i wouldnt go with the v-brake, wears down the rim, its lighter but not worth it in my mind, this bike would look so sick without a brake at all, even with a disk brake it would still look amazing, sickest bike ive seen in a while
do you know what seat he is running? on mine i cant slam my back wheel with a normal pivotal seat on it, and what is the clearance like for barspins with the pedals?
