No wonder I lost your message I was looking in the wrong subject.
“If the valve is located centered on the rim, they won’t work with disc brakes”.
I am puzzled by this statement. Are you indicating the valve stem is located between the spokes and not on the outer rim like other car wheels?
Please let me know about the steering wheel.
Also I posted a question to you about the rear suspension. When you have time please review and see if you can answer it. I’m sure others will be interested in your observation.
