With loaded bike, it'd really make a big difference, as, for me, who is used to "normal brakes", it's already noticeable and annoying in relaxed, commuting riding. I use a v-brake lever, not recommended but it allows to pull more cable to minimize drag in a resting position. If it is being ridden dry for weeks, the drum and/or shoes are damaged beyond repair. Roller brakes are not the best candidate for set-and-forget. But I also read that a Vbrake Lever(long pull) may work better. Going over the handlebars has more to do with braking power, and any good braking system will be powerful enough to cause that. Those are the limits of that technology, and among the main reasons why rim and disc brakes were introduced. For example, the 45s I've got were on a used bike I bought, and despite a strip-down and regrease, have never braked particularly well - they just don't have the stopping power any more.

Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Disc brakes are more efficient, provide better stopping power, dissipate heat easier, and work better in wet conditions, all while being less complex. You see where this is going? However, I consider braking to be one of the most important functions on the bike and I simply cannot accept such reliability. The RollerBrake is cable-operated, but as with coaster (backpedaling) brakes, the braking surfaces are all metallic, and they are grease-lubricated. And yes, I do ride agressively. At the same time, disc brakes cannot be used as parking brakes because they expand when hot and contract when cold.

Thanks for contributing an answer to Bicycles Stack Exchange!

Even if you had cooling fins the size of the wheel, you are generating heat inside the hub, and that heat has to travel out to the fins, which is surprisingly slow. So Shimano roller brakes have noticeably lower stopping power compared to the classic bicycle drum brakes, but also a lower tendency to lock up the wheel. One reason disc brakes are better at dissipating heat is the disc is open to the air, and the pads only cover a small portion of the disc. Convert used road bike or MTB for touring?
