    I'll add a pic on the 80mm rim shortly

    Velo how did they work on 40mm rims. I don't have enough room in the back to go higher than 40 unless I spread it out more. Up front I can do anything I want, but I want it to at least be somewhat balenced. 40r 65f is a reality. I would like 65 r and 80-100 f but I got to do some work.

    I liked them. Used a 40mm at both ends and it worked ok. Probably be better on a slightly wider rim.

    I'm still using it with a 40mm front but I've now got a 80 on the rear. Haven't got round to building the front 80 because I was waiting for a new fork.

    Ok fair enough. I knew they would work on 30mm but that was not optimal at all.

    I figure 40 is minimum I would want to use. I am not doing much on this bike except some tow path and city work so float is not an issue, but who dosent want big fat rims

    I measured 99mm with wire bead, 120tpi, Black Floyd's on Rolling Darryl's (80mm). They are aired up at 14psi.

    Ran them for about 20 paved and 35 gravel miles this weekend. With about two miles of sandy two-track thrown in. No tractions issues. They are game changers.

    When stacked up against other Fatbike racers in a gravel grinder event, the Black Floyd will provide a distinct advantage in rolling resistance and weight. I really didn't notice a loss in traction or handling on dirt roads. In my case it has been good for at least an additional mile per hour over a distance of 35 miles. Was it worth the $180 to get this advantage, no not really for me. But someone podium worthy, heck yeah!

    Even in moderately deep sand, I had no real problems. I saw another biker and a motorcycle rider struggle on the same sandy descent. I only wish I had "Fatbike FaceTime" video on the descent.

    I thought the BF had deeper grooves. However, it turns out the grooves are really just a texture difference in the rubber.

    Quite a few of us have done reasonable length road rides on Black Floyds.

    Couple of mine:
    On & off road A foolish ride - Black Floyd content.
    Road trip Can Black Floyds on your fatbike replace a road bike?

    So I guess I forgot about this post after taking this picture. Or maybe I posted it and can't remember. Anyway, here's a BF on a Clownshoe. I didn't measure it.
