    I've had Slipstreamz Spoilers on one helmet for several years, and would say they work at reducing wind noise. It's not night/day different, but is noticeable and appreciable. They also have a full...

    @Isberrios1 did you use any strategy or pacing, or just do a constant, sustained, best effort? I wonder what the best approach would be for maximizing power over an hour, straight Z4, Z5/Z3...

    Ooh, dynaryder, that was a tempting one, especially since I'd hastily thrown the lock on the other day, but after removing, I still had the issue.

    I also cleaned and adjusted the drivetrain; no...

    That's exactly the claim that I challenge.

    This discussion is formed around the idea that strength only refers to J bend fatigue, which is erroneous. The entire spoke is forged anyway, so really...

    Yes, I understood all that, I just question how you know it. How are you sure the forging is wasted strength?

    I'd definitely go tubeless, and it'd be hard to pass up 1460gm American Classic MTB Race disc wheels with their 24mm bead seat width and wrapped in Hutchinson Sector 28s at 290gm. That'd be a ripper.
