In this how to we will be looking at how to replace your disc brake rotor. After a long period of use, your rotor will be worn. A way to check is to use a caliper and take a measurement of the rotor where the brake pads make contact with the rotor then take another measurement at the section next to the brake pad contact surface, if the width of your first measurements is less than the second then it's time to replace your rotor.
What is a 1 x drivetrain and why should you do it?
A 1x drivetrain can be 1x9, 1x10 or 1x11. The number in front of the `x` is the number of your front cogs attached to your cranks, in this case 1 meaning that you only have 1 chainring attached to your cranks. The number after the `x` is the number of cogs on your rear wheel, the latest tech is at 11 cogs, for example 1x10 is a system that consits of one chainring and 10 cogs on your cassette.
Cleaning your bicycle can be harder than cleaning your car as bicycles have a lot more hard to reach places and are full of exposed cogs, chain and spokes. For cars you just use a sponge, hose and a bucket and you are set. I have been using the bucket and sponge for a long time, while this can get the job done, it can be time consuming if you are pedantic about the job done, wanting every available space cleaned!
This How-To can be used on road bikes with Shimano rear derailleurs whether you are installing a new derailleur or adjusting your dysfunctional derailleur. This guide can be used on most Shimano derailleurs with some small variance on some models but the principle of installing and adjustments are the same.
If you are looking at tuning your shifting performance or to re-index your gears or performing a maintenance on your rear derailleur, disconnect your gear cable, turn in your barrel adjustment and jump on to Step 2.
