The stainless freehub bodies and INA bearings should last forever and True Precision says they will replace these parts for no charge with a service if required.

When I saw that they would be at Interbike this year they were a must visit. True Precision were silent exotica at that point. The big money was always on Made in the USA hubs which meant Profile Racing or Chris King BMX hubs for the bulk of our discerning customers.
