I zipped through a quick 11-mile ride to see if the stupid rear tire would go flat on me again. I made it home in a smoking-hot 16.2 mph pace without incident. Time will tell if I have a slow leak.
Assuming all is well, I am left wondering what caused my two flats in short succession. I see two possible explanations:
1) God’s will.
2) I overestimate the ability of the Crosstrail to handle bumps in the road at speed. I routinely hit “transition areas” where bike paths intersect with streets at speeds over 20 mph. These areas typically include a gutter and/or a metal transtion ramp. This may be more force than the tires can handle.
There is little I can do about Cause #1, so I will focus instead on eliminating Cause #2 by being a little more careful around these areas instead of slamming into them with reckless abandon. We’ll see if that does the trick.
