Wheel options for standard wheel replacement

edd1e · May 12, 2020

Can someone please help answer me these questions. All in relation to replacing the standard (non forged / non carbon wheels) on a gen 4.

1 - Do forged HP wheels from a Gen 3 fit? Does anything else need to be changed, spacers / discs / sensor rings etc?
2 - I assume a set of OZs will slot straight in with the standard discs??

1. No

2. Yes. But rear carrier will be different and hence you need different rear sprockets.

Nothing wheel related transfers from Gen3 -> 4 afaik.

Yeah thats correct, applies to OZ as well.

OZ for Gen3 wont fit to Gen4.

You would need OZ for Gen4.

OZ for Gen4 comes in few flavors too

OZ Piega/Cattiva from OZ directly. Rear carrier has same dimensions as Gen3, hence you can re-use HP Forged/OZ rear sprockets.

OZ Cattiva designed by Alpha, sold by Alpha. Rear carrier has a different diameter and would require special Alpha sprockets.

Gen 4 Wheels

Ideally, you need to buy Gen 4 specific wheels. Virtually no parts are transferable from the Gen 3.
