We had a ton of different versions of these before we settled on the final one, some required individual carbon moulds for every size which would have made the price even higher (yes I know it’s high already but machining a dinner plate out of a block of very very high quality non stressed Ti is difficult, and also pretty much wrecks a cutting tool on every chainring so they’re replaced constantly).
We’ll definitely have a couple in the Olympics but have another first batch which may make it in too, will be tight though.
Xav's new chainring will be on the Christmas wish list for people using 144mm PCD cranks, claims 0.1% speed gain (25cm per 250m)
I paid considerably less for my Vuma Chronos, for which Zipp claimed a 0.25% speed gain (9s per 40km).
