Why does my bike make a creaking noise when I pedal?
The most common cause of creaking is the crank being loose on the spindle. Remove the crank bolts, lubricate the threads and under the bolt head, and reinstall. Tighten the bolts to the manufacturer recommended torque. Use a torque wrench if possible.
How long should BB30 bearings last?
It varies w/ every bike/rider. There is no way that anyone can provide you w/ an accurate estimate of how long bearings will last for you. If you bought the bike 5 years ago and they’re just starting to make noise now I’d recommend replacing the next set after 5 years.
How long should a BB30 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.
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.
Why is my BB30 bottom bracket creaking?
The leading cause of BB30 bottom bracket creaking is bearing migration within the frame bb shell during use. The bearings shift around a minute amount, resulting in the dreaded creaking sounds. Typically somebody greases the bearings to fix it. This only masks the problem, or more often, exacerbates the problem.
What kind of bike is a BB30?
BB30 was rolled out by Cannondale years ago in alloy bikes. It’s a superb economy of components from a design standpoint: bearings press in frame, crank slides into bearings, BOOM…done. And then it creaks. You fix it. A few weeks later your bottom bracket is creaking again.
What’s the difference between BB30 and pressfit30 bottom brackets?
BB30 bottom brackets call for bearings to be pressed directly into 42mm ID interfaces in the frame bottom bracket shell whereas PressFit30 bikes have 46mm ID frame bottom bracket shells and use a housing, often plastic, with a bearing pressed in it to do the job. We’re only talking BB30 in this article.
