It's getting colder in earnest, and the oden has become a delicious season. What are your favorite oden ingredients? Apparently, my favorite oden ingredients are cancer. Kick.

Last time, I installed the crank and BB, so this time I will introduce the installation of the rear wheel cog. The cog is a gear attached to the rear wheel. By the way, the large gear on the crank is called a chain ring.

The left mechaka is the freecog to be attached when running with free gear, and the right is a fixed cog and lock ring for running with a fixed gear.

Use this cog turn to attach a cog. When attaching a cog, I use special tools that I have never seen, but it looks like a weapon. The feature is that it looks and looks like a boy's heart.

Attach a fixed cog and lock ring to the one with the step of the screws of the hub, and a free comic on the flat.

Attach the cog first. Wrap the chain attached to the tip of the cog, put weight and tighten the cog.

Once you have a cog, then attach the lock ring. Sprinkle the cog turn on the locking and tighten to tighten. The lock ring is to prevent the cog from loosening while driving, and it is a reverse screw so that it does not loosen easily, so it is attached while paying attention to the tightening direction.

In addition, by attaching a freecog to the other side where the fixed cog is attached, it is easy to change the left and right of the tire, and it is possible to drive with a free gear like a road bike!

The mounting of the cog is now complete.

Recently, I was taught how to take a photo shoot for blog, but it was difficult because the composition was not easy or the focus was not focused. I want to be able to improve the photos of this blog beautifully! !

Then.
