So, I've had at least two flat tires on my way to work. Therefore, I'm tempted to splurge on a pair of Specialized Armadillo's (not the elites...)
However, I am not a particularly skilled rider. I had a pair of racing slicks from the late 1990's (at the latest!) and they were a tad on the nightmarish side - I slid out at 5 miles an hour trying to leave a parking lot.
Seriously - slicks were enough to give me an existential crisis.
At the same time, I'm notorious for being, err, close, yea, that's it. Close to late. As such, I don't really like flat tires. My choices at the bike shop came down to this: cheap gumwall tire with treads and Kevlar Inserts, or a pair of Armidillo's which have minimal treads.
Which should I choose? I commute in all weather conditions.
Speed is nice, but I really care more about not dying and not calling in late from the side of the road than minimizing rolling resistance.
