Types of Bottom Brackets & Bottom Bracket ShellThe crank bearings are part of the bottom bracket assembly that slots into the round bottom bracket shell on the bicycle frame. This part will contain the spindle that is the axle of the crankset; this part inside the shell allows the links bearings to move smoothly. The crank bearings are connected via spindles with one being attached on the surface and one directly into the frame. There are a number of different bottom bracket configurations. Older bicycles tend to have something known as a cup and cone bracket. Whereas many new bicycles, use cartridge bottom brackets. Types of Bottom Brackets
- Loose Bearings – Three piece assembly with separate spindle and cranks
- Cartridge – Sealed units holding the bearings and the spindle
- One Piece – Spindle and crank arms are a single piece with bearings pressed into the bottom bracket shell
- Pressed Bearings – Bottom bracket with bearing pressed directly into the bicycle frame
Threaded Bottom BracketsThreaded bottom brackets come in a number of different versions. Cheaper and older designs use threading bearings that sit inside the frame with a captive (fixed) axle that the crank arms are tightened onto. There are a multitude of standards for the captive axle. The most common and cheapest is a square interface (square taper), but Shimano offer a multi splined (Octalink) interface and there is also a standard called ISIS, though these latter two are rarer, having been superseded by other designs. Most modern threaded bottom bracket designs now use a three-piece design that has a pair of larger diameter bearings that sit outboard of the bottom bracket shell, which is an axle that is permanently fixed to one of the crank arms threads through.
This design has a large advantage in that the thread bearings sit outside the bottom bracket shell and can be of a much larger diameter, making them much more hard wearing. The axle can also be made thinner and lighter. These designs include Shimano Hollowtech II and SRAM GXP, although these two systems aren’t compatible.
Press-Fit Bottom BracketsPress-fit bottom brackets that don’t require a threaded bottom bracket shell on the bike frame are becoming more popular. They allow designers to make composite frames system that don’t require tough inserts for the bearings to sit in. There are a number of standards here too. Shimano’s Press-Fit 92 uses the same spacing as their external, threaded Hollowtech II system and is cross-compatible with those cranks using the right 24mm spindle. The bearings are highly important, as their quality dictates how much energy is lost as friction and how long they’ll last. If they are within your budget fully sealed cartridge bearings are preferable. They are non-adjustable, fit and forget units that don’t need any maintenance but have to be thrown away when they are worn out. More expensive units use bearings that have much higher tolerances, resulting in less friction and longer life. Mountain bike bottom brackets often have a larger amount of sealing for the increased demands of off-road use, which increases friction as a side effect. More lightly sealed, lower friction ‘Road’ versions are also common.

Which Bottom Bracket is Right for You?To some extent, the type of bottom bracket you choose will be determined by your frame type and compatibility, as some frames – particularly carbon models above a certain price point – are made to use one type of bottom bracket, and one type only. With some bottom bracket types (anyone remember cottered cranks?) having died out completely, there are three main designs remaining – the cartridge-type bottom bracket (itself a declining standard); the external or outboard bottom bracket and the press-fit bottom bracket (with this latter type becoming more and more commonplace). Inexpensive, easy-to-fit and well-sealed cartridge bottom brackets are still found on lots of MTB and road frames at the more budget or utilitarian end of the market, with external bottom brackets at one point having largely replaced them on higher-end models. However the increased use of carbon fibre as a frame material has also led to a growth in press-fit bottom brackets being specced as standard on mid- to high-end carbon bikes, as well as some aluminium models. It’s one area we are seeing a lot of divergence in at the moment, with different manufacturers using different standards, for different claimed benefits.
Whichever type you choose – or are obliged to stick with – make sure you choose the correct width to fit your bottom bracket shell. These are generally 68 or 73mm wide on MTBs, or 68/70mm on road bikes although again this is not such a consideration with press-fit bottom brackets.
Hybrid Ceramic, Stainless Steel and Steel Bottom Bracket BearingsHybrid ceramic, stainless steel and steel bottom bracket bearings all have their advantages. However, you may find that hybrid ceramic bottom bracket bearings are generally more expensive than the other options due to the expected increased lifetime of the system & the performance gains, it all depends on what type of bike you have and what type of riding you do. If you’re not sure, call & speak to our company today & we’d be happy to help.

How to Remove Bottom Bracket Bearings? Inspect the threading and threaded bottom bracket bearing cups for tool fittings. There are many different designs and tool options. When you have the correct tool which is needed, insert the tool fully and remove the non-drive (left-side) cup by turning counterclockwise, holding the tool firmly to the cup. Removing an internal sleeve, it’s important to take note of any spacers under the cup for reassembly.
How to Replace/Change Bottom Bracket Bearings? With your new/replacement bottom bracket, grease both parts of the tubes and threads using the paint brush. Apply enough grease so that the threads are evenly coated. Insert the bottom bracket from the drive side of the bike with the larger side facing your hand and gently screw in the second set of threads on the other side with your fingers. Use the bottom bracket tool to screw in the larger side (drive side) of the bottom bracket, make sure to screw it in counter clockwise. Screw the threaded bottom bracket in all the way, but make sure not to tighten it down. Repeat for the smaller side, except screw the bottom bracket in clockwise, tighten both sides down with the bottom bracket tool. Put the cranks back on their corresponding sides, making sure the chain goes back around the chain ring and put the bolts back through and tighten them into place with the allen wrench used earlier. Finally rotate the pedals with your hands to check that the bottom bracket is rotating smoothly and not catching.
How do I know if my bottom bracket bearings are worn out? You can usually tell if your bottom bracket bearings are worn out if you can feel an obvious rumbling, creaking, grinding or stiffness. This will tell you that the bearing is worn out and should be replaced. If your bottom bracket is severely corroded or worn out, you will be able to hear a grinding noise. For more information on this, check out out blog on What is the Bottom Bracket on a Bike now!
How Do I Know the Size of my Bottom Bracket? The best way to find out the size of your bottom bracket bearing is to check for a code, if you can’t see a code you will need to measure the bearing. If you measure the inner, outer & width of the bearing you will be able to identify it from that & you can input those dimensions in our handy search bar at the top of the site.
How long can a bottom bracket bearing last for? We wouldn’t want to make a generalisation as to how long a bottom bracket can last for, this is because there are too many factors to consider including weather & the number of miles the bike has done etc. You can always speak to the expert team at Aire Velo if you need any further assistance.
How to remove sealed bearings from the bottom bracket? More and more bikes now come with bottom bracket bearings that will push into the frame. Should your bottom bracket bearings have worn down, are damaged or corroded, you’ll need to remove them, these bottom bearings won’t be held in place by threads in the frame, they will be pushed into place and held by friction. Sometimes, this won’t work well and the bottom bracket bearings may creak, to fix this you can replace them and use a thread locked to hold them in place.
Can bottom bracket bearings rattle? There are a number of reasons why your bottom bracket bearings may rattle, this usually indicates a problem with the bottom bracket itself. There are a range of things that you can do to check this, this includes pulling your cranks laterally and seeing if they move, you can also remove the chain from the chainings and give your cranks a spin, when you do this, listen for any unusual grinding noises or little clicks, you can also test this by holding the tube or seat tube down while spinning the crank then see if you can feel any grinding or vibration through the frame. Any of these points will indicate that you need to service or replace your bottom bracket.
What bottom bracket do I have? In order to find out the size of the bottom brackets that you need, make sure that you measure inside of the bottom bracket shell in your frame, it will be either 73mm, 70mm or 68mm. Some older frames may come with threaded bottom brackets instead.
