You don't always have to remove the bike chain just to get it up out of the way for when you're performing a procedure such as removing the bottom bracket and installing a BBInfinite module. Here are some quick tips on how to handle it. Product Selection Section Which type of bottom bracket module do I need??
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.
So your bottom bracket is creaking and you'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 is movement between the bottom bracket and the frame. The more a bottom bracket creaks, the more it is moving. This movement over time can wallow out the frame bottom bracket 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 individual module 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 its 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.
Well before we can do our spin test or our installation or any other work on the bottom bracket of this bike, we need to get the chain out of the way and I'm going to show you some quick strategies on how to handle it no matter what kind of chain you have. Alright the first strategy is if you have a Shimano type chain or any chain that is pinned you don't want to have to remove the pin because then you're going to have to have another one on hand and it's unnecessary to take it apart so we're going to go like this I'm just going to push the rear derailleur down and I'm going to reach forward now the tension is off the chain and I'm going to bring it around the pedal and the crank arm and now I have the chain out here like so and then I'm just going to loop it up and over the derailleur and let it sit just like that and then let the tension off the rear derailleur and once that is done now as you can tell the critic spins really all right strategy 2 has to do with any chain that has a quick link that would be a KMC Oris RAM and several other on the market such as whip ermine I'll show you how to do that right now and you don't need any special tools all you need is a pair of pliers with a slip joint let's see how this works. So even if your chain has a master link like this or a slip link/quick link whatever they want to call it it's a link like this it slides together you still need to loop it like you do if it was a Shimano style or a pin style chain like can't be in whatnot so get to this point so you've got no tension on it and that's when you can come in here with your pliers and from experience I know I can adjust them right about that and you're just going to form kind of a Z just like that what I'm doing is I want to get the pliers on the back end of this plate which is the one that's pinned rather than the one where the slide is and that's where I want to get the lower jaw here and then what I want to do is I want to get the upper jaw on the opposite side just like that and then I can push them and it snaps them apart very easily and now I can remove the chain but not so fast don't just go taking it off because I can tell you from experience that a chain with some miles on it as you can see from my hands this is not some pristine bike we just dragged in off of the bike rack this thing has got miles on it we want to take this chain that's still good it's got about 1500 miles on it still got some life left we have to mark it here's how I choose to market I use a zip tie and I come through the top alright and I zip tie it so that the zip tie is oriented with the block piece the lock facing out okay and looping up and over what is the top of the chain when it's installed this way I know how to orient it that need the chain needs to flow this direction with this set of plates facing out and this will avoid some serious shifting problems that can happen from you putting a chain on backwards subscribe to our YouTube channel to find all of our videos where you will see installation tips and helps and introductions to new products follow us on social media outlets Twitter Instagram Facebook don't forget to like us and best thing of all go to be BBInfinite calm you will see all of our greatest propaganda about all the greatest products in the world check us out
