I brought out my 21 year old hybrid bike, and it was a chilly start 40 F (4 C). It will take a couple rides to get used to the gears, which are less granular than the mtb. I also need to raise the seat a touch, and that should do it. I like going down hill and still having pedal. Some day I need to replace both bikes with bikes that have suspension, but then again maybe not. It should be a warmer ride home, somewhere in the 70s F ( 20's C).
