SOURCE: I am having problems with my Shimano front derailleur

Adverse temperatures can affect metal, and left idle over time the cables can stretch.. It needs adjustment. Usually the is a pair of screws on top which limit the movement of the derailleur.

SOURCE: what components go on a Colnago Mexico frame?

You should be able to find old Campagnolo parts online to mount on that frame. He also probably ran those old Campy parts and Cinelli stem/handlebars.

SOURCE: What is the proper replacement

Go to a bike shop that specializes in Colnago or one that is willing to order that part for you. You may find one on ebay but it is doubtful. Where did you get the bike? that shop should have them. Good luck

SOURCE: Describe your shimano xtr rear derailleur spare

Broken inner plate can be a potential warranty. Contact your local bike shop and they can process the warranty for you, if it isn't a warranty then the same shop can order you a new plate.

The only other solution I can think of is to shorten the chain and make it a three speed by eliminating the rear derailleur all together. If you have found a way of remounting your derailleur though I would go that way. All the best in the Ironman

If it's "broken" or even bent it will have to be replaced. Your frame or derailleiur hanger may also have taken a fatal hit.

You should consult a Bike Shop.

If you still want to DIY you'll need to obtain some specialized tools and skills.

Mongoose 21speed spear derailer is bent. bought at yard sale 60.00 dont want to put much money into. what is the best way to fix this. how much? Want to use as spare bike. it is rideable but how long....

A new Rear Derailleur may cost more than you paid for the bike. But is IT bent or is it the derailleur hanger?

Search the web for "fix bent derailleur"

Steel frames can be re-formed but not most other materials.

Someone in your club should know how to deal with it and maybe even have an old derailleur hanging around.

Plate That Derailleur is attached to is bent. How do I unbend it. Where do I find wrenches/srcrewdrivers if I need to remove derailleur from plate.

If you mean the frame member/dropout to which the derailleur is attached, CAUTION!!!!

A real Bicycle Shop will have the tools necessary to straighten and align it.

Read this:

Or you could just wing it and use this procedure...

As far as where to get tools??? Special tools can be found at a Bicycle Shop.

I need a derailleur hanger for a Schwinn S-25 dual suspension mountain bike. I don't have the hanger. Is there a part or model number for the hanger so that I can order a new one?

Most bike shops can match up the broken pieces. If that doesn't help check this link to see if you see one that looks like yours.

In case you are not aware Schwinn folded in 1999, The name is now being used by Pacific Cycles. If all else fails you might be able to order one from them. Good luck.

You need to replace the main pivot bolt, something (most likely a tab) is broken. This one is best taken to your local bike shop for inspection. There may be something your missing like a crack in the body or another broken part. Link to Manual.

You can also contact the SRAM customer service for support, but they will refer you to a shop to take care of the problem and order any parts on this type of problem.

The chain is rubbing on the rear tyre when its free wheeling. what do I do?

You may have too large a tire on the back for the bike. However, if the derailleur hanger is bent, this could also cause the problem. Flip your bike over onto the bars and seat and make sure the derailleur alignment is good (vertically and longitudinally straight). If the derailleur hanger is straight, then you will have to use a narrower tire in the back.
