I think we're all experiencing a bit of a warming trend these past couple and for the next couple of days. Although this weather is nice for walking (or as my son is doing, camping and canoeing for his Outdoor Education high school course) but I find it a bit challenging for biking because I have to wear warmer clothing during the dark morning ride (5C, ~40F) and have room in my rack pack for the jacket and tights for the sunny, afternoon ride (20C, ~68F).
The ride this morning was OK. A couple of driveways from my house, I discovered that my front brakes were rubbing but I was already running late so I couldn't stop (in the dark) for any significant repairs/adjustments so I just battled the extra "rolling friction". This afternoon at break, I will take a look at it or just take the short route home.
