Planet X Kaffenback with discs, 29er MTB fork, bamboo fenders, lights and a bag of tools/spares.
33.5lb
The upgrade to disc and swap from carbon CX fork to rigid MTB fork added 2lb this winter but I love the new predictability (braking) and relaxed feel from an extra 30mm axle to crown on the fork. Better for the off road part of my commute.
