Are Press Fit Bottom Brackets Good?

Are press fit bottom brackets good? There are benefits to press-fit bottom bracket cups. They are lighter than traditional threaded cups because there's no metal sleeve required in the bottom bracket shell. They can also allow for wider shells and correspondingly bigger frame tubes, for improved stiffness without an adverse effect on pedal-stance width.

How do you press a bottom bracket?

How long does a press fit bottom bracket last?

Simple rule is (unless you're starting a long trip) "if it ain't broke don't fix it". Do normal maintenance, keep things properly lubed and your BB should last for another 4,000 miles or more.

Should I grease press fit bottom bracket?

Do press fit bottom brackets creak?

The reality is pressfit has nothing to do with creaking. There are many areas of a bike where bearings have a pressfit and there are no problems. Once a misalignment in a bottom bracket is evident, the hardened bearing surfaces wear the bottom bracket down and the shell becomes a slack fit and thereby causing creak.

How does a press fit work?

In engineering terms, a press fit— also known as an interference fit— is the fastening of two parts that is achieved by normal force, friction and cold welding. This happens when a shaft is inserted tightly into a slightly smaller hole in another part, with the interference holding both parts in place.


How often should you grease bottom bracket?

Best practice 1-2 years depending on use and grease quality. If you're cycling in a lot of rain or off-road 3-9 months is a better bet. If it's a cheap bb and you don't care about failure then let it eat so long as it's adjusted and running smooth.

How important is pressing during assembling?

Press fits are also used to prevent bearings from spinning. It is a good fastening method for components that undergo temperature fluctuations, such as automotive assemblies. Regardless of the temperature, the interference fit or force between the two parts is always there.


Should I grease crank spindle?

So for our René Herse cranks, we recommend that you lightly grease the crank spindle. Crank bolts can loosen over time, but that does not mean that you should re-tighten them. Instead, remove your cranks every couple of years and inspect them for cracks. (You should do this with all cranks, no matter the brand.)
