These babies have zero ceramic bearings, alloy axle and Ti fixing bolts. Some people have to have the best...
Goldtec track hubs have long had an enviable reputation for being indestructible. So quite why the manufacturers see the need to try to improve on an already awesome product, I'm really not sure.
But improve they have, by bumping up the spec to include ceramic bearings. Bearings are the vital component of a hub - if there is one thing that is worth splashing out on, it's good bearings.
Lockrings aren't supplied - we recommend the Andel lockring with these hubs. We get these built to order by Goldtec, and delivery time is usually around a week.
