    No I didn't. He said road disc is just "mtb stuff" and "heavy crap". It's not. The calipers are different than MTB. 138g for a caliper is frigg'n light.

    And of course, rotors aren't "heavy stuff". Pretty impossible to make them lighter.

    but the weight is close to the hub, so it is definitely not adding much inertia to the wheel whatsoever, unlike having heavy rims and tires which do add a ton of inertia to overcome when accelerating
