Not the best commute this morning. My legs were tired from riding a fast metric century on Sunday. That was bearable by riding slower. What made the ride difficult was my rear brake shrieking like a banshee every time I had to slow down. Ironically I had cleaned and lubed the rear wheel over the weekend. When I got to work I examined the wheels, and the rim and spokes were splattered with black grease. Apparently the new lube I am trying out is very messy. Not good. On the plus side, the weather was great this morning.
