• 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).

    Yeah, but these are GOLD!!

  • 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.
