Re: Im using a 26" front wheel and 20" back wheel any suggestions?
You shouldn't have any problems with the frame, and a 20 in rear wheel? Put a 34-36 tooth sprocket on that baby and you're gonna have better speeds that most of us.
If you put fenders on it though, you'll want beefier mounting brackets and uprights for it, but other than that, you're ready to fly!
