How long should a 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 I maintain my bottom bracket?
Every three months or so I’ll take the cranks out and if it’s a threaded bb, I’ll remove the bb and do the full service. Around the three month mark is normally enough time, even in the best conditions for dirt to work its way into the small gaps and contact points around the crankset and bottom bracket area.
When should I upgrade my bottom bracket?
Reasons to go for the upgrade Usually if both chainrings and the bottom bracket are worn out, you might as well upgrade to the new setup rather than buy all the parts for your old unit. Besides getting something that matches the rest of the parts, you’ll know you’re hammering on brand-new crankarms, too.
How long does a SRAM bottom bracket last?
Generally ride it for about three months through winter, once a week, 20ish miles each time – that’s only 250 miles a year so while the SRAM BB on it did last over 4 or so years, it had probably only done about 800 miles when it was replaced but it only gets used in filth.
How do I know if my bottom bracket bearings are bad?
If you feel an obvious rumbling or grinding feeling, the bearing are worn out and the unit should be replaced. Very worn bottom brackets will actually make a grinding noise.
Should I grease my bottom bracket?
new grease won’t cure worn out bearings and races. so, to answer the original question, no, you don’t need to lube the bottom bracket.
How often should you replace crankset?
My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer. A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.
Why does my bike creak when I pedal hard?
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.
When I pedal my bike it makes a clicking noise?
A clicking noise is the most common sound your bike can make. It can be due to the rider pedaling fast, and the chain wants to jump up and down the rear cassette to accommodate the demands of the pedal. To identify the sound, you can slow down from pedaling and observe whether you still hear a sound.
What happens when a bottom bracket fails?
Eventually your bearings will disintegrate and your BB will lose its ability to hold the spindle centred withing the BB shell, that will result in the crankset becoming wobbly, your chain will come off, your chainring might even go hit your chainstay and if you’re lucky it will happen at low speed.
