Why should I choose a WS2, a Ceramitech, or an ABEC-7 option? What are the differences and benefits of each type?

When it comes to which bearing type is best for you, be it our WS2 coated Ceramitechs, Uncoated Ceramitechs, or our ABEC-7 steel option, it all depends on your goals. If you want to get rid of a creak, and you need a dependable BB that spins very nicely, but you don’t want to break the bank, get the ABEC-7’s. If you want the bulletproof BB plus you want higher performance, you get the Ceramitechs. To get all the features and the highest performance and precision possible to save every single watt possible, you get WS2 coated Ceramitechs. Therefore, we have options.

More technical:

Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB 52. Lifetime Warranty.

WS2 Coated Ceramitech Bearings: We took our amazing Ceramitech bearings and added an extremely durable, tungsten disulfide (WS2) coating that has a 0.03 coefficient of friction---which means it’s slicker than Teflon, graphite, and even molybdenum disulfide. WS2 has an affinity for oils and greases, which means it maintains a hydrodynamic layer of lubricant where it’s needed most. The result is astonishing spin performance and increased endurance. These bearings feature mid-contact seals for extreme performance and durability. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime Warranty.

ABEC-7 Steel Bearings: Crafted from SAE 52100 chrome steel, our BBInfinite ABEC-7 (ISO 492, Class 4) bearings are so buttery that you’d have to buy our Ceramitechs to find anything better. These bearings feature mid-contact seals for extreme performance and durability. Each bearing comes lubricated with Kluber or Koyo. 1-Year Bearing Exchange Warranty.

Why would I want a 1-piece BB vs a 2-piece BB?

The easy answer is to always get the 1-piece (1pc) simply because the entire system is unitized, which means perfect bearing alignment for that perfect spin, and it’s a solid unit, so no creaking possible.

We have BB’s that can only be 2-piece (2pc), such as BSA threaded. But most models, like our BB86-series modules, are offered in 1pc and 2pc options because there are some frames with an obstacle or feature in the frame that cannot be removed, thus blocking a 1-Piece module's ability to cross from one side of the frame's bb shell to the other.

How much do the modules weigh?

Each module model has its weight published under the product description. Go to the BBInfinite bottom bracket page for the type of bottom bracket you desire and you'll find a series of tabs in the product description area. The "info" tab is open already. The last tab "specifications" is where you'll find the product weight along with it's external dimensions.

Do all BBInfinite Modules have bushings in the middle?

No. Only 1-piece modules designed for either DUB or 30mm spindles utilize a bushing due to variances in both DUB and 30mm crank set designs and "set up" from one manufacturer to another. These inconsistencies are mostly in the area of preload adjustment methods that put too much side load on the bearings. These over-preloading situations require the use of a bushing between the inner races of each bearing to ensure proper performance. Shimano DirectFit and Campagnolo DirectFit models do not need a bushing. GXP modules have a short bushing that reduces the bearing diameter on one side, but it is not a full length version found on either BBInfinite DUB or 30mm crank spindle models.

Can I use adapters/spacers with a BBInfinite Module?

We'd rather you minimize the adapter/spacer stack. Technically, it is necessary with some setups, but large adapter/spacer stacks depart from the basic principles of BBInfinite engineering methodology. Large adapter/spacer stacks cause creaks and bearing alignment problems, and will be mostly unnecessary when you can select the proper BBInfinite Module for your frame and crank set for a creak-free, high performance riding experience.

How long do the bearings last?

It varies. Road applications typically last 8,000-12,000 miles for steel bearings and 8,000-12,000 miles for Ceramitech bearings. MTB applications are entirely dependent upon conditions, especially water exposure. Example: A Category 1 MTB racer can usually go an entire season, racing a full schedule, on a single set of bearings of either type. Ceramitechs are better in wet conditions due to a high degree of corrosion resistance.

Will a BBInfinite Module work with my power crank/power meter?

Absolutely. We designed them specifically to be compatible with even the somewhat troublesome-to-fit older model SRM cranks. BBInfinite Modules are compatible with all power cranks/power meters.

Are BBInfinite Modules compatible with my Rotor Qrings / Osymetric rings?

Absolutely. BBInfinite Modules are compatible with all chain rings; be they round, not-so-round, or almost square.

How do I fit my pulleys on a SRAM Eagle rear Derailleur?

Do Ceramitech rear derailleur pulleys require maintenance?

Absolutely. Pulleys are exposed to drivetrain grit and grime every ride, and the pulleys should be maintained accordingly. It's fast and easy and requires no special tools. Watch the BBInfinite Ceramitech Pulley Maintenance Video to see how it's done.

Do I need special tools to install a BBInfinite Module?

We supply the special press interface tools (module driver and a standoff bushing) required with any BBInfinite Module purchase. We designed our press interface tools to work with Park Tools HHP-2 or HHP-1 headset presses and our own bike bottom bracket tools.

