Thanks for the questions Michael!
1. Huck Norris does not prevent burping the same way as Procore or Deaneasy does, it doesn't press the sides of tyres against the rim in the same way. Huck Norris is not meant for running super low pressures. I used to run 2.35bar at the back tyre, now I can run 1.95bar at the back tyre in my enduro race bike with Huck Norris. That is the lowest pressure I'd like to run, since below that tyre folds too much when hitting berms. For the reference on the pressures, I'm 90kg and ride quite hard. I did the Åre Enduro race this year with that pressure at the back tyre, (and I would have run the same pressure even if we had done Hjulingen on SS1.)
Burping is also of course a lot related to the tyre/rim combo used. Use WTB rims and Maxxis tyres and burping is not an issue at all.
2. Benefits of Huck Norris agains Procore
- Huck Norris does not weaken the rim. Actually I don't like Procore at all, if you use something else than Huck Norris, use Deaneasy, it's much better. Main problem with Procore is that you have the high pressure directly pressing against the rim. It weakens the rim a lot. DT Swiss engineers we spoke to were cursing the Procore. You can get some idea of this by measuring the spoke tension before and after installing Procore.
- Weight, Procore is 200g, Huck Norris is 70-75g. That is 140g difference in the most weight critical place on bike.
- So much easier to install.
