It would be helpful if you do some homework and look up the proper names for bike parts. There are lots of websites that have the information. It is also fairly easy these days to post pictures.

If you are too lazy, then you should understand why people here get frustrated trying to help you.
There's no excuse for not trying harder.

You have asked for help quite a few times the last few months, and still are uncooperative about providing useful information, taking advantage of the helpful nature of people here.

You would get better answers, more quickly, if you were not so lazy.
