I'd like to know what is better in terms of maintenance and reliability in the long term.
I currently have a flip flop hub with a freewheel which I had to replace recently. For what I saw there were not many options in the market and they where quite expensive (white industries around 100€, halo clickster around 50€ and some other cheaper options which I don't trust anymore).
Depending on which one you buy, I've read they last around 2000-6000km (the cheap one I had was under 2000km...).
I'll replace my wheels in the future and probably I will have a custom build so I can choose the hubs.
The track hub for example, in shimano dura ace is around half the price of the freehub. The hb900 costs around 240€ and a campagnolo super record pista or dura ace 7710 around 120€.
Is it worth it to buy the freehub or are there other things to take into account? Will the freehub fit in a bike that had a freewheel hub?