Do I need to use Loctite/retaining compound? If so, which type do you recommend?

Yes, we spec a retaining compound. We furnish the required retaining compounds specific to your installation. We send VibraTite 530 with every module, but Loctite 609 or 641 may be substituted.

I’ve recently purchased a BB30A bottom bracket from you to fit a CAAD12. How does the unit interact with the internal cable routing for the front and rear derailleur?

The module has the proper relief cutout in the product. Loosen the cable tension to get the snorkel to drop. To loosen to cable tension shift both derailleurs into the big chainrings, then without peddling shift down on the derailleurs. As long as you don’t pedal the Derailleurs will be held back by the chain and the cables will slack. Align the module cutout with the frame and install. The snorkel will have room to fit back in the frame and module. Done.

The crank spindle will not push into the bearings on my BBInfinite 30mm spindle module. What do I do?

First, check the spindle and use 800-1000 grit sandpaper to lightly polish any spots that are sticking up, if any. Sometimes, even brand new cranks have spindles that are a touch oversized. FSA and Cannondale Si cranks are well known for this. Put the crank spindle in the freezer for an hour. The spindle will shrink enough to allow it to slip into the bearings.

How do I remove a standard pressfit bb from my bike?

It’s easy, and does not require a special tool:

Do you have a PressFit Module installation video?

Do you have a BB90 installation video?

Do you have a T47 internal installation video?

Do you have a T47 external installation video?

Do you have a BSA installation video?

What maintenance does a BBInfinite Module require?

Regular maintenance of bearings in bottom brackets, wheels, and headsets is necessary due to exposure to environmental contamination during use. We recommend cleaning and re-greasing bearings every 3,000 miles to keep them running in top form. If you ride in extreme conditions, such as a soupy cyclocross race or a brutal, rainy, 24hr MTB event, we recommend servicing immediately post race. This applies to all bearings, not just those from us.

We recommend Kluber IsoFlex Topas NB52 for all bearings sold by us. You can get some right here.

Are the bearings serviceable or do I need a new module when they wear out?

Because BBInfinite Modules are not disposable and last a lifetime, the bearings are easily serviced to extend their lifespan. Here is the service video.

Replacing a bearing is fast and easy with common hand tools and an appropriate bearing press. Watch the BBInfinite Module Bearing Replacement video all the way through before starting your own installation.

My bottom bracket is creaking and I've tried everything to fix it. How does a BBInfinite Bottom Bracket module fix a creaking problem?

We fit creaking bottom brackets with proper engineering and precision machining. Watch this brief BBInfinite primer "PressFit Perfection" to get the lowdown on how we do it while all others fail.

I heard that PressFit bikes just creak. Is that true?

No, that is completely false information. PressFit bb's offer the potential for the highest level performance possible, thanks to BBInfinite. There is no reason for your PressFit bike to creak, crunch, crack, or make any noises at all. Unless the frame is cracked the bike will be quiet.

Can a creaking and popping bottom bracket damage my frame?

Yes, it can. A creaking bottom bracket means there's movement between the bb and the frame. The more a bicycle bottom bracket creaks the more it is moving. This movement over time can wallow out the frame bb shell openings, enlarging them and elongating them, making them more susceptible to creaking and making it impossible to fit new bb's. Don't freak out, it takes a long time. We've seen only a handful of bikes go in the junk heap due to bb shell ovalization. Install a BBInfinite module to save your frame, and your sanity.

Why does my BB90/BB95 Bottom Bracket creak?

This happens a lot. Often the BB was never creaking or was just one of several noises. It’s common, and not the hardest to fix, but the important thing is to avoid fixating on the bottom bracket as the culprit until you know it is for sure. Have a look at this blog Kill that creak.

After installing my BBInfinite module into my BB86/BB92 frame, my DUB or PressFit crank doesn't spin well. What should I do?

1) I'd like for you to take the crank out and ensure that the aluminum bearing shields can spin freely on the bearing. I want to make sure they are not rubbing on the inner diameter of the bore on the DS. Sometimes as the bb passes through the frame the nose of the module can get deformed a little and intrude on the bore, thus rubbing the outer diameter of the shield.

2) Next, if that's good, I'd like for you to use the black plastic driver that fits in the 4030 bearing to "press" the bearings in. If you have our press, use the metal dies marked 4030. If you have the provided, black plastic module driver that was used to install the BB, use it on one side to press the bearing in, while on the other side use the installation cup seeing that you don't have another die to press with. What we're doing is making sure a bearing didn't get dislodged during the install or crank install. If a bearing gets pushed off its locating backstop that'll cause the binding drag you are experiencing. So go to both sides and "press" the bearings in to ensure they are seated.

These are the common causes of spin degradation on a new install.
