By changing the number of teeth on the rear tower wheel, the rear wheel transmission changes the number of teeth. In the rear tower wheel, the speed ratio for the vehicle tread is adjusted by adjusting the sprocket, i.e., the number of rotations that the rear tower wheel will undergo after each pedal cycle. To avoid being laborious when driving at low speeds, change the rear wheel transmission to a larger sprocket so that the friction force and acceleration resistance of the rear wheels can be less and more efficient. You can save. In order to overcome friction, exchange a large sprocket with a small one when high speeds are required. In the same way, a trampling speed can achieve higher acceleration, but is also more time-consuming.
With this mounted rear transmission, you can adjust the speed of 6 / 7 at the rear of the bike. It is mainly designed for mountain bikes with iron frames.
This MT60 derailleur is attached to a device that looks like it is If you remove the adapter and reconnect the derailleur directly to the tire hub screw, I think it should work fine. I have attached the Linugr to an old Fuji mountain bike with a derailleur that looks similar to the MT60 and it worked.
There are two "L" and two "H" screws on the rear transmission, along with a gear screw. In the end, the rear wheel is over the large plate, and then the disc is placed on the large plate, and the rear fly is put on The l- value needs to be adjusted Ensure that the screw is positioned As long as the chain is not interfering with the tooth disc and the front drive, change the rear transmission to the small one, and adjust the tooth disc to the small plate at the same time. Adjust the h-value at this time Slowly adjust the torque on the "L" and "H" 2 screws, and then the shift screw. This will ensure that the chain will not interfere with the disc and the front drive. Switch to the first gear of the front transmission as well as the first gear of the rear transmission by turning the manual change. The gear screw may need to be adjusted if there is a shift.

If I had a way to break my chain, it would have been a breeze to install. Since I had to remove a screw from the lower gear and bend the tang at the top gear, I had to remove a screw from the lower There is an Allen wrench on the screw, but it is The metric system does not work for me. In order to achieve this I used my Dremel tool to grind a slot into the head and a screwdriver to use a wide blade.

Video tutorials are available online to guide you in replacing. It was my first time and I found the videos to be very helpful.

The quality of this film isn't high The product was an end item, but it was a great replacement for a broken one on a kid's bicycle. It was also pretty easy to install.

We bought it as a replacement for our old TB The crack in my cheap Walmart granite peak was caused by wear and tear. It works and I think the result is much better than.

My husband had been looking for something like this. The value for money is excellent.


This is a perfect fit.

The pin in one and the bracket in the other is different. It was the wrong one I ordered. I sent back the item and got a replacement in a short time.
