I emailed Harry vs. Larry to ask them what the maximum rotor size that would fit on their first generation bike frame and they told me 180's would fit.

But when I installed them, the rotor is rubbing on the frame. Did I do the install incorrectly? This is my first time installing rotors. Or was I misinformed and need to go back down to 160's?

Also, the IS to Post adapter for the calipers came with these little plastic… spacers? I don't know what they are. How would I use them? Or do I need to use them? (And if I am going back down to 160's I guess it doesn't even matter)

Thanks!

    Looks like your frame won’t fit 180mm rotors unfortunately.

    The plastic things are meant to clip over the bolts that hold your caliper on and keep them from rotating. I’ve never used them and I’ve never had the bolts come out even on my trail bike.

  2. Yep, too big. Although i use a rotor that is too big for my fork as well. Works fine even though has only a <1mm gap

  3. Do those ice tech rotors shift the disc outboard at all? It kind of looks like, because of how the disc is riveted to the hub, the disc itself isn’t in line with the mounting point. Different rotors might fit. But it’d still be *tight*.

    It’s hard to install a rotor incorrectly, really the only thing to look at is the direction arrow.

    There’s a greater chance you installed the wheel incorrectly, but again that’s pretty hard to mess up.

    Chances are you were miss-informed or the frame just doesn’t have the clearance the bike company thought. It’s normal for it to be close, but the rotor shouldn’t touch the frame.

    Is there a way to make that “puck” holding the disc a little thinner?

    Maybe make a step so the disc sits inlaid like the large gear on crank

    I know not everyone owns a small lathe, but we all like to tinker here
