Hey gang, new to the forum and biking in general. I'm putting together a SS with an old MTB in the basement. I'm having trouble with the wheel. I bought a cheap wheel online only to find that I may not be able to convert it. If I put on a free wheel sprocket (BMX style) it will not line up with the front sprocket. Is there anything that can be done to the wheel in the picture to convert? Thanks in advance for the help.
