is it fit for american bottom bracket?

Yes, this fits bikes with a one piece crank. This was the standard on American bikes from the early 1900's all the way through the BMX era and into the Cruiser revival.

This is for the old style American bottom bracket for single piece crank sets like the 1979s Schwinn type 10 speeds.

I used it on a NY made Ross Europa3 with a 1 piece crank and it worked great.

As long as it's a ISO square-taper bottom bracket it should work perfectly with this crankset.

First of all -are you able to remove the crank arms using an appropriate tool? If yes, remove the arms and measure the length ... and the actual width of the bracket mount on the frame itself. If you don't have the tools, I suggest not doing this job yourself.

It fits my British Berkefeld. Just measure your opening, and compare it to the specs.

I regret to say I have no idea. The bracket is inexpensive and I suggest you buy it and try it out. If you are mechanically inclined, you might find it easy to adjust so it meets your needs. I think it comes with the necessary Allen wrenches. If it doesn't fit, it should be easy to resell or return.

bottom bracket must measure 123mm from one end of the spindle to the other end

Yes. It takes the modern square tapered spindle. I used a Sunlite tapered spindle bottom bracket unit for mine.

It has a standard external bearing bottom bracket w/shims to fit 68 mm or 73 mm shell widths. The external bearings are also sealed to help keep grime out. I used this to replace an old Octalink bb crankset. I don't believe you can use this for press fit bikes since I don't think they are threaded.

The 2th number in the total shaft length in mm. Take the old bottom bracket out and measure it or run the model number to get the specs. If it's a newer bike you might be able to track down the bottom bracket specs online. If it's a frame with no bracket to measure and you can't get the bike specs online "take it to a shop". Also you need a special tool to remove/replace the bottom bracket. Good luck buddy!

It should. I would suggest reaching out to the manufacture to double check, and be more specific as to which bicycle you have.

Measure the diameter of the bottom bracket shell. If it is exactly 2", then bottom bracket bearing set should fit. I installed this bearing set on a 1990's USA Huffy bike and a 1970's USA AMF bike with no problems.

Measure your bottom bracket to be sure, but this is the most common size I've run into while replacing bottom brackets on bikes I fix. Provided your crank is a square taper and not an octalink or something like that.

No, I think this crankset will be too short/not wide enough; made to fit a 68mm (shell width=width of bracket minus the spindle). You, have to find one that is 73mm. hope this helps.

It's difficult to say. It was supposed to be a direct fit for my Kubota but we had to do considerable altering of the bracket in order to make it work. You may be luckier.

Sorry, I can't find a record of my Bottom Bracket order but would recommend checking out this page for advice.http://sheldonbrown.com/bbsize.html

there should be a label on the bottombraccet itself with all the specs on it. if you cant find the info on the specialized web site the simplest is to remove the bottom bracket and take the info from there.

It is possible. The best way to know is to measure your existing bottom bracket. You need to know two measurements: The length of your bottom bracket shell, which is the tube on the frame where the bottom bracket goes. This will likely be either 68mm or 73mm. Also, you need the length of the spindle where the crank attaches. Change this requires at least two tools specialized for removing bottom brackets and for removing cranks. Without these tools, the job is nearly impossible without damage to your frame and parts.
