This hub sounds great, engagement is also great.
Had a bit of problem with not knowing exactly what to order, 20twenty been really helpful on this matter
Was going to but the pro4 when I saw the initial reviews for the 5. The design is much smoother looking. Weight is great for a mtb hub, engagement is quick and responsive. Noise isn't bad, louder than my old Kings but much quieter than I9, I'd rate the noise about the same as White Industry. Built with a 3mm OC rim resulted in only a 1mm difference in spoke length and very close spoke lengths, the NDS at 115kgf vs 125 on the drive side for a solid build. I expect years of smooth, trouble free use.
