I was planning on heading out for a nice long ride today -- either Jersey Shore, Nyack, or a Staten Island loop -- but felt wrong for some reason. I don't normally get punctures, but I was really, really worried about being trapped on Staten or something with a flat, and I just had ordered resupplies (tubes/patches/etc) from Nashbar but had not yet received them.
So I decided to ride a few CP laps on the fix for both exercise and to see if i'm too slow to show up for the Monday CP races (answer: yes).
First lap went fine... second lap went fine... cruising around the corner near the bottom of the park at Columbus Circle... PSSSHHHHHHHHHHH.
Roll to a quick halt and see a HUGE (1/2" or so) gash through the tread on my front tubular (a POS Criterium tire made in Thailand. Blech.) Ended up having to walk over to 59th/5th to catch the train home...
Lesson, as always: bring the patches/spares, and friends don't let friends ride crap tires.
