Should you adjust the front or rear derailleur first?
In a nutshell, adjust the front derailleur first, then the rear. Show activity on this post. If the derailers just need minor tweaking (they are basically in adjustment but are “not quite right”) then you adjust the one that is obviously wrong, check the overall adjustment again, then again adjust what needs adjusting.
Is SRAM as good as Shimano?
Shimano has responded with its own 12-speed drivetrain using a slightly larger 10-51T cassette. Not to be outdone, SRAM now offers a 10-52T cassette for Eagle drivetrains….Mountain bike gearing.

How tight should the front derailleur cable be?
Holding the cable tightly so it can’t slip, pull up with the pliers to remove all slack in the cable and hold it like this as you tighten the anchor bolt to secure the cable in place. It should now be tight enough so that when shifted onto the large chainring, there’s no rubbing.
Should the chain touch the front derailleur?
The front derailleur cage should be approximately parallel to the chain. If the derailleur cage is rotated too far from this position, it will shift poorly. If the derailleur mount is a clamp type, its rotation can be changed. Generally, the outer cage of the front derailleur should be aligned to the chain.
Why is my bike making a grinding noise when I pedal?
Worn components can create a host of issues, (e.g., a new chain on worn chainrings can make a grinding noise and felt through the pedals.) Once you’ve established that a noise is coming from the bicycle, per- form a quick 4-step check before the bicycle enters the stand.

Do pro cyclists use electronic shifting?
Professional cyclists race on electronic drivetrains throughout the season, but once or twice a year you’ll see some of them swap back to mechanical gearing for the cobbled classics (e.g. Paris-Roubaix).
Should the front derailleur touch the chain?
A properly adjusted front derailleur should shift the chain between the front chainrings but will not throw the chain off the rings. The basic adjustments for the front derailleur are the height, rotation, limit screws and inner wire tension (index setting).
What should I adjust first front or rear derailleur?
What gear should you be in going uphill on a bike?
Low Gear = Easy = Good for Climbing: The “low” gear on your bike is the smallest chain ring in the front and the largest cog on your cassette (rear gears). In this position, the pedaling will be the easiest and you’ll be able to pedal uphill with the smallest amount of resistance.
Why do bikes skip gears?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
