First I need to brainstorm about how to make u brakes or v-brakes for my frames.
Simply put I seek progressive mechanical braking to complete my setup. As is it is too dangerous to keep pushing higher speeds DH without proper brakes.
Keeping the momentum and sliding my way out does really take a toll on the thighs and ankles, specially when road is bad. So mechanical brakes would actually be a huge add up for safety.
Do you have experience in braking with bikes? BMX, mountain bike, whatever. I will gladly take any input.
So far I plan to make a jaw with a cable running on my boot and attached to my leg, so when I pull the cable it bites the wheel or a disk inside the wheel. Braking force depends on how much I pull it.
Sidewall seems the best option then. The contact patch on mtb disc brakes is pretty small, you might be able. To cut one down to the required resistance level if it’s too big.
