What´s the name of internal brake hub from 80s or 90s mtb?
I was given an old mtb with these weird brakes that pull on something near the hubs of the front and rear wheel? I believe the bike itself is 6 or 7 speed with a freehub system and positron friction shifters on the handlebar. It also has a dynamo and this large cateye charger thing with on off switch located at the seat-tube. I took the wheels out of the frame and see this weird hook thing spinning around the hub and I have no idea whether these wheels can be disassembled to be used on another bike by removing the spinning thing so the hubs become normal hubs.
