this is genius. I am a recovering technophile. i used to care. it mattered. then i sold my rocky mountain slayer. and refurbished my old brodie sovereign. it has a cantilever brake on the rear. but it works. and a square taper bottom bracket. and it spins. so do the wheels! and its fun. and it has water bottle mounts. and the gears shift. wow. its a bike. all i ever wanted....
