And now mine... Whatever Curt Harnett and Marty Nothstein prefer is probably based on the established standards for track racing. I may be totally wrong on this one (really) but I have the impression that QR skewers, properly adjusted, exert more force on the dropout face than track axle nuts, properly torqued. This may just be some theoretical gibberish based on thread pitches and cam profiles that totally breaks down becasue it doesn't account for various frictional forces, the area of contact between fastener and frame and so on, but I have read (in more than oine place) that QRs grip better. As I recall, this discussion was always in the context of arguements surrounding yet another QR product liability suit. In any event, I can see where elastic deformation of the skewer itself may be significant enough to cause a wheel to let go under extreme loads. But, while Marty may exert three (okay, five) times the force on the pedal that the rest of us do, I'll speculate that many of us are just as likely as he is to pull a wheel due to the extreme loads allowed by the 24x32 gearing on our touring bikes.

First, they are track ends, not dropouts. Nutted axles are perceived to be stronger than quick release although there appear to many riders who say QR's are sufficient. Try selling that to Curt Harnett and Marty Nothstein.
CR content...on many of the older fixed road bikes , axle retainers were used in conjunction with track ends, providing the ultimate in wheel security. They also make chain tension and wheel alignment a cinch. Yes they are a pain when changing a flat but who thinks about that when they go out for a ride.
