your transmission wears after time, try getting a fluid change, use fluid made for older cars this should help slow down wear and make the jerk much less noticeable
Bike gears make a clicking sound while shifting because the teeth of the gears are engaging and disengaging as they move to different positions, creating a clicking noise.
Low gears provide more torque and are used for starting a vehicle or going uphill, while high gears provide more speed and are used for cruising on flat roads. Shifting to low gear enables a vehicle to move with less effort, while shifting to high gear allows for greater efficiency at higher speeds.
Probably your u joints or the rear end has too much slop.
If it vibrates briefly only while shifting, it's probably the transmission slipping. If all other gears are shifting ok, you're about to loose the transmission.
A bike chain can jump off the gears while riding due to issues such as improper gear shifting, a loose chain, worn-out gears, or a misaligned derailleur.
one of the cam sensors is bad cheap to replace..
To properly execute gear shifting on a bike, you should anticipate the terrain and adjust your gears accordingly. Use the right hand to shift the rear gears and the left hand to shift the front gears. Shift to a lower gear when going uphill and to a higher gear when going downhill or on flat terrain. Make sure to pedal lightly while shifting to avoid damaging the gears.
Friction shifting in bicycle gears involves manually moving the gear lever to adjust the position of the chain on the sprockets, while index shifting uses a mechanism that clicks into preset positions for more precise and consistent gear changes. Friction shifting requires more skill and finesse to find the right gear, while index shifting offers quicker and more reliable gear changes.
The shifting mechanism on a bicycle works by moving the chain between different sized gears on the front and rear wheels. This changes the resistance and speed of pedaling, allowing the rider to adjust for different terrain or riding conditions while in motion.
Using brifters for shifting gears on a bicycle offers several advantages. They allow for quick and easy gear changes without having to move your hands from the handlebars, providing better control and stability while riding. Brifters also offer a more ergonomic and comfortable shifting experience compared to traditional shifters, making it easier to shift gears while maintaining a strong grip on the handlebars.
if it is automatic the transmission could be slipping if manual the throttle could be sticking
The advantages of using an SRAM grip shifter for shifting gears on a bicycle include quick and precise gear changes, easy accessibility while riding, and a comfortable grip design that allows for seamless shifting without having to remove hands from the handlebars.
