HASSNS PRO7 MTB Hub Bearing Technology and Specifications
The sealed bearing technology protects internal components from mud, water, and debris encountered on aggressive trail rides, extending service intervals significantly beyond unsealed alternatives. Dual hole options—32H and 24H—accommodate virtually every modern wheelbuilding strategy, whether you favor wider or narrower spoke patterns for your specific terrain. Multi-speed compatibility spanning 7-speed through 12-speed cassettes means the HASSNS PRO7 integrates seamlessly with current and legacy drivetrain standards. Each bearing races meets ISO tolerance specifications, delivering smooth rotation that persists through seasonal weather changes and high-mileage use. Bushing construction reduces weight while maintaining lateral stiffness, a balance critical when climbing steep grades or absorbing impact from rocky descents.

They are very lightweight and arrived very quickly. I highly recommend them; it was a gift I gave to my husband and he liked it a lot.

It’s loud the way the 244 likes it, everything arrived safely inside the box and with the axle, the quality is amazing and the price is very cost-effective, in other words, everything is good to buy without fear. Mine arrived in 10 days, super fast too. I don’t have the photo here because I already had it installed on the bike, but you can trust me, it’s great.
