Ok, the last few days have been rainy days which, of course, did not deter me from bike-commuting. However, I haven't bothered to lube the chain because what the hell, I figured, the lube would just be washed right off it the next morning. Except: it didn't rain today. So what do I hear as I start pedalling this morning? The most god-awfully loud squeak I've ever heard from a bike chain!

Unfortunately, I slept in today, so had no time to go back and apply lube... In fact, I slept in so much I didn't even have time for any breakfast! These two factors combined (with some headwind thrown in for a good measure) accounted for my slowest commute since the start of the school year: an abysmal 20 kmph (~12.5 mph) average.

Luckily, there is some WD-40 in my office - not a very good chain lubricant but did do the trick for the return trip (which therefore was much more pleasant for both me and the bike).
