Grabbed the usual fixie for the the commute but noticed some weirdness in the front tire (hard to explain), so I rode my old Bianchi instead. It's a great bike that doesn't get enough love. Very pleasant commute - warm but not too hot, and negligible winds. I noticed a strange squeaking noise whenever I ramped up the wattage (uphill or starting from stop). When I was locking up, I noticed the rear wheel was off center (one side had slipped forward in the dropouts) - my guess is that the tire was rubbing the frame with the added torque. I centered the wheel and will test my theory going home.
