SRAM Zipp Bearing KitFor road riders, Zipp Wheels represent some of the highest performance options available on the market today. But for those cyclists looking to eke out every performance gain possible, the company is now offering an upgrade kit.

By teaming up with Ceramic Speed, Zipp has developed a new Upgrade Bearing Kit for use in all of their hubs and freehub driver bodies. Each of the kits includes low resistance hybrid ceramic (ceramic balls and steel cages) bearings, and offer a measurable wattage savings between 1.5 and 9 watts per bearing set, depending on the condition of your existing bearings.

Pricing and more kit information after the break.

  1. Am I reading this correctly that one kit is required per wheel, so your talking a $500 upgrade per wheelset on a wheelset that already costs $2600? How are these 3-5x better than Endro Ceramic bearings?

  2. Ha! They cost more than the super precision bearing we use at work (for space applications) and 6-8x more than other ceramic bearings. I would love to stick them in one of our test rigs and look at the torque versus a range of other options

  3. Overpriced bearings on overpriced wheels. Zipp rims are decent, but their hubs are junk. For a $3k wheelset they could at least give you decent hubs and not try to pry another ~$500 out of your hands for snake oil bearings. You would likely save more watts with shoe covers.

  4. zipp surely knows how to make money. design sh*t wheels, sell an expensive upgrade to fix a problem all their products have..

    who has a good source for super precision steel brgs that ships to EU / NL? matt?

  5. GRW or Barden come to mind, if i were into that kind of thing (which i’m not), i’d have training wheels and then race wheels, with metal shielded bearings running oil impregnated phenolic cages, you’re likely to get lower torque resistance than any rubber shielded bearing

  6. This is the equivalent of someone racing a F1 race car made by Toyota, and then Toyota sending them a mailer telling them that their car isn’t all that it could be, and that upgrading the paper air filter is the difference between second place and world fame.

    “You have the very best wheels, but…they could be better.”

  7. Good Dr., Toyota has been out of F1 for near a decade…

    I’m with some of the others, I can’t see how these are that expensive. Enduro Zero bearings seem to have a lot more going for them, at least on paper. Ceramic Speed also doesn’t list any spec on their bearings, at least that i can find.

    What grade are the balls? 5? 3? 100? What is the ABEC rating? 9, or 1?

  8. This is part of the reason why I purchased Rolf Prima wheels, instead of Zipp. Rolf’s carbon wheels already include factory-installed ceramic bearings (made by Enduro), and are priced still several hundred dollars below Zipp, despite Rolf being handbuilt in Oregon. Moreover, Rolf’s hubs are made by White Industries in California, while Zipp’s are made I don’t know where exactly in Asia.

  9. Zipp is fully aware that this is not for the regular consumer. There’s an interview with Zipps technical director who said that this would be absurd for the average rider. Their steel bearings are one of the highest grades and better than most ceramic bearings in the market. But they offer these high precision ceramic bearings so the ultra elite riders who want it have that option.

  10. You can buy ceramic hybrid bearings from the HubDoctor, (Orange, California), for about $10 each. I replaced my PF30, front and rear hub – 8 bearings in all for less than half what ZIPP is charging.

    In your hand, they are smoother and with less resistance compared to regular new bearings. After the seals break in and bearings loosen up a bit after a few rides, you will notice how much better they freewheel in the stand. This translates into less energy expended. How much better I couldn’t tell you, but according to ZIPP, a measurable amount.

  11. @Victor: the “ultra elite riders” are sponsored. They’ll never need to spend money on Zipp (or any other) after-market ceramic bearings. Zipp is clearly offering these ceramic bearings for non-professional cyclists.

  12. Lots of brands offer this type of upgrade or just super high end hubs like DT 180s. I agree though that you can get bearings just as nice for super cheap. I get smaller ceramics online for dirt cheap from an RC car shop. They work perfectly in my AC hubs.

    Also, Zipp wheels do not suck. Try the latest gen 404 tubs with some FMB tires and then find me a better feeling road wheel.

  13. If there is measurable wattage savings between 1.5 and 9 watts per bearing set, then there would be measurable heating of respective steal bearing.

  14. haha, what a nonsense, if you have the legs to win, you win, even with old fashion style hubs with single steel balls!

  15. Boris – what about when 5 or so guys have the legs to win or at a photo finish? I personally don’t need them, but some people make tiny gains via equipment after they are in perfect form and fit.

What do you think?
