"Elementary, my dear Watson"

Aug distance: 57 kn

Upper Thomson, 16 km.  After weeks of suffering and wondering what caused my bike to click on pedal downstrokes, I finally found out.

What it wasn't:

• seatpost or seat; 
• fork
• headset.

If it was so, there'd be clicking even as I coasted over bumps.

It wasn't:

• chainrings, bolts seemed tight
• bearings; there was no "play" in the crank
• crankarms; bolts were tight
• chain. This was a major suspect, as I'd botched up installation. But it wasn't, as I'd lubed it, and the links weren't stiff. 

What ut was ... the right pedal. There are reasons why it couldn't have been, so it was the last thing I checked. As Sherlock Holmes said, "when you have eliminated the impossible, whatever remains, however improbable, must be the truth".

Double click

Upper Thomson, 25 km. First, it was one click. Now, with each pedal downstroke, there are two clicks. A properly functioning computer mouse must double click. A smoothly functioning bicycle does not single click, much less double click.

The sound, while small, is ominous. There is no play in my cranks. So what is malfunctioning, such that single click has become double?

By the numbers

Upper Thomson, 16 km. In the past, as I cycle, I’d think about km, km/h, hours, minutes, even calories. This evening, I’m preoccupied by ROI, PE ratio, payout ratio, yield.

If I make the numbers, I can do more km and think about the other numbers!
