Trek BB90 Is Amazing When You Do It The BBInfinite Way
From the mighty Madone to the cross crushing Boone BB90 offers superb spin performance low weight and unparalleled stiffness when you do it the BBInfinite way let me show you how right now using an appropriate drift or a BBInfinite mts one in drift configuration walk the bearing out a twelve six nine three type pattern clean the bottom bracket shell with denatured alcohol or white lightning clean streak for BB ninety standard kids apply the Vibra-tite 530 the outer races if the Vibra-tite is running off you have applied too much for BB90 GXP kits install the non-drive side bearing and then the GXP bushing install the drive side bearing now this is totally normal if you hear this creaking sound right here totally normal now if you have a BB90 kit for Shimano you can drive both bearings in simultaneously and now if this was a repair kit you would leave this in for 24 hours this is a brand new frame in perfect condition so we're going to move on finish with kit specific hardware and install the crank only use what is provided with your BB90 kit do not use old hardware. I'll have to give the crank a little bit of a spin just to make sure nothing's binding and torque it to spec.
We installed one of our BB90 Ceramitech kits in this gorgous new Trek Boone. This is going to serve as our new Trek BB90 installation vid as it addresses several questions we got regarding our "classic" BB90 installation vid...blah blah blah...it was an excuse to feature a Boone. What a bike! Here's a link to our maintenance video; https://youtu.be/9wtP2rRjR2E And our BB90 pages: https://www.bbinfinite.com/products/trek-bb90-shimano https://www.bbinfinite.com/products/trek-bb90-gxp?variant=45881541710 Product Selection Section Which type of bottom bracket module do I need?? Email us at info@bbinfinite.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 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. 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.. Can I use adaptors with a BBInfinite Module? We'd rather you didn't. Technically, it is possible, but such action departs from the basic principles of BBInfinite engineering methodology. Adaptors cause creaks and bearing alignment problems, and are 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.
