The bearings in the back wheel of my Stache 5 are totally goosed, have been for ages. Now winter’s here and I’m going to be riding it more I am finally getting round to replacing them.

I can’t for the life of me find the info for the hub on the internet. Has anyone replaced the bearings in this hub (it’s the same as the one on the Stache 7), if so what size did you use?

What year, any pics?

It’s a 2016. This is the bike, the wheels are stock-

The hub is a Formula one, all the writing on it is “Boost 148” – nothing else.

Not seeing that pic. Is it a Formula DHT 148 hub?

That’s the one. Looks like 6903 from that thread (I’ve seen the thread before and that last post wasn’t there when I last checked!). Anyone know if it’s the same for the freehub?
