So far my experience with coaster brakes is perfect in terms of braking force. Not so much with my roller brake but I’m positive there is room for improvement.
I’m gonna go head and say that the roller brake is better. Base on a few pros like heat and wear and tear is isolated to a mechanism that is removable and replaceable. Without opening the hub.
Unlike the coaster brake that is destroying itself from the inside out.
also others that I didn’t even think of like what if your feet leave the pedals?
No brakes!
I think I’m going to go with the roller brake. I just thought it looked funky and I didn’t want to have to run the cable back to it. But oh well.
