Your my hero Chi. That was my new idea, and u confirmed it. Although, this turns out to be an interesting topic.(I've done my research) and QR has been used in this situation, but was though to be not safe becouse under extreme braking, the wheel would fly off, in rare cases. But I consider myslef prety knoledgeable in the sport, and remember, in a few cases, both races and movies, nutted wheels came right off as well. I'm still in search of the best method. I have seen homemade dropouts bolted to frames that used normal QR, but are much diff, and stronger than both nutts and QR. If anyone wants u can get the picture.
