Don't pull the module out just to service or replace bearings. If all you need to do is service the bearings in your BBInfinite module, or in your Trek BB90 bottom bracket, check this out: BB8Infinite Bearing Maintenance
Product Service Section: 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 replaced while the module is installed in the bike. It's fast and easy with common hand tools and an appropriate bearing press. Watch the BBInfinite Module Bearing Service video all the way through before starting your own installation. Do ceramic bearings in a BBInfinite Bottom Bracket Module require regular maintenance?? 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.

Email us at email@example.com and let know the bicycle frame type (e.g. road), frame manufacturer, frame model and model year, and crank type (manufacturer and model), and with this information we'll reply with a link directly to the product you need. Attach a few pictures showing the crank and bottom bracket area clearly, and one of the entire bicycle to aid us in our quest to get you on the right track. Creaking Bottom Bracket Section 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 bottom brackets 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 bottom brackets shell openings, enlarging them and elongating them, making them more susceptible to creaking and making it impossible to fit new bottom brackets. Don't freak out, it takes a long time. We've seen only a handful of bikes go in the junk heap due to bottom bracket shell ovalization. Install a BBInfinite module to save your frame, and your sanity.
General Bottom Bracket Information Section: 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 modules designed for a 30mm spindle require a bushing due to variances in 30mm crank set design 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 BBInfinite 30mm crank spindle models.. bracket tools.
Use a drift and a hammer to walk the bearing out in an alternating pattern on modules featuring a bushing between the bearings simply push the bushing out of the way to gain access to the race offset blows to correct alignment as the bearing emerges use White Lightning clean streak or denatured alcohol to thoroughly degrease the module bore continue cleaning until the paper towel comes back spotless the same goes for the bearings oil and grease are the enemy of retaining compounds a trace amount will inhibit adhesion and prevent curing apply a small amount of Vibratite to the outside of the bearing using a q-tip or a clean oil-free gloved finger distribute the Vibratite across the circumference of the bearings start the bearing squarely in the bore if your module features a bushing between the bearings reinsert it before setting bearings in place install the press according to tool manufacturer's instructions ensure that the press is properly setup and the bearing is straight in the bore before commencing if the bearing becomes cocked. Stop pressing, remove and reinsert bearing before recommencing when the bearing is seated the operation is complete clean off excess fiber tight and install the crank set according to manufacturer's instructions.
