Ceramic Bottom Brackets

Barcode: 0735201953212



This bottom bracket fits the M30 spindle of Praxis and Infocrank on a Cervelo frame with BBRight bottom bracket.

The set consists of our BBRight to 386EVO bottom bracket with road or cross bearings and a non-drive side reducer that will fit the 28mm stepdown of the 30mm Praxis spindle. This setup will space the bearings at maximum width, right next to the crank arms, to maximize your drive train stiffness and reduce bearing wear.

If your Cervelo is a model year 2023 or later, your frame might have a threaded version of BBRight. You will find these bottom brackets under T47Asymmetric in the dropdown.

Choose road bearings for road bikes, cross bearings if you frequently ride on wet roads or gravel.

"When I first built my new super-bike with the sole intent on going as fast as possible, I decided to save a few bucks by not spec-ing a ceramic BB despite running one successfully on its predecessor for several years. That was a mistake. I could clearly feel how "sticky" the stock bb was whenever I removed the chain for cleaning and waxing. Having just recently installed a new Kogel BB, there are now truly, "no excuses.""

"These bottom brackets don’t quit! I’ve run this PF30 with CX seals on two generations of cyclocross race bikes - two matching bikes per year across four years. Demanding use, lots of washing, AND riding over winter in Eastern Canada, which involves snow, ice, and salt. Every BB held up without issue; set and forget. Amazing!"

Frequently asked questions

What is the warranty on Kogel Bottom Brackets?

Guaranteed Performance means working hard to make your experience with Kogel Bearings the best possible, every step of the way.

Kogel Bearings takes pride in delivering a best-in-industry warranty. Our 2-year warranty means you can feel confident and secure about your next two seasons of riding.

If a product fails in the first year, we will replace it. The second year requires an annual bearing service. A manual for that service can be found here.

How can I tell if my Bottom Bracket is worn out?

Bottom brackets fail for many reasons. The most common being contamination and neglect. Remove the crank set, spin the bearings to check if the bearings feel rough. If they do, a bearing service should bring them back to life. If the service does not help and the bearings still feel gritty, it is time to replace them.

Proper care is key to longevity. We recommend annual service to stay within the Guaranteed Performance Warranty, or sooner if your bearings feel rough. The current recorded mileage record is set at 28.000 miles on a single bottom bracket. What. Does your BB odometer tell you?

How hard is it to to replace a Bottom Bracket?

While the procedure is not too complicated, the job is almost impossible to do without very specific and potentially costly tools. A wood block and hammer are not a bottom bracket press, neither is a threaded rod from the hardware store and a stack of washers. (here is a link to the procedure)

If you regularly replace bottom brackets on multiple bikes, it might be worth investing in the tools. If you only perform this procedure occasionally, it’s probably better to carry $50 and a six pack to your local bike shop and let the professionals take care of it.

How do I fix a creaky Bottom Bracket?

While we do not require to use our Aqua Proof Installation Paste, we call it Shut Up Grease for a reason. Pick up a jar or a single use syringe here. A simple remove and reinstall with all contact areas greased (most crucial are the BB shell, BB cup and crank spindle)

If that did not fix the problem, here are links to two blog posts on 1) fixing bottom bracket creaks and 2) finding and fixing creaks that sound like a bottom bracket, but actually come from somewhere else.

Are there any benefits to using cross seals on my road bike?

The cross seals are built for best protection. The difference in friction between the road and cross seals are around 0.5W on a bottom bracket. On the upside, bearings with cross seals are close to waterproof. If your road rides include gravel roads or if you regularly ride on wet roads, the cross seals will buy you some peace of mind.

How much do bike shops charge to install a bottom bracket?

The hourly rate varies from one shop to the next, mostly based on their expenses for real estate and the cost of finding good mechanics in the area. For this reason it is hard to put an exact dollar amount on the procedure. It would be reasonable to expect an installation to take around 30 minutes, so half of your local shop’s hourly rate is a good benchmark.

How can I tell if my bottom bracket needs servicing?

Just like your chain and cables, bearings need to be regularly serviced and work MUCH better when properly lubricated.

Inspect your bearings at least every few months (always after extreme wet muddy rides) and service your bearings at least once a year. 

Easiest way to inspect a bearing is by removing the chain from the crank and spinning it using your fingers. The bearing will fall somewhere between these three conditions:

  1. Clean - feels like it’s spinning effortlessly in fresh grease
  2. Dirty - feels like it’s spinning with some grit in the grease
  3. Dry - feels like it’s spinning effortlessly, but it’s making more noise than usual

With this simple test, you can get a good sense of your bearings being contaminated, damaged or good for another ride.

If they feel gritty, you'll want to service them. Here is a link to the best practice in pulley service. And at a minimum, they’ll need to be serviced a year from their install date or last service.
