Make Your SystemSix Faster and Dead Silent with BBInfinite Press Fit

Описание: It’s finally here, the Cannondale SystemSix, and we’re blown away by its aggressive looks, it’s astounding
fit and finish, and its superb, right-out-of-the-box performance. But this bargain basement, two-piece pressfit bottom bracket is like putting clown shoes on a thoroughbred.
Let’s give this mighty SystemSix the one-piece pressfit weapon it needs to swiftly and silently dominate group rides and race days alike.
We removed the old bb and, following the instructions to the letter, cleaned and prepped the frame.
Check for obstructions
Hand start the PF30A bb in the frame.
Insert the press.
And press until the bb becomes loose in the frame.
Apply the VibraTite,
We applied the Vibratite to bond the PressFit30A module into the frame. This ties both sides together, and it really stiffens the frame shell, in a structure that is already very stiff. Yes, the creaking is normal, and it’s a good sign, that the Loctite has lit-off.
Grease the crank
Install hardware
We froze this Si crank for half an hour to ease assembly
Install the correct crank spacers
Grease the crank bolt and tighten the arm.
And torque everything to spec.
This is what full potential looks like. Visit bbinfinite.com now to find out how YOU can become infinitely faster.
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 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.
