Feb 4, 2021 at 23:03 comment added CCTO They are Shimano IM55's front and rear, which as I understand it, use rollers to activate the drum braking surfaces, so for questions of maintenance and weather resistance I think are like other drums. I don't know if they have the "power modulator" but I never had trouble engaging them as forcefully as I ever wanted to. And I have never needed to modulate speed on long downhills, so the lack of a heatsink never became an issue.
