Why does my mountain bike make noise when I pedal?
These super common sounds are usually due to DIRTY or DRY bearings. You’ll often find that after riding your bike for a while or in harsh conditions these noises start to creep in. Areas to check if you’re hearing these noises would be: Crankset/ Bottom Bracket.
As for a bottom bracket, on the low end, maybe 5000 miles. The basic Shimano one most people use (UN51/55/similar) can reasonably expect 10k+ miles. But sometimes you get unlucky and get a bottom bracket that lasts maybe 500 miles.
Most surprisingly, what often sounds like a bottom bracket creak is usually something else. Most of the time, the true cause is a loose chainring bolt. Tighten ’em up and that’ll quiet most creaks. After you check the chainring bolts, look at the pedals, crank bolts, seatpost and seat.
Why is pedaling so hard?
A bike is hard to pedal because it’s in the incorrect gear for the terrain or because of excessive friction. Changing to a smaller gear or reducing the friction makes riding easier. The cause of friction can be brake pads rubbing against the rim or disc, insufficient chain lubrication or low tire pressure.
Why is my bike creaking 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.
Very worn bottom brackets will actually make a grinding noise. I’d fix it now if you’re getting these symptoms. Grinding is a sign of bicycle arthritis and is easily solved with new bearings. Bearings wear out and can lead to damage if not replaced.
Almost anything can be taken apart without proper tools, including bottom brackets. it, but it can be done. The right tool for the job(any job) makes life much easier and will lower your frustration level by leaps and bounds.
How do I know if my bottom bracket bearings are bad? Spin the crank while holding the bike with one hand. If you feel an obvious rumbling or grinding feeling, the bearing are wore out and the unit should be replaced. Very worn bottom brackets will actually make a grinding noise.
