<p>Went out on my Cervelo c3 the other day. After riding down Kirkstone Pass every time I pedal hard there’s a rubbing noise from the rear disc when my left leg’s near the bottom of its stroke. It’s never done this in 18 months. Been back to the shop to be fettled but it’s still doing it. They tightened the through axle and trued the wheel slightly. Anyone out there with a theory?</p>
