Help with Zipp 303 S freehub please

[TomP]

I have a set of Zipp 303 s wheels with the SRAM XDR freehub. I would like to improve the engagement speed, but Zipp says there is only their 3 pawl freehub. Do any of you know if there is a freehub that would work that has more pawls for a quicker engagement? Thanks.

More pawls do not equate to faster engagement. More "points of engagement" or notches in the ratchet ring, which, given a fixed diameter mean the notches are closer together = faster engagement.

FYI.

Thanks. I didn't know that.

Some freehub bodies use more offset pawls to increase engagement. Only half the pawls engagement any one time, so they effectively double the points of engagement for the same number of notches in the ratchet ring. Ibis, for example, offers such a freehub. https://store.ibiscycles.com/product...t-freehub-body

I don't know if there is an upgrade like this for zipp hubs.

Careful with those Zipp pawls they fly away and disappear like magic.

I'd have to question why you want to do this. If you're using these for road, it's very likely to be a downgrade rather than the upgrade you seek.

I have a left foot drop, partially paralyzed left foot, and quicker engagement works better for me.

That would be a good reason then. Unfortunately I don't have a suggestion for the part you're looking for.
