Using a BMX 1 pc crank on a 5 speed

[GreatWhite00]

Can you use a BMX 1 pc. crank on an older five speed? I want something I can use with a chainwheel of my choice. Right now the bike has an old 1 piece crank similar to other 70s bikes.

It looks like it will work, but I don't have any parts to test with before I order.

ya, BMX one piece is interchangeable with the old style Schwinn Murray etc. one piece cranks. the pitch on the BB threads is different on Scwhinns then all the rest. :roll:

Cool, thanks for the response.

I want to combine many bike styles all into this next one here.

The bike is a grayish blue frame with some Firestone stickers on it. I think I want to go white and maybe sky blue and leave the frame how it is. Should be intersting.

Also, what freewheel tool should I get?

The bike is this style:

I see Shimano, Sun Tour 2 pin, BMX, etc on Amazon.

I want to switch out the guard piece behind the gears for the new wheels.

If the bike has the "american" style bottom bracket you can use a bmx 1 piece crank, this type of bottom bracket is found on low end department store road bikes (k mart, allpro, jc penny, wards, huffy, sears, etc). If you bike has a square taper or cottered crankset with a threaded bottom bracket (like the one in the photo) you cannot use a 1 piece.

My bad. The bike has a 1 pc on it now. I just realized that the picture I put up is a 3 pc.

I was going to use a bmx 1 pc with a bmx chainwheel.

It should work fine, I've done it quite a few times converting 10 down to 5. Loads of different chain rings out there for BMX. This old Varsity now sports a "new school" one piece crankset.
