I was adjusting the position of my R1s on the handlebar this morning and when tightening the clamp back on... the bolt sheared, leaving 1/2 the bolt cleanly inside the master cylinder housing.

Can this be drilled out / tapped at a LBS? Or is the housing fubar'd? What material is it made of - it is very light but doesn't feel like carbon, or as cold as aluminium or steel in this weather.
I blame the cold weather for the shear, my hands were too numb and clumsy and I was working too quickly. It's not the first time I've broken a brake clamp before now (shame).
